Caliper Rebuild Kits

Caliper Rebuild Kits: bring a sticking or leaking caliper back to service

Caliper rebuild kits are the seals, pistons, boots and dust hardware that let you refresh a caliper instead of replacing it. Over time the square-cut seals harden, the piston bores corrode, and the dust boots tear and let grit in. That is what causes a caliper to drag, a pad to wear unevenly, or brake fluid to weep past the piston. Splitting the caliper, cleaning the bore, and fitting fresh seals from one of these kits restores clean piston travel and a firm pedal for a fraction of the cost of a new caliper.

What we stock

There are 43 kits in this category from 4 brands: Bikers Choice (14 in the range), All Balls Racing (13), GiroDisc (11), and Wilwood (5). Current in-stock pricing runs from $28 to $131, which is the live range for what is on the shelf now rather than a fixed price.

Coverage leans heavily toward motorcycles and sport cars. Of the kits with fitment listed, top makes include Harley-Davidson, Honda, BMW, Porsche, Suzuki, Ford, Subaru, Audi and Kawasaki, across a year span of 1972 to 2023. Concrete examples span both worlds: the All Balls Racing CB600F Hornet front kit at $54.99 and the GL500 Silver Wing front kit for older Hondas, the Bikers Choice 4-piston kit and the piston and seal kit for Bikers Choice billet calipers, plus the GiroDisc 911 Carrera PCCB front kit and the RS3 Sedan front kit at the top of the range.

How to choose

A rebuild kit is vehicle- and caliper-specific, so the first filter is what caliper you actually have, not price. Bikers Choice and All Balls Racing kits cover the bulk of the motorcycle applications here, including Harley-Davidson XL, FX, Sportster and FL families and Honda and Suzuki sport bikes. GiroDisc kits target specific performance-car calipers such as Porsche and Audi applications. Note that some kits are piston-and-seal kits and others are seal-only, and some are labeled front-specific, so read the title against your setup before buying. If your caliper bore is pitted rather than just worn, a rebuild will not save it and you should look at a replacement brake caliper instead.

What else you need with it

Plan the whole job while the caliper is off. Fresh brake pads and brake rotors make sense if either is near the end, and mounting hardware keeps everything torqued correctly. If your lines are old, look at brake lines, and a soft pedal after the rebuild can point back to the master cylinder. For a bigger step up rather than a refresh, the brake upgrade kits section is the place to start. Everything sits under the main Brakes section.

Fitment and ordering
