20759706 Brake Master Cylinder for Chevrolet Cadillac

The Chevrolet Cadillac 20759706 brake master cylinder is a core hydraulic brake component certified by GM. It is designed for high-performance SUVs and pickup trucks. As the pressure conversion center of the hydraulic brake system, its core function is to accurately convert the driver's pedal force into hydraulic energy, and achieve balanced distribution of front and rear wheel braking force through a dual-chamber series structure. The master cylinder adopts a high-strength aluminum alloy casting process, and the master cylinder diameter specifications are 13/16 inches (front chamber) and 21/32 inches (rear chamber), which can withstand 32MPa hydraulic pressure.

The 20759706 Brake Master Cylinder For Chevrolet Cadillac uses a dual-piston compensation valve structure and is equipped with a fast filling valve technology to ensure hydraulic stability under extreme working conditions. Its piston sealing system is made of high-temperature resistant fluororubber (in compliance with HG2865 standard), with a temperature range of -40°C to 180°C. It is equipped with EPDM rubber sealing components to effectively resist brake fluid corrosion.

As a GM original certified part (OE number 20759706), the master cylinder has passed the TS16949 quality management system certification, and the production process uses the same casting mold and assembly process as the original Cadillac Escalade. Special environmental tests show that the hydraulic response delay at -40°C is less than 0.2 seconds, and the liquid temperature rise is controlled within 15°C after 50 consecutive brakings in desert conditions.
