Default HELP! Brake Question

I just finished painting my calipers tonight (Folia Tec red) :cool: Way Cool! After re-assembling the brakes and taking the car for a test drive(also got new tires while the rims were off) I noticed a squeek from my brakes. :mad When I press the brake pedal, while at a complete stop, they squeek. It seems to be mainly the rears but the fronts as well some times. There is also a ticking coming from the pass. rear under Med. to Heavy braking, but it has always done that. :eek: :mad :confused:

Please, any suggestions would be greatly appriciated.
Thanks in advance,
Matt

I was planning on driving this car to Bowling Green on Friday and don't want it to squeek the whole way.
Maybe I should re grease the caliper pins?

My guess would go along with yours. If the squeeking is happening only when stopped, it is probably the caliper sliders rubbing inside the bridge. Pull the calipers and rub silicone grease on the slider pins and re install. Make sure the rubber boots are properly installed to keep garbage out. Might make sense to use a little silicone on the pad/bridge contact points also. Hope that this helps.

Did you put any anti-squeal on the new pads? I'd recommend the permatex blue spray stuff.

As to the "ticking," could you elaborate that a bit? It could be something as simple as a burr hitting a specific point on the pad to a wheel bearing going bad. Or it could be your parking brake shoe contacting the inner part of your rotor. Or it could be something separate from your brakes. Does the ticking speed up and slow down with the car, or is it constant? Is it a metallic clicking type sound? etc.

GOOD NEWS! The squeeking is gone! :D :D It was coming from the point where the top of the pad touches the "spring clip?" on the bridge of the caliper. Any one who does their brakes should make sure and apply a thin layer of grease to this point. Also make sure to pull the slide pins out, clean them, and repack with grease.

lyonsh: I don't think that the clicking is a wheel bearing. Your idea of the parking brake coming in contact with the rotor sounds very plausable. while breaking the clicking slows as the car does. If the parking brake was contacting the rotor during braking and "repeatidly sp?" binding and poping back, this would cause the sound I am describing. Two questions:
1. Why only durring braking?
2. how to adjust the parking brake properly. I tightened the adjuster wheel while I was doing the above things and now have a woking parking brake. :D FOR THE FIRST TIME :( My local dealer actually told me there was no way to adjust it and that I just have to leave it in gear :mad ) Also Why would I have had this clicking before adjusting it as the pads were no where near the drum?

A big THANKS to anyone with suggestions and to thoes who have already posted. :cheers: :cheers:

Glad to hear you got the squeak fixed. :yesnod:

As to your questions:

You may have over-adjusted the parking brake a bit. If so, the pad could be dragging slightly. On drum type brakes, when you put the brake on the direction of the applied force actually provides what's called "self-actuation" force on the shoe. It increases the contact force between shoe and "drum." In theory, this wouldn't be the case on a parking brake, but shoes is shoes and force is force, so it's possible, and would explain why you only hear it during braking.

I'd suggest backing off the p-brake adjustment a few stops and see if that fixes it. You've actually got a decent range of motion with the p-brake handle, so the shoes don't actually need to be right up against the drum part of the rear rotors.

Let us know if that works. :cheers:
