Question

Quizplus · Accepted Answer

Both technicians are correct. Disc brake pads should indeed be replaced when they are worn down to the thickness of the steel backing to prevent damage to the brake rotor and ensure proper braking performance. Additionally, removing and inspecting the pads whenever there is a brake performance complaint is a standard diagnostic procedure to identify issues such as uneven wear, contamination, or damage to the brake pads.
