Brakes help. PLEASE ASAP

[jsuh s14]

Okay so heres the deal. my brakes were horrible. i had a leaking rear right caliper, so i replaced it with one from a junkyard. Still no fix. i would press the pedal and it would hit the floor, and no stopping... a very gradual stop. so.. i figure... hey bleed it. so i bled the system properly more than 15 times. still no fix, and the brake pressure feels horrible. so i figure master cylinder is bad. i change that to a z32 17/16'' tokico BMC. the pressure is back, but i still brake bad.. so i figure my pads were bad. however, at the same time, i came across a decent deal. 30mm z32 front brakes, SS conversion lines, and Brand new slotted/cross drilled rotors for 350. So i figure.. why not? i put those on, and the pressure feels solid, like braking should be. i pull the car out for a drive, and the brakes are STILL bad. there is SOLID pressure, but the car simply wont stop. Please help me on how to fix this problem. I cant think of anything else to do. thanks in advance for your help

[Blackparade]

is your brake booster noisy?
if so, your booster may be bad.
you might be able to check by going to an empty parking lot. disconnecting vacuum to the booster but plug the line, so that it doesnt leak. accelerate a lil, then try to brake. if it feels the same as before, than theres something wrong with the booster. let us know what happens.

[aznpoopy]

try adjusting the brake booster

maybe pads not properly bedded
but i'm assuming you have shit cheap pads that don't normally require and intense bedding procedures

[Z U L8R]

it's your brake booster, make sure you have that one way vacuum check valve inline in the hose from the brake booster to the intake manifold. pull out the valve and make sure your booster can get a blow job but if you were boosting the boost wouldn't get passed that check valve oOOOOoo BUKAKE!!!

While I wouldn't exactly describe it that way, it does sound like the vacuum to your brake booster has become insufficient.
Look for vacuum leaks, etc.

[gotta240]

i vote brake booster. JMO

thanks for the input guys. however, i did a minor test. i unplugged a vacuum line from the booster and plugged it up. the pressure feels different,. you can tel there is no brake booster. so im guessing the BB is still good. All the pressure feels solid when i brake, but the brakes just simply wont brake. please give more input please.

Why would you assume that he has cheap shit pads?

[OptionZero]

Why would you assume that he has cheap shit pads?

you don't think that's a fair assumption 75% of the time?

original poster:
you're sure no fluid or air is leaking from any line, fitting, or caliper?
i've had loss of pressure from upsidedown calipers, to leaking MC, to torn piston boot inside caliper

if the problem existed even before you swapped to the 3z brakes, then it must be something before you changed, which would be your rear brakes or your booster (As mentioned) or some line or fitting somewhere

[Z U L8R]

i was gonna suggest the rubber brake lines that run to the calipers being swole up inside but you said you had steal lines...at least in the front anyways. optionzero's correct though, the problem was there before you swapped the fronts, and it's still there now, so it's either the rear brakes (as in calipers/pads), the booster, the proportioning valve, or a steal line is crushed.

did you check the one way check valve like i said or no?

[OptionZero]

if the lines are used...well, even SS lines can be damaged if they aren't covered like the SPL or some quality ones. Rocks and shit can cause a leak.

[jsuh s14]

LOL thats the funny thing. the lines are brand spanking new. they were in the box when i picked them up. so yea. the brake feels SOLID, but when i brake, the calipers simply wont stop completely

[jsuh s14]

bump.. anyeone?

[ixfxi]

its not the brake booster - if that was the case, you can just test the car in the OFF position. when off, i can still manage to stop my car(s) without the use of the brake booster, just works like manual brakes.. needs some effort, but car still stops, no problem.

you mentioned that the pressure is OK, but the entire time you've had problems with one thing - getting the car to stop. i understand now you have pressure, but are you sure that you did a good job bleeding the master cylinder AND brake lines? you really want to make sure that is out of the way. also, does the car have ABS?

last, you never mentioned the pads. if your pads have oil on them, you can pretty much kiss them goodbye. you have to make sure that when you're assembling your brakes, that the rotors and pads do not get oil on them. make sure everything is brake_kleened.

did your brakes EVER work? something seems fishy here, it really shouldnt be this bad.

[OptionZero]

i wonder could it be something as lame as just worn out pads, rotors, and shit tires?

you really dont have to hold an a**hole position on the subject...

[OptionZero]

and given that you've offered no advice or even a random suggestion, maybe you should keep your asshole position of ME out of this thread

more to the point, my asshole position hasn't been disproven yet, so maybe you should SHUT THE FUCK UP

1st of all, this is my car, only my lil bro posting shiet up...trying to diagnose the problem...

2ndly, the car isnt all that ghetto... the pads are hawk hps plus... and if you want a detailed list of whats on it ill let ya kno...

and im sure you get the point... there are more parts that im sure i left out....

and if that still seems too pathetic for you, you can always scrutinize the build of my 1998 nissan skyline gtr which did make 611 awhp on 91 octane on low boost.... hks crank to hks cams...

and if you really want a pissing contest, ill be sure to show you my 2005 sl55, or my tahoe or my prius...

the point being, yes some people have ghetto ass cars (alot of times out of their control), but it was somesone looking for genuine help... and maybe you have alot of knowledge or a nice car, but dont be an asshole about it....

