How do I properly inspect, measure, and refinish brake discs?

To inspect the brakes, start by loosening the wheel lug nuts and raising the vehicle on jackstands. Remove the brake caliper, suspending it out of the way with wire. Visually inspect the disc surface for score marks and damage, checking both sides. If pulsating has been noticed during braking, suspect disc runout. To check runout, reinstall the lug nuts and use a dial indicator to measure the reading, ensuring it does not exceed the allowable limit. If necessary, refinish the disc. It is important to not machine the disc below the specified minimum thickness, which can be checked with a micrometer. For removal, remove the caliper mounting bracket and the lug nuts if they were reinstalled. Mark the disc for reinstallation and remove the retaining screw. During installation, wire-brush the backside of the disc and clean the hub face. Apply high-temperature anti-seize and align the index marks before tightening the retaining screw. Install the caliper mounting bracket and caliper, tightening the bolts to the proper torque. Lower the vehicle, tighten the lug nuts, and depress the brake pedal to bring the pads into contact with the disc. Bleeding is only necessary if the brake hose was disconnected. Finally, carefully check the brake operation before driving the vehicle.

GMC Acadia Brake Disc

The Brake Disc, or rotor, in the GMC Acadia automobiles is imperative to the disc brake mechanism as it emits the friction necessary for brake provisions. These discs are generally made of gray iron and such castings may have cooling enhancements such as fins or vanes. In the past some alterations such as drilled or slotted discs have been employed to increase the quantity of heat that is dissipated as well as reduce noise but the outcome is shorter pad life. Another important component of maintenance of the GMC Acadia is the Brake Disc, as the warping, cracking or rust may affect the car braking ability. These issues can be controlled by conducting frequent checks on the brake pads and replacing them when they wear out, this way the brake system will be well functioning.
