My brakes make a rotational squeaking noise...?

Question

Can anyone suggest whats wrong?
When I was accelarating and braking I kept getting quite a bad shudder in the wheel and peddles and I found out that my tracking was out by quite a bit on my car. I had to buy new front tyres and I also needed new brakes so I got them fitted at the same time (discs and pads).
A week later I have found that whilst my accelaration and braking shudder has reduced dramatically, I can now hear a squeaking in my front brakes when I brake. Its not a constant sound, its rotational - if you know what I mean!

Does anyone have any ideas??

Answer 1

Take you car back to where the brakes were replaced and ask them to check them out. An overlooked task while doing brakes is to put a light coat of brake part lube on all the contact points like the caliper bolts and back of the brake pads that touch the caliper that squeezes the pads against the discs. :Have them also check the discs to make sure they are not warped. It is easy to warp them when the lug nuts for the tires are tightened too much or not in a crossing sequence that can make the brakes squeal rotationally or go squeak squeak squeak instead of sqeaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaak hope this helps

Answer 2

You have a brake rotor problem. There are 2 things to consider here:

When you get a brake job done the rotors can only be used up until a certain point before they need to be replaced. Even if you resurface them, they could be well within specs as it relates to thickness but the only way to eliminate the squeaking is to replace them.

Secondly, when the rotors are resurfaced, this process should be done while the rotor is still on the car. Many shops still have the old fashioned equipment where they remove the rotor and put it on a machine to resurface it. Because the rotor does not go back on the car the exact same way every time there could be some degree of misalignment even if its as much as a hundredth of an inch. When the rotor is resurfaced on the car, its perfectly aligned because even though the rotor itself may "wobble" a little bit, the surface will be exactly aligned with the brake pad.

Brake squeal is a common problem and since the brakes have just been changed it is most likely due to the type of pads used and there's not much that will help the problem except getting a better quality pad put on your car. You can try cleaning the pads and discs using a can of brake cleaner. Simply spray the pads and disc throughly. It is best done with the tire off, but just to see if it helps you can try it with the tires still mounted.

Perhaps on the your brake pads isnt seated in right or the caliper was not put on correctly. Take it back where you had the repairs done and tell them to fix it correctly. They shouldnt charge you anything and if they do get the phone book out and call the District office ( the big guys) and they should get everything in order for you without charge.

Answer 5

Before you do anything drastic, just jack up the car, remove the wheel, and then just put it back on. I've seen this problem before many times. The bozo that put your wheel on at the shop tightened each lug nut all the way one-at-a-time out of laziness and sloppiness.

After putting the wheel back on, put on and tighten every other lug nut by hand. This distributes the load uniformly. Most cars have 5 lug nuts per wheel so eventually you will get to each nut. Then tighten every other nut with the lug wrench snugly. Lower the car and firm up every other nut.

If the problem does not go away, the bozos at the shop did not reinstall your anti-squeal plates out of laziness and sloppiness. Or they installed them backwards.

If so, go back to the shop and threaten suit.

Answer 6

if you take your front wheel of your car you will see a metal plate behind your brake disc whats likely to of happened is the new discs are slightl wider so you will have to bend the metal plate away from the discs slightly. the metal plate is only there to stop the gravel from the roads going onto the pads.

Breakpads need to bed in when new,give it a bit more time.
