Study brake discs before damage occurs.
A commonly used four-point braking operation on dilatory pattern passenger vehicles unreal in the USA is the disc brake. Maintaining disc brakes is easier than drum brakes, because the parts are visible without much effort. Your regular maintenance procedure should include a process to inspect brake discs so that repairs can be made to worn discs before your ability to stop your vehicle is compromised.
Instructions
1. Park the vehicle on a spot that is level and has a hard surface. Loosen, but do not remove, the lug nuts on the wheel you will be inspecting. Lift the vehicle with a floor jack and place a jack stand under the frame to support it while you inspect the brake disc behind each wheel. Lower the vehicle onto the jack stand and remove the floor jack.
2. Remove the wheel's lug nuts and pull the wheel off the end of the axle, exposing the brake rotor and caliper. Place the wheel off to the side and place the lug nuts together near the wheel.
3. Wipe the exposed brake assembly with a rag to remove brake dust and debris that may be covering damage to the brake disc. Turn the rotor by hand so that you can visually inspect the surface of the brake disc. Putting a front-wheel drive in neutral will allow you to turn the rotor by hand. Look for grooving in the surface of the disc caused by worn brake pads. Another sign of wear is the disc itself may be worn thin, creating a hole in its flat surface. If any damage is seen, continue on to the next step. Pull the brake disc off the axle. Inspect it visually for wear, grooving, cracks and warps. These will dramatically affect the way each brake works.
Disconnect the disc brake caliper from the brake disc using an Allen wrench to remove the mounting bolts on the back of each caliper. Two or three long bolts hold the caliper in place, and once removed, the caliper slides off the edge of the brake disc. Keep the caliper positioned so that you do not stretch the brake line attached to it when you inspect brake discs with the caliper removed.
5. If not, clean the brake assembly and brake disc, and replace the wheel. Continue inspecting the other brake disc on the vehicle.4. Measuring the width of the brake disc at its edge is another way to determine whether the brake disc can be machined flat and reused.
