How to remove and install a master cylinder on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

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.

GMC Sierra Brake Master Cylinder

The Brake Master Cylinder in GMC Sierra cars is one of the essential sections involved in the braking process, which every automotive manufacturer must consider; it translates the force applied on the brake pedal into hydraulic pressure to move slave cylinders. Force and displacement are improved in this system through the use of hydraulic fluid that transmits force from the master cylinder's piston to slave cylinders. GMC Sierra vehicles commonly incorporate dual circuit master cylinders with two piston; it is a standard as this guarantees that in case the hydraulic procedure fails in one circuit, the remaining procession could offer pressure adequate enough to halt the Sierra vehicle. It is involved in applying pressure on some calipers or on the drum brake hence applying friction to stop the wheels, and in actuating the slave cylinder for the disengagement of the clutch. The Brake Master Cylinder regulates the hydraulic force and assists in the distribution of pressure thereby enhancing the efficiency of the vehicle's braking and clutch.

Each OEM GMC Sierra 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.
