Brake caliper

The brake caliper is an important part of the braking system. The brake pads are located in the caliper and are "clamped" by the caliper piston. The piston is driven by the brake fluid and presses the brake pads against the brake disc.

The brake caliper must always be in good condition and must not leak. If you want to repair the caliper on a small budget, you can use one of the many caliper repair kits from major brands like Brembo, AJP, Nissin, etc.

Racing caliper

After tuning measures, where the performance of a motorcycle is increased, the brakes must also be readjusted. You can install oversize kits instead of the original brake discs, or use racing calipers with multiple or larger pistons. Some tuning calipers are made of materials that allow better heat dissipation.

Especially for enduro and motocross bikes, there are various caliper upgrade kits. There are also complete brake kits with brake disc, brake pads, caliper, brake line and brake master cylinder.
For 50cc scooters and motorcycles, we offer 2-piston calipers that considerably improve braking performance. Most calipers are universal and are adapted to a specific vehicle via a brake caliper adapter.

Changing a brake caliper

To install a brake caliper, you need relatively few tools. However, you should make sure that the copper washers on the banjo bolt that holds the brake hose are in perfect condition so that no fluid can leak out.
You'll also need new brake fluid, as you'll need to bleed the brake system. You must remove all air bubbles from the system; you can bleed manually or with a special brake bleeder.
