How to inspect and replace brake discs on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?

To inspect and replace brake discs, first loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the brake caliper and visually check the disc surface for damage. Deep score marks or cracks may require disc refinishing or replacement. To check disc runout, place a dial indicator at a point about 1/2-inch from the outer edge of the disc. It's critical that the disc not be machined to a thickness under the specified minimum thickness, which can be checked with a micrometer. To remove the disc, remove the caliper mounting bracket bolts and slide the disc off the hub. To install the new disc, place it in position over the threaded studs, install the mounting bracket and brake pads, and then install the caliper onto the mounting bracket. Finally, install the wheel and lug nuts, lower the vehicle, and depress the brake pedal a few times to bring the brake pads into contact with the disc.

GMC Sierra Brake Disc

The Brake Disc is an integral assembly of the disc brake system in GMC Sierra, used for application of friction that results in decrease of vehicle speed and eventual halt. The brake pedal operates through a hydraulic mechanism in a master cylinder and engaging this pedal squishes its push rod, through hydraulic fluid which in turn pushes caliper's pistons making the brake pads engage the rotor to enable this crucial stopping function. The rotors are usually made from grey iron but some recent models of the Brake Discs may be made from carbon fiber or ceramic composite. For many years now several types of brake rotor have been used in GMC Sierra vehicles, namely the drilled, the slotted and the two piece rotor types. Drilled and slotted rotors enhance heat removal and also lessen noise, but there are chances of pad wear. Floating rotors help to balance the distribution of the material for lighter construction, better heat dissipation and performance under conditions of increased load. It is also wise to overcome other problems like warping or cracking of the disc or rusting to ensure efficient use of the brake.

Each OEM GMC Sierra Brake Disc 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 inspect and replace brake discs on Chevrolet Avalanche,Silverado,Suburban,Tahoe,GMC Sierra,Yukon,Yukon Denali and Yukon XL?
A: To inspect and replace brake discs, first loosen the wheel lug nuts, raise the vehicle, and support it securely on jackstands. Remove the brake caliper and visually check the disc surface for damage. Deep score marks or cracks may require disc refinishing or replacement. To check disc runout, place a dial indicator at a point about 1/2-inch from the outer edge of the disc. It's critical that the disc not be machined to a thickness under the specified minimum thickness, which can be checked with a micrometer. To remove the disc, remove the caliper mounting bracket bolts and slide the disc off the hub. To install the new disc, place it in position over the threaded studs, install the mounting bracket and Brake Pads, and then install the caliper onto the mounting bracket. Finally, install the wheel and lug nuts, lower the vehicle, and depress the brake pedal a few times to bring the brake pads into contact with the disc.
