Car brake skimming is a process used to restore the smooth surface of the brake rotors, which are critical components of the brake system. Over time, rotors can develop uneven wear, grooves, or warping due to heat and friction from braking. Skimming involves removing a small layer from the rotor’s surface using a lathe, creating a flat and even surface area for the brake pads to contact. This procedure can improve braking performance, reduce vibrations, and extend the life of the brake rotors. However, it’s a temporary fix compared to replacing the rotors and is usually considered when the rotors are not too worn down to be machined safely. Proper assessment by a professional is essential to determine if skimming is suitable for a given situation.
