Another common problem that crops up with disc brakes is rusting caliper
slides and pins. Rust prevents the calipers from sliding back and forth when the
brakes are applied. When a caliper sticks in the applied position, the pads wear
out prematurely. Keep the slides and pins cleaned and lubricated.
A rubber dust boot protects the pistons within the brake caliper from road dirt
and grime, as well as weather elements. If the boot tears, then grime can
accumulate and cause the piston to become stuck. This causes the brake to stay
applied after releasing the brake pedal, resulting in premature brake pad failure.
Have your brakes checked when you have your tires rotated every 6,000 miles or
every other oil change. The technician will be able to see if a boot is broken.
On cars equipped with four-wheel disc brakes, the emergency brake cables
must be kept free and moving. Why? Because it is the emergency brake cable
that activates the e-brake. If the cable freezes up due to rust or fraying, when you
apply the emergency brake it will not release. A frozen e-brake causes the brake
pads to heat up and wear out. It will also cause the rotors to warp from the
intense heat generated from friction.
