Genuine GMC Envoy Brake Master Cylinder

Brake Master Cylinder in GMC Envoy is one of the main parts of the brake system which make the change of force applied by foot to hydraulic pressure to operate the brake. Usually made of cast iron or aluminium, it consists of pistons, seals, and springs, all fitted in a bore. The fluid reservoir is usually nylon or plastic and bolts onto the top of the master cylinder body and are sealed with O-rings. In GMC Envoy models, the Brake Master Cylinder is additionally mounted at the front side of the vacuum power booster. When the brake pedal is pressed, the pushrod exerts pressure on the pistons and it in turns compresses the brake fluid. A return spring on release shifts the pistons in a backward direction thus allowing the provision of the fluid. Since 1967 there have been dual circuit master cylinders with two pistons in order to separate the failure in one hydraulic system. As the years pass by, it is common for the Brake Master Cylinder to show signs of leaks, and internal brake failure brought by corrosion or seal problem. Some of the preventive measures which should be taken include: The practice of routine check up of the hydraulic system for fluid leaks and ensuring that the system has no moisture content is prudent. To appropriately control hydraulic force and pressure application, the GMC Envoy's Brake Master Cylinder is a system required for stable and secure braking.
