Man i installed a cnc brakes hydraulic ebrake in my car, plus new rear rotors and hawk pads.
I have bled each side 50 plus times, problem is that i have to pull it with pretty much both hands to get it to lock while going in a straight line.
Could it be the wheels? they are heavy work meisters 18 by 11 with bald 275s on the back?
This is driving me crazy!!!! Help!!!

ABS still hooked up by any chance? Buddy of mine installed PBM kit and brakes wouldnt look up, it wa because the ABS was engaging preventing lock. His handle wasn't as hard as your saying yours is though.

no abs is long gone, i mean if i get the car side ways mid drift it will lock like its supposed to but say i want to do an high speed initiation, all it does is slow the car unless i let go of the wheel and pull it with both hands.
I have noticed if i put my foot on the regular brakes a little bit the ebrake locks way harder.

I barely have to touch mine. I should take a video. In a straight line I have to pull it kinda hard, but as an initiation I only use 2 fingers. 17x10 with 235s

Try running smaller width tires, and a high PSI. Or just tap the brake when you pull the ebrake handle, if its working, why change it

well i just installed it, the way i see it this is not workinng properly, being that a stock cable ebrake will lock the tires at 80mph, i dont understand what the hell is wrong with this thing.

it does work how I made this... It was that my line was kinked causing no fluid... But anyhow is this how it ebrake set up is? Mine works! Follow the diagram

thats exactly how mine is setup.
How much free play is in yours ?

I would say almost none... Before I bleed it it has plenty of play is ur lever going down? Does it stay up by itself?
gsracer

it stays up by itself, like i posted above if you give the footbrake a bit of pressure at the same time as pulling the ebrake, the handle gets hard and then locks fairly easyily.

My corolla was like this too. A friend suggested I install a proportioning valve. That was it, after that it worked fine. Haven't had one on a 240 though so I can't say for sure. The added capacity to the brake fluid is what messed mine up. Even my brakes were softer before I installed the valve.

well i figured a few things out and will be doing a custom wilwood setup, the cnc doesnt have the balls to lock up the rears with big tires at high speeds without working the front brake at low speeds <50mph it works great, but i want it for the high speed stuff.

Did you try to switch the lines on the brake itself (from bmc and to rear) They are probably backwards... There are two styles of cnc hydro brakes I have seen and they hook up backwards from each other.
Chances are they are backwards if you haven't tried swapping them it is worth a shot. Mine locks up my Nitto555 275 with my pinky finger at 60mph with ease.

yep i switched the lines way in the beginning just to be sure.

I'm having the same problem! I'm running a CNC E Brake with Brembo rear brakes. It shouldn't have any problem locking. I just bled my system, AGAIN.
Would playing with the adjust lock nut on the cylinder help possibly? I'm running 18x10.5 with a 255, straight line is damn near impossible to lock up, turning it'll chirp the tires but no serious lock. In order to get that chirp I had to push the lever HARD. I have an event Saturday I'd like to get this thing working...

hmmm...
you shouldn't have to pull it very hard, i ran 18x11 weds kranzes with 275/35 toyo t1r's on them and entering a large turn in 4th maybe 160-170 and i would clutch in and yank it not very hard, no muscle effort at all really and im pretty skinny

I didn't try locking it up with added pressure from the footbrake, though. I just came home from driving it and looked this up. I'll try that tommorow. Maybe it'll lock better on the 235's at the event
It's probably too large of a MC or too low of a lever ratio so you can't generate enough force with your hand to lock up the rear wheels. A smaller MC or a higher lever ratio will trade more travel on the lever for more brake line pressure.

kinda bump from the dead but i've just installed a cnc and a pbm hydro setup (on different cars) both of these have the same problems like listed, hey both dont seem to help any, infact they take more effort then the factory handle. Did anyone resolve this issue? I'm planning to call pbm tomorrow and ask, so far it's a waste of time

I found same thing- hard to lock rear in a straight line.
however, with just a slight weight transfer to the front, it locks super easy.
i have to give it a quick stab of foot brake before i pull the hand brake, but with that done, it locks just fine.

How many of you are running ABS with your hydro setups?
I have a RPS13 with ABS and want to run a hyrdro ebrake kit.
Will this still work?
i think it should work and you can get used to it after a time...but if you're putting a hydro ebrake in your car you're not going to drive like a daily mommy or? so get the abs out to have real fun;)

03-16-2011, 10:52 PM
I'd really like to get the ABS out but i hear its quite the job to do, dont suppose there are any kits out there to buy to delete it?
whats so difficult? get a non abs master in there and customize you pipes a bit, finish.
maybe won't look too nice if u do pipes first time but that should be all...
google there're alot of diy's around how to remove abs;)

I cannot get my stock ebrake to lock up the wheels no matter the speed in a straight line. I have brand new rear rotors and pads but I have fresh 275's in the rear. I was able to get it to lock them up with ease when I had 235's on the back though.

Has anyone resolved this issue?
I'm having the same exact problem with my hydro ebrake. I have to pull the ebrake handle with pretty much both hands very forcefully while going in a straight line, and even then, it barely locks. The ebrake handle only travels about an inch.
Friends have helped me bleed the system over and over and over again, still same issue.
I tried switching the brake lines on the hydro and all it did was pushed fluid into the master brake cylinder reservoir. I so switched the lines back the way it was.
Any help?

Your e brake cables are stretched
rb25_s13*CHUKI
08-09-2012, 12:25 PM
either get new cables or get a hydro ebrake setup

Also some good brake pads would help out alot, get the hawk hp+ brake pads, that have a good bite to them!

what size master cylinder on the hydo?
whats the bore size on the rear pistons?
how long is the handle on your hydro?
I have the same problem with my E36, ASD pass through set-up, connecting to rear brake lines. The pull was Rock hard, and it only moved 1/2 an inch. I increased the size of the leaver, it helps a lot, locks the rears instantly

It's a stock S13 master cylinder, K-sport standard hydro 5/8", rear brakes are stock S13 with less than 1 year old brake discs & pads.

I'm using 3/4" Wilwood cyl
Stock s13 calipers, Shitty autozone pads
Handle is about 16" +/-
Locks super easy, good amount of travel on teh handle as well. Locks at 5mph to ---mph, straight line, no problem.
I think it has alot to do with the way the leverage point is.

I see this A LOT.
I have ASD 16" pull back. dual z32.
USE CHEAP PADS. seriously go to the autoparts store and buy the cheapest of the cheap pads!! i promise!
Ceramics and ebrakes DONT WORK.
gsracer.. saw you at CFRC couple weeks ago. SICK. you were entering silly fast by the end of the night!

looks custom. you can get a similar one assembled and ready to go from ASD motorsports for 180. its pretty amazing. this is the standalone master version
