GMC Yukon Brake Master Cylinder

The Brake Master Cylinder as a part of GMC Yukon automobiles plays the role of halting the car and transforming the force applied by the foot to hydraulic pressure. This hydraulic pressure is taken to the slave cylinders where it in turns activates the push rods which apply the brakes exerting the required friction to halt the automobile. Usually, the GMC Yukon is equipped with a dual circuit master cylinder and that is why even in case of a malfunction of one circuit, there will be enough force to break. Since the inception of the product, GMC has used both cast iron and aluminum Brake Master Cylinder housings; the reservoirs, however, are either integral or externally mounted depending on the model. The currents integral reservoirs contain one threaded cap, while the external ones may contain one or two caps at most. In any case, the construction of the master cylinder does not differ; thus, the brake performance for the GMC Yukon will not be compromised. It is also important to regularly service the system since leaks and internal flaws will adversely affect the outcome of braking.

Each OEM GMC Yukon Brake Master Cylinder we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

Q: How to remove and install a master cylinder on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: To remove the brake master cylinder, first disconnect the cable from the negative battery terminal and unplug the electrical connector for the fluid level warning switch. Remove as much fluid as possible from the reservoir and prepare caps or plastic bags to cover the ends of the lines once they're disconnected. Loosen the fittings at the ends of the Brake Lines where they enter the brake master cylinder and pull the brake lines away from the brake master cylinder, plugging the ends to prevent contamination. Remove the nuts attaching the brake master cylinder to the power booster and pull the brake master cylinder off the studs. To install the new brake master cylinder, bench bleed it before installing it by mounting it in a vise and attaching a pair of brake master cylinder bleeder tubes to the outlet ports. Fill the reservoir with brake fluid of the recommended type and slowly push the pistons into the brake master cylinder until no more air bubbles are present. Remove the bleed tubes and install plugs in the open ports to prevent fluid leakage and air from entering. Replace the o-ring seal on the end of the brake master cylinder and install it to the booster, leaving the mounting nuts finger tight for now. Thread the brake line fittings into the brake master cylinder and tighten the mounting nuts to the torque specifications. Fill the brake master cylinder reservoir with fluid, then bleed the lines at the brake master cylinder, followed by bleeding the remainder of the brake system. Confirm that the brakes are fully operational before resuming normal driving.
