How to Determine the Thickness of Brake Pads?
2 Answers
To determine the thickness of brake pads, you can follow these methods: 1. Check the thickness visually. New brake pads are generally about 37.5px thick. If you observe that the thickness of the brake pads has reduced to about one-third of the original, you need to monitor the thickness changes frequently. 2. Listen for sounds. If you hear a sharp, screeching noise, it indicates that the thickness of the brake pads has worn below the limit marks on both sides. Brake pads, also known as brake linings, are friction materials fixed on the brake drums or discs that rotate with the wheels. The friction linings and blocks bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration.
I've been driving for over a decade, and judging brake pad thickness is quite simple. Usually, I can directly see the brake pads through the wheel gaps. New pads are about 10-12mm thick, and they should be replaced when worn down to below 3mm. Pay attention to the sound when braking – if you hear a sharp metallic scraping noise, or if the brakes feel soft and the stopping distance becomes longer than before, it means the pads are worn thin. Every six months, I use my phone's flashlight to check the pads through the wheel hub – it's quick and safe. Remember, the braking system is crucial. Worn pads can not only damage the brake discs, leading to higher costs, but also increase the risk of accidents. I don't do much DIY, but I recommend going to a professional shop for regular maintenance, as they can measure the thickness accurately.
