BRAKE NOISE TROUBLESHOOTING
Dirt or dust buildup on the brake pads and disc is the
most common cause of brake noise (squeal caused by
vibration). If cleaning does not reduce the occurrence of
brake noise, Permatex™ Disc Brake Quiet can be
applied to the back of the pads. Follow directions on the
package. This will keep pads in contact with caliper
piston(s) to reduce the chance of squeaks caused by dirt
or dust.