I hope this disproves your arrogant response....

[OptionZero]

Your response was worthless, because it offered less help than I had.

Your response did, however, prove your own worthlessness: You own a Toyota Prius. End yourself.

I don't care if your "mod list" included a gold plated cock welded to your girlfriend's forehead. It doesn't make you less an idiot.

[Irukandji]

Ooo Shiiyeettt that boizz got h3llla mods yo. HIN that shit yoo'LL get furs Prizzeee fo Best Drift caR.

But seriously.. it isn't 1992, and we aren't 13 years old... Listing your mods only make you look fucking stupid.

[OptionZero]

Yeah, i've never seen an s14 with an SR (S13, to boot) before. OMG YOU OWN A SKYLINE.

and an SLGay. And a Tahoe. And a Prius. That's a pretty sad garage, actually, given the amount of money spent.

[jspecusa]

Why would you assume that he has cheap shit pads?

expensive brake pads don't stop well at all during normal condition.
they only brake well after heating up under heavy braking.
either way the only way to solve his brake problem is to have someone else drive the car and get a second opinion.

[cdlong]

not to mention there's no such thing as hawk HPS plus pads. they are either HPS or HP+. HPS's are street pads and should work fine cold, HP+'s are semi race pads and don't work as well cold but should still work ok.

but if you changed the brake pads, rotors, and MC, it's either the lines are blocked, the booster is weak, or you need to slow down. try throwing a z32 booster on there and power bleed everything.

LOL...oedipus complex???

for real man, you dont need to be an arrogant asshole, carrying such a "im higher than almighty" demeanor. The point being we had questions for a real problem...

listing mods was purely dispite the lame assumption that people who would have questions about theyre car would be broke ass chumps who dont kno shit... apparently i have run into a popularity contest w/ some on the board when it was really directed to one individual...

in anycase if anyone does have any further suggestions, or have run into a similar situation, please do not hesitate to post...

thanks

[aznpoopy]

did you bed properly, as option suggested earlier?

hps stop crappy until they are bedded in my experience.

[jkgaddis]

ok, so even though option may have had what you feel is an assholeish approach to things, he was still trying to help. so that would make you an asshole. i personally cant believe you are that butt-hurt about someone calling your brake pads shitty. also, if your such a god-like car man with all your "builds":jerkit: then why cant you diagnose a simple brake problem on your own? seriously, the brake system is fairly simple. however, it will be impossible to diagnose over the internet. if you are too incompetent to fix it yourself, take it to a shop. furthermore, it great that you have a 611 hp skyline.... i have a 205 hp 240... that has working brakes!:bowrofl:

[jkgaddis]

also, if i were you, i would disassemble the entire brake system and blow out all the lines and rebuild the calipers. then, reassemble and bleed them. also, make sure your booster is adjusted properly. also make sure you clean the rotors really well with brake cleaner and make sure there is no grease or anything on the pads. viola'. and if its still broke drive your prius to a shop and make an appointment for the 240.

Wow, for someone who preaches against being arrogant, you're awfully hypocritical (and ignorant as well).
Your ignorance is displayed by attempting to apply "a stage of psychosexual development where a child of either gender regards the parent of the same gender as an adversary, and competitor, for the exclusive love of the parent of the opposite gender" to something about cars.

You say you don't carry a 'high & mighty' demeanor, and yet you've all but bragged about the parts list on an S14, the fact that you owned a billion horsepower R33 GT-R (OMG SO SICK JDM TYTE!!!) and currently own 17 other cars that are so much more than we can afford, pal.

Broke-ass chumps. Yeah - that's totally humble, dude.

Seriously, you've been spoon fed all the possible ailments to your braking system. What else do you want, someone to do the work for you and tell you how cool you are while they're doing it? :rant2:

[OptionZero]

Is chosun_GTR the same guy as the original poster, jsuh s14?

I was under the impression chosun gtr was just some fool that had nothing better to do than to feel butt hurt about how i posted while trying to help ANOTHER PERSON. Only the sorriest of shitheads would take offense from words not even directed toward them.

Anyways, go drive your Prius pump up that ego of yours, you're "saving the environment"!

it was a sarcastic response...not to be take literally, but has been commonly associated with complexes aside from the literal Freudian defintion...

what is it that you are implying, that you dont like or aprreciate the gtr? Was is the point of "(OMG SO SICK JDM TYTE!!!)" this statement??? Was that an attempt in mocking me for owning a GTR?? An assumption that I would do or buy things simply for the fact that it is JDM?? Interesting...statement considering your signature....

Broke-ass chumps. Yeah - that's totally humble, dude.:

re-read the context in which it was written...

no...just suggestions... Like I said... it wasnt about anything else, just an unneccesary comment...and someone else had also posted questioning why he option had assumed what he had assumed... I then posted that he did not have to hold an asshole position on it...

the response i get is "my asshole position hasn't been disproven yet, so maybe you should SHUT THE FUCK UP"

if it was a challenge to "prove" then ive obliged...in the process if i have come off arrgoant, my apologies...people who do kno me, kno that i am a descent guy, well most of the time...

