130.62023 Brake Master Cylinder for Chevrolet

130.62023 Brake Master Cylinder For Chevrolet adopts cast iron casting process, the master cylinder diameter is 28.575mm (1.125 inches), and it can withstand 32MPa hydraulic pressure. The master cylinder adopts a dual-chamber series structure design, equipped with a compensation hole and a fast filling valve to ensure the stable flow of brake fluid under continuous braking conditions. Its friction coefficient is stable in the range of 0.38-0.42, which is especially optimized for the front wheel disc brake system.

In terms of engineering design, the 130.62023 master cylinder adopts the original aluminum casting process, and the piston sealing system is equipped with high-temperature resistant fluororubber material, with an operating temperature range of -40℃ to 180℃. Its brake fluid storage tank capacity is 350ml, equipped with an integrated float switch, which can monitor the liquid level status in real time. In response to the maintenance needs of classic models, the threaded interface specifications adopt a 1/2"-20 inverted design for the front left port and a 9/16"-18 inverted structure for the rear port to ensure seamless connection with the original vehicle brake line.

During maintenance practice, it is recommended to check the working condition of the master cylinder every 80,000 kilometers or after 5 years of use. If the scratch depth on the inner wall of the master cylinder exceeds 0.1mm or the elastic loss of the sealing ring exceeds 30%, the assembly needs to be replaced directly. During installation, pay attention to the torque value of the oil pipe interface (18-22N·m for the front port and 20-24N·m for the rear port), and use the two-stage pressure emptying method to completely remove system bubbles.
