Wilwood Disc Brake Caliper Piston Stainless Steel

Wilwood stainless steel disc brake caliper pistons are replacement pistons for Wilwood brake calipers. They are also known as brake caliper pistons or caliper pucks. Each piston transfers hydraulic pressure from the master cylinder to the brake pad, so the pad clamps against the rotor when you press the pedal.

Key Features:

• Stainless steel construction: Resists corrosion and wear, and stays durable under repeated heavy braking.
• Low heat transfer: Stainless steel conducts heat less readily than aluminum or steel. This helps keep heat from passing into the brake fluid, which reduces the risk of fluid fade and vapor lock.
• Precision-machined design: Built to fit Wilwood caliper bores for smooth, consistent piston movement.
• Service replacement: Suited to caliper rebuilds and to replacing pistons that are worn, pitted, or corroded.
• Racing and performance use: Wilwood designs its brake components for street performance, track, and competition use.

Pistons are available in several diameter and length configurations, each under its own part number. Choose the piston that matches your Wilwood caliper. Replace seals and other wear items during a rebuild to restore dependable braking performance.
