Title: Front left brake still sticking after replacement
Post by: madsb on 27 November 2013, 17:45
My old discs were warped from the front left brake sticking. Mechanic replaced discs and pads on both sides in the front and the front left caliper. However, the stupid left brake is still sticking! On a straight road, car will go left after a while if I let go off the wheel - it's more noticable at higher speeds on the highway etc. Also, the wheels correct themselves faster coming out of a right turn compared to a left.

Mechanic is puzzled and suggests a brake fluid change and hose change on the left..

Any ideas???
Cheers.

Is the wheel getting warm from the caliper binding? Also you'd normally notice more brake dust build up on a wheel with a sticky caliper.

One other point, is your tracking ok?

@xion: Yes, as it says in post :)
@Therusterman: The left brake disc gets hotter than the right one, hence why I still believe this is a brake that sticks and that the tracking is not an issue.. But I should probably ask him to check that aswell.

If they are non genuine pads it is possible the metal anti squeal shim has not been bonded in the correct position and can rub on the calliper causing the pads to stick.
Also you could have rust on the piston causing it to drag when returning but I would of thought that would of been checked when the mechanic changed your pads and discs.
Hope this helps

Re read your original message
Rubber brake pipes can swell up in side causing fluid to travel ok when pressurised but restrict return flow.
If that's the cause I would change all the pipes.

Thank you for the input guys. Don't think it is the metal shim, as I'm sure it would have been worse then and possibly audible. Will ask him about rust on the piston and have him change the hoses :)

Jack the car up and spin both front wheels, you will notice if caliper is sticking.
Another thing to note is, if the wheel is getting hot, I'm sure that could be down to wheel bearing too.

Well if the caliper is still sticking then check the slide pins.

it could be the other calliper that's sticking off not the new 1 that's sticking on. I would get it on a brake tester.

Had the hose changed but no difference.. So what could it be? : Slide pins, rust on piston and bad tracking?.. Thinking the latter is more likely, as I assume the mechanic has checked the two first things.. Any input?

get it to an m.o.t place and get the brakes rolling tested, this will tell you what both sides are doing effort wise (and brake balance)

that will/should tell you if it's a brake issue.
Have you checked the rear brakes?? (these are more prone to sticking)
