Wilwood 200-1119 – 2.38" Stainless Brake Caliper Piston

Wilwood 200-1119 – 2.38" Stainless Cup Brake Caliper Piston

The Wilwood 200-6633 Stainless Cup Caliper Piston is engineered for high-load racing brake systems where durability, thermal control, and consistent performance are critical. Manufactured using Wilwood’s proprietary stainless stamping process, this piston resists deformation and prevents “oil canning” under extreme hydraulic pressure.

The thin-wall cup design provides low thermal conductivity, minimizing heat transfer from the brake pads into the caliper body, seals, and brake fluid. Constructed from a high-strength proprietary stainless steel alloy and finished with a bright machined surface, this piston ensures smooth operation, proper sealing, and long service life in demanding race environments.
