Upgrade your braking system with this high-performance brake master cylinder, designed for vehicles with a brake servo and brake light switch mounted on the cylinder. Featuring a larger 23mm bore (compared to the standard 19mm), it enhances pedal pressure and feel, making it ideal for cars fitted with larger-than-stock brakes. 

Built to OE specifications, this master cylinder offers precise fitment and reliable performance. The high-quality cast iron construction ensures durability, while EPDM piston seals resist corrosion from glycol-based brake fluid. Protect your vehicle from potential brake failure and fluid leaks—replace your old master cylinder today with confidence, backed by a 24-month unlimited mileage warranty.
