Find Replacement Brake Calipers

The brake caliper is a hydraulic component in the disc brake system, and is made up of the caliper body, a brake caliper piston and seal, and a bleeder valve to allow the brakes to be bled. Brake calipers use fluid pressure from the brake master cylinder to compress the brake pads against the rotor surface and maintain the friction necessary to stop your vehicle. Over time, brake calipers may develop leaks from the piston seal, or the piston inside the caliper may stick. This can cause your brake pads to be in constant contact with the rotor and may result in uneven or premature brake pad or rotor wear. If only one brake caliper is sticking, this may cause your vehicle to pull to one side, squeal, or make rubbing noises when braking. If the caliper is leaking and enough brake fluid leaks from the piston seal, your brakes may even stop working entirely. It is important to always inspect the brake calipers, as well as the brake caliper bracket and guide pins, when you perform brake pad and rotor service. If the caliper is leaking, or if the piston is stuck or noticeably damaged, the brake caliper should be replaced to ensure you can continue to drive and brake safely.