Lastly... Option you called me out saying me to prove something to you... the issue is that i dont have too many ghetto things on my car...and ive also hoped to prove that i dont have too many ghetto things overall....

thus far ive heard how my cars suck and how you mock the prius... if you got better id like to see...

I never asked you to prove shit, you're the one that thought you were so important you had to share a meaningless list of modifications and cars with us.

Maybe you should do some re-reading:
I said that my speculation about the original poster's brake problems had yet to be disproven, and as it stands, he STILL has not replied telling us whether he had or had not correctly bedded his pads and rotors. None of that has anything to do with what you do with your money.

Furthermore, even if I had asked you to prove something to us,...you still haven't proven shit except that you're a tool. Posting a mod list? Sorry, this isn't the "Readers' Rides" section of fuckin Import Tuner, try NICO if u want people to jerk off your ability to order or pretend to own parts and cars.

In summary:
This thread was about a brake problem.

I offered the OP a suggestion.

You somehow got offended with how posted to the OP, calling me an asshole.

You did not offer any advice of your own regarding the brake problem

You acted like an idiot by using this thread rather than a PM or rep to attack my attitude without addressing the validity of my suggestion.

You posted a list of parts and cars to show how cool you were.

No one agreed.

You come back to defend yourself.

You continue to suck.

I think we're up to speed now.



Oh, by the way, I drive a puke brown Geo Metro and have never owned a 240sx before. Guess what? I'm still not impressed with anything you claim to own.

Does that hurt your feelings too?

[cdlong]

we don't care about all the non-ghetto stuff on your car, just the brake pads. i would say get back on topic but i think we've offered all the help we can over the internet.

and we're certainly not going to get into hybrid pissing contest.

[zero.counter]

Please get back on topic. What is the current status?

interesting....i need to re-read??? THIS IS MY CAR...my lil brother was posting up questions... (this was posted in the 2nd part amongst my posts)this is not a "us" vs me thing...you come off like an ass and i didnt like it....let me re-cap it for ya

you post: "but i'm assuming you have shit cheap pads that don't normally require and intense bedding procedures"

another member posts: "Why would you assume that he has cheap shit pads?"

you post: "you don't think that's a fair assumption 75% of the time?"

and then i post: "you really dont have to hold an a**hole position on the subject..."

and then you post: "and given that you've offered no advice or even a random suggestion, maybe you should keep your asshole position of ME out of this thread

more to the point, my asshole position hasn't been disproven yet, so maybe you should SHUT THE FUCK UP

and thus the flame continued...

youre right maybe i should have taken this off the thread and continued it on pm, but any case what is done is done.... i said you didnt have to hold an asshole position on it... and did not call you an asshole...

your brash, and obnoxious disposition is what sat wrong with me...and you continually talk shit... Im letting you know that I am not part of the 75% that you think would have "shit cheap pads"...(which i think is just something a complete dickhead would say)

i ask you again... you mock me... show me better....i dont deny you own a 240, and hell you can own a puke brown Geo Metro if that floats your boat, but am i gonna sit back and talk all this shit...and if you really think i come here to "claim" i have these things, get a life, im sure even in my post history, i have sold parts off of my s13 a few years back...and if that isnt sufficient im also part of the gtr community on freshalloy....come on board, and inquire about me.. i am a very helpful friendly guy, but i wont sit idly by without having to say what i have to say....

The brake booster will be changed this week and yes the pads were bedded correctly...

[ixfxi]

1) Its not the brake booster
2) Its not the pads (I have HPS pads on one of my cars, they brake well EVEN when cold OR new)
3) Most likely, you still have air in the system.

If your pedal is too stiff and requires too much effort, THEN you should look into your brake booster OR the check valve that is intermediate with the main vacuum hose.

Just mash the brakes, see how it feels. As for all the other discussion, stop taking all this shit seriously and quit pussy-footing with everyone on this forum - save that shit for off-topic, where trash talking is welcomed.

I dont care if this is about a Skyline, Prius, or Geo metro.. its a brake problem, so keep that shit on topic.

ps: Bring your skyline by my shop, buy some decent lights for it and spend some money - clearcorners.com need support from baller customers like you! (haha shameless plug) Shit, atleast I'll be honest enough to tell you why your shitty brakes arent braking.

HooOooooOoooray for you! You're not in the 75% percent! That doesn't make the assumption any less valid, doesn't make you any less of an idiot for clarifying the situation earlier.

Since you've already posted a mods list and car list, why not post a list if all the songs you've ever sung, and all the guys you've fingerbanged!

hey, guess what, you could own a mclaren F1, but the brakes on your 240 still don't work! how fitting for someone who parks his prius next to his tahoe

I'm closing up this festering sore.
To WHOMEVER is having the brake issue - troubleshoot it and eliminate causes. Use common sense. You shouldn't need to start a new thread, as all pertinent causes/solutions have been posted about in this thread.
