Brake Caliper Rebuild

A caliper rebuild replaces the seals, dust boots and sometimes the pistons of a brake caliper.

What is Brake Caliper Rebuild?

It can fix sticking or leaking calipers. Repair kits are available for many calipers. Exchange reconditioned calipers are a common alternative. Pistons with chrome damage or rust should also be replaced. A sticking caliper often causes a burning smell and a hot wheel after driving.

How it works

New seals and boots restore smooth piston movement and keep fluid in and dirt out.

Why it matters for your car

Bleed the brakes thoroughly after rebuilding. Calipers with pitted or corroded bores should be replaced, not rebuilt.
