How to Check Brake Pad Thickness?
3 Answers
Methods to check brake pad thickness: The thickness of brake pads can be visually inspected. In some cases, the brake pads can be seen through the gaps in the wheel hub. If the brake pads have worn down to one-third of the standard thickness, replacement is recommended. However, due to the wheel hub design of some car models, it is difficult to check the brake pad thickness without removing the tires, which can be quite troublesome. The standard thickness of brake pads is around 1.5 cm, and it decreases due to friction during braking operations while driving. The critical thickness for brake pads is generally around 2-3 millimeters. If the brake pad thickness is less than 3 millimeters, it must be replaced.
I've always considered regular inspection of brake pad thickness as a crucial part of my car maintenance. I've been doing it myself for several years, and the method is actually quite simple: first remove the wheel, loosen the screws, and then you can see the brake pads inside the caliper. The normal thickness should be above 5mm - if it's too thin, problems may occur, such as hearing a sharp metallic sound when braking. I usually feel the thickness with my finger or measure it with a simple ruler. If it's below 3mm, it's time to replace them. Remember to check them every time you change the oil, roughly every 10,000 kilometers or so. Safety is the top priority, and neglecting this could lead to longer braking distances and potential accidents. After making this a habit, my car has had fewer issues, saving me a lot on repair costs, and I feel much more at ease on the road.
I drive primarily for my family's safety, so I pay special attention to the condition of the brake pads. A simple way to check the thickness is to look through the wheel's opening gap. When the brake pads are too thin, it's time to replace them. If the thickness is less than one or two millimeters, the braking performance will significantly decline, making it easier to skid in emergencies. I recommend checking at least every six months, or immediately if you feel any hesitation when braking. Beginners can use this method to learn the basics, and don't hesitate to ask a friend at the auto repair shop if unsure. This isn't just about saving money—it's about the safety of your family's travels. Don't wait until an accident happens to regret it. Developing a habit of regular maintenance can prevent more trouble.
