New pads, weak ebrake? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

THEMkris · 12-06-2007, 01:10 AM

okay so i just got done installing new hawk hps on my s14. had to replace the rear rotors in the process. i worn in the breaks for a good hour or so as well. but still the ebrake is not catching nor locking up the rear wheels. what could be wrong?

**EDIT**

i need to pin down the problem..

1. brakes have a lil "drag" (hear brakes dragging on rotor)
2. stepping on brake or pulling ebrake makes sound louder.
3. ebrake is weak. does not lock wheels at all.
4. piston on rear caliper is ripped. no leaks.
5. improper wear on brakes (not fully using entire brake pad surface)

what can be my problems?

the only thing i can think of is that my piston is bad. the caliper isnt retracting all the way, isnt pressing the brake pad sufficiently, and pushing in the brake pad crookedly.

any other reasons that i should keep in mind?

Dousan_PG · 12-06-2007, 01:12 AM

u trying to do it for drifting?

with those type of pads i usually do a lap or two w/ the ebrake up a bit
heat the pads up first
get them in the right spot
then they'll grab like crazy

had to do it a lot when did the touge drift
drive into the mounts w/ the ebrake up enough to cause some good friction
then it worked great

THEMkris · 12-06-2007, 01:15 AM

well i tried breaking them w/ some ebraking. i know damn well the pads are heated up so i try to at least do a lil 180 and the rear brakes will not grab at all.

Dousan_PG · 12-06-2007, 01:16 AM

tighten up the cable then
thts usually it

with a stock rear caliper
after using fancy rears for ebrake
i went back to stock pads cheapies from autozone
they dont need any heat to lock and lock up fast and easy

THEMkris · 12-06-2007, 01:20 AM

also, when im just driving, with the windows up and the radio off, i can hear the rear brakes "rubbing?". is that normal for new pads?

Dousan_PG · 12-06-2007, 01:20 AM

not at all
u probably installd them wrong

THEMkris · 12-06-2007, 01:21 AM

i mean, its a really faint sound. not like its loud or anything

Dousan_PG · 12-06-2007, 01:23 AM

i never hear my rear pads. ever

THEMkris · 12-06-2007, 01:23 AM

how the hell could i install them wrong? fuck this is frustrating.

THEMkris · 12-06-2007, 01:38 AM

do you think i tightened the two pin bolts (the two that are connected to the piston) too tightly?

THEMkris · 12-06-2007, 02:47 AM

please help. i torqued them down to 20 and the brakes are still "rubbing". i just got back from under my car again and with the rear lifted, if i spin the wheel i hear the same noise.. what the hell is going on. please help.

Canaduh · 12-06-2007, 10:24 AM

are your shims installed?

THEMkris · 12-06-2007, 10:24 AM

ummm they never came with shims. i assumed the part on the back of the new pad were shims.. am i wrong?

aznpoopy · 12-06-2007, 10:36 AM

shims = little metal clips. that won't come with your brake pads. they keep the pads from rattling.

as for the noise you hear, its a floating caliper assembly. the pads may touch the rotor a little while not driving. it's not a problem unless they are actually dragging - i.e. braking while you are not braking. if that is the case i would guess you did not reset the piston sufficiently during the install. either that or the caliper is seized.

THEMkris · 12-06-2007, 10:41 AM

okay, the dust boot on my piston is ripped. that seized my brakes last night after drifting and hitting some dirt.

i think they're seized. what exactly happens when they're seized?

Canaduh · 12-06-2007, 10:44 AM

you get new ones. Haha.

Or rebuild them

or just upgrade them altogether. <---i recommend that one.

pbcstylez · 12-06-2007, 11:10 AM

oem rebuilt ones are like 70 bucks, either get a replacement or go z32

THEMkris · 12-06-2007, 05:38 PM

where can i get them rebuilt? is that 70 each?

aznpoopy · 12-06-2007, 06:07 PM

you don't have to. just go to your local pepboys/autozone/kragens/napa
they can order you already rebuilt calipers
then you swap em out and give them your old cores to get a little money back

gotta240 · 12-06-2007, 07:46 PM

What side is it? i have a stock rear caliper i'd sell you for 25 bucks plus 5 for shipping.

THEMkris · 12-06-2007, 09:17 PM

well both really. the passenger side is the worst. where in so cal are you?

does any one know how to rebuild the rear calipers? i just bought two kits from auto zone.

THEMkris · 12-06-2007, 09:36 PM

dammit, i just looked at the kit and it doesnt come with springs, washers, etc. just rubber seals. i might as well just buy rebuilt ones from autozone.. thanks aznpoopy....

thats what i did, and i dont regret it at all. new calipers FTW! and lifetime warranty!

THEMkris · 12-06-2007, 09:48 PM

how much did you get them for? front or rear?

i got my S13 rears from autozone for i think about $300 and got $100 back for the cores, so it came out to just about $200 total. that was for completely loaded ones, they had pads/clips/everything. just bolt up and go. but oh yea. if you go that route. make sure you keep your banjo bolt from your old calipers. the new ones dont have those. we had to make 2 trips back to autozone becuase of that shit lol.

THEMkris · 12-06-2007, 09:53 PM

banjo bolt????

aznpoopy · 12-06-2007, 11:34 PM

no doubt the bolt that holds the brake line to the caliper

honestly i don't remember it being a banjo bolt, but i haven't touched my rear brake lines in at least a year

THEMkris · 12-07-2007, 01:02 AM

lol yea i just figured that out now. anyone else have rear calipers for sale?

motorsnail · 12-07-2007, 01:45 AM

Might wanna make sure you didnt put the brake pads on ass backwards

sounds stupid but a friend did it on his civic and it was making a grinding noise saying the same thing "Dude its the new brake pads, I think they gotta brake in" RRRR wrong seems as if the pads dont like going the other way on the rotor and chewed its way threw it. Its like a ginda grinding/rattle noise. I would compare the noise to scrappy a needle on a pan.

THEMkris · 12-07-2007, 01:52 AM

backwards??? as in the shims facing the rotor?? well noo..

but putting them the other way wouldnt work either. the hawk pads have two "studs" on the back of two pads. they wouldnt let me install them backwards cause the caliper wouldnt go on all the way. so there was basically only one way to put them
