The braking system is one of the most important safety features of a car. Brake pads, brake discs, calipers, and brake fluid all work together to perform the braking function. Regularly checking the wear thickness of the brake pads is crucial for routine maintenance. If the wear exceeds 4-5 millimeters, replacement should be considered to ensure proper braking performance. If you experience sharp noises, vibrations, or a soft pedal feel when braking, you should have your brakes inspected by a professional as soon as possible.
