GMC 19150002 Brake Shoe

Whenever brake shoes are replaced, it's essential to replace the return and hold-down springs as well, as the continuous heating/cooling cycle weakens the springs over time, leading to dragging shoes and accelerated wear. To begin the process, loosen the wheel lug nuts, raise the rear of the vehicle, and support it on jack stands securely. Block the front wheels to prevent rolling, and remove the rear wheels. Proceed to remove the brake drum/hub, ensuring the drums aren't stuck due to corrosion by using penetrating oil and gentle tapping. If the drum is locked onto the shoes due to excessive wear, release it by aligning the hole with the adjuster and backing it off. For brake shoe replacement, follow the specified procedures for removal and installation, including replacing drum retainers, disassembling components, and cleaning or lubricating parts as necessary. Check the brake drum for wear and resurface it if required or replace it if worn beyond the maximum allowable diameter. Address any brake fluid leakage at the wheel cylinders by replacing or overhauling them. Verify that the backing plate mounting bolts are tight and clean the shoe contact areas with emery cloth. Install the drum and adjust the brakes using an adjusting tool to ensure proper pedal position and functionality before driving.
