Caliper Pistons & Repair Kits FAQs

Can a brake caliper be rebuilt?

Yes, in many cases. If the caliper body is in good condition, a repair kit can replace the seals, dust boots and sometimes the piston, so the caliper works like new again.

What's in a caliper repair kit?

It depends on the kit. Most include piston seals and dust boots, and some include new pistons or slide pin boots. Check the listing to see exactly what's included.

When should I rebuild a caliper rather than replace it?

A rebuild suits a caliper with a sound body and bore that has worn seals or a sticking piston. If the bore is pitted or corroded, or the caliper is cracked or damaged, replacement is the safer option.

Do I need special tools to rebuild a caliper?

Usually you'll need basic hand tools, brake cleaner, assembly lubricant, and a way to remove the piston safely. Work carefully, keep everything clean, and follow your vehicle's workshop manual.

Do I need to bleed the brakes after rebuilding a caliper?

Yes. Opening the hydraulic system lets air in, so the brakes must be bled to restore a firm pedal before the car is driven.
