Bleeding brakes?

[Monopoly]

hey i put on new front rotors and pads and now the brake pedal wont pump even if the cars on...guessing i'll need to bleed the brakes so what nut do you loosen off to bleed the brakes???

You're looking for a 'nipple' that's located on the top of the caliper, on the back side. I should have a little black rubber stopper on top of it, to protect from corrosion.
You can see it in this picture, jutting out from the backside of the caliper...

Here's a picture of what the whole thing would look like if you removed it.

ok i bled the brakes and now the brake pedal is still spongy!!! wtf s going on!?!?

i tried bleeding with the car off and on, i tried bleed with the brake fluid cap off then on and still spongy!!!

i dont know what the hells going on!!! shit i might of shot the master cylinder u think???

Just curious how you bled the brakes. I don't want to assume anything. Did you do them yourself, did you have someone else help you, did you use one of those one man bleed kits??

As DSM Power made mention, the speedbleeders are great for doing it yourself, although I'm always at the brake checking for bubbles while some poor sucker gets to pump the brake pedal. :D

haha yeah i had a buddy pump hte brakes while i loosened off the bleeder nipple

a friend of mine said maybe try bleeding the other Nipple on the caliper??? he said that if there 4 piston calipers they should have 2 bleeder nipples???

also to try and bleed the ABS as well...i'll try it out tommorow

fucking brakes feel awesome now! air mudt of got into the caliper

only one prob, they squeak like a bitch even when i apply the brakes the noise doesnt change...

i thought mayeb i bent the backing plate so i tried bending it back but still squeakin like mad

the only time it doesnt squeak is when i accelerate. Maybe i didnt bend it back far enough...if not the plate what else could it be?:confused:

My old pads were also squeaking and they were new. It ended up that the brake materiel wasn’t glued right on the metal plate and it created a vibration (squeak). When I did remove them I could see a little gap where they weren’t glued. Installed a new set and the problem was fix.

-i just checked the pads they look flawless.
-i checked the pins they are perfectly straight no worries there.
-i measured the backing plate on the drivers side and bent it exactly to the same distance from the rotor on the passenger side using my Vernier.
-the shims were a little bent around the edges so i hammered them flat.
-i scrubbed the pistons in the calipers with a wire brush really thourough this time.
-i soaked everything down in brake cleaner as well...

havnt test driven it yet its still jacked up w/no wheels on it yet. somehow i have a feeling its still gunna squeak!...

remember it only squeals on passenger side front, and ONLY goes away when i accelerate...when i brake hard or soft it doesnt make any difference in sound. it sounds the same when driving at a constant speed.
FUCK this is pissin me hardcore!:finger: :angry: :angry:

What kind of brakes pads did you put it? Stock or aftermarket? I've heard that Stillen's have a reputation for squealing, right memystealthandi???? :(

[Monopoly]

just factory pads and rotors form dealership.
o and i bled the brakes to much the fluid is now 100% brand new and its topped up:D

i doubt it would be the pads cause they squeal whether or not i brake

[Malice]

How much adhesive did you put between the pads and the caliper?

[Monopoly]

adhesive? u mean silicone?
i only put a little bit..think i should add some more?

[Malice]

Adhesive, silicone same thing.

I always use a decent amount when I change pads. It is fairly cheap so I figure a good coverage can't hurt. I have never had a brake squeek on any job I have done.

[Monopoly]

I'LL give that a try and see what happens.

thanks!

ok its not the brakes making the noise!
sounds like the rubber of the tire rubbing against something...i dont know what i did!
