How to remove and install a wheel cylinder on GMC Sierra?

To remove and install a wheel cylinder, first raise the rear of the vehicle and support it securely on jackstands, and block the front wheels to prevent rolling. Remove the brake shoe assembly and all dirt and foreign material from around the wheel cylinder. Using a flare-nut wrench, unscrew the brake line fitting from the wheel cylinder, being careful not to pull the line away from the cylinder. Remove the wheel cylinder mounting bolts and detach the cylinder from the brake backing plate. To install, place the wheel cylinder in position and connect the brake line fitting, being careful not to cross-thread it. Install the mounting bolts and tighten them to the torque specifications, then tighten the brake line fitting securely. Install and adjust the brake shoes, bleed the brakes, and confirm that the brakes are fully operational before resuming normal driving.

GMC Sierra Wheel Cylinder

The GMC Sierra Wheel Cylinder provides the hydraulic force that applies the rear brake shoes to the drum while offering reliable stopping power to the truck. The Wheel Cylinder is encased in a cast-iron or aluminum structure on the backing plate, which contains two pistons with cup seals, an expander spring, and dust boots. The brake fluid enters through a center bore, and when you press the pedal, it causes the pistons to move outwards, which pushes the shoes into the drum while the seals expand to prevent leaks. When there is a drop in pressure, the return springs pull the shoes back, and the expander spring holds the seals tight for the next stop. The GMC Sierra's earlier models came with heavier cast iron units that would rust. The later models went with a lighter version in a design known as an aluminum Wheel Cylinder that wouldn't rust. Both types have a bleeder screw for easy air removal. When moisture is absorbed by glycol fluid, it can cause blemishes in the bore, making the Wheel Cylinder leak or seize. This shows up as a low pedal or dragging brakes. For every GMC Sierra drum brake job, you want to pull back each boot. If fluid pours out or honing would leave over 0.003 inch clearance, replace or rebuild the Wheel Cylinder with fresh seals, boots, and spring.

Each OEM GMC Sierra Wheel 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.
