I recently had all the brakes replaced on my explorer, roughly around 70K, with ceramic pads. Now when I step on the petal, sounds like the rear brakes are squeaking. It happens when I first step on the pedal. If I press hard or push further on the petal the noise stops but will start again if I let up on the brakes. I took it back and the shop said it was probably dust. So they took compressed air and cleaned em but I still have it. Any suggestions on what to do to get them quiet?

Thanks in advance..

they make stuff to put on rotors to stop squeek, try your local parts store.

 

These noises are usually the result of the brake pads vibrating. There are several reasons why brakes can vibrate. Problems include worn pads; wrong pads have been installed, glazing to the pad or rotor friction faces. In some cases, warped rotor, misaligned or loose calipers, even loose wheel bearing, or sticky pistons can lead to braking noises.

The first step in silencing noisy brakes is to do a complete inspection of the braking system to identify the source of the problem. Check for excessively thin brake pads scored or warped rotors, brake fluid leaks and oil or grease on pads. In your case, since you just had a new system installed, this is most likely not the cause.


Make sure pads and shoes have not worn down to the metal backing plate. Look for rust or corrosion that can prevent proper functioning such as a piston sticking in its cylinder(s). Check pads and shoes for equal side-to-side wear to determine if a piston might be sticking leading to unequal wear.


Often the braking system checks out okay, but squealing persists. While probably not affecting braking safety and effectiveness, the noise can be irritating. If the squeal comes just as you about to come to a complete stop, often the reason is a brake pad that is vibrating against the rotor's friction faces or caliper.

One solution here is to install vibration dampeners. These are made of a self-stick fiber material, which adheres to the back of the brake pad backing plate to dampen brake pad vibration.

Another solution is to coat the back of the brake pads with an anti-squeal compound, a thick heat-resistant polymer adhesive applied to the back of the pad to provide a cushion between the pad and piston as well as help the pad retract with the piston.

This material comes as an aerosol spray or as a liquid. Coat only the area that contacts the piston, making sure that it does not get onto the front, contact area of the pad or rotor. Here is a link to this type of product. http://www.international-auto.com/index.cfm/fa/p/pid/2764/sc/8140

 

ok, thanks I'll check it out.
