How to Self-Check Brake Pads?
2 Answers
The methods for self-checking brake pads are as follows: Check the thickness: A new brake pad is generally about 1.5cm thick. With continuous friction during use, the thickness gradually wears down. When visual inspection shows that the brake pad thickness is only about 1/3 of the original (approximately 0.5cm), the owner should increase the frequency of self-checks and be prepared to replace them at any time. Feel the braking force: When the brake pads become thin, the braking effect of the car will be affected. At this time, you need to press the brake pedal deeper to achieve the same braking effect that was previously achieved with a light press. The braking effect in the first half of the pedal stroke is significantly weakened.
I find checking brake pads is actually quite simple, mainly through visual inspection. If you turn the steering wheel to one side, you can see the thickness of the brake pads through the gaps in the wheel hub. A brand-new pad is typically about 10 to 12 millimeters thick, and it should be replaced when worn down to around 3 millimeters. I use a flashlight to carefully observe the contact surface between the metal plate and the brake disc. If I notice the metal block is almost gone, it's time for an immediate replacement. If you hear a sharp squealing noise when braking, that's often the brake pad wear indicator reminding you. Don’t forget that some high-end cars have sensors—if the warning light comes on, don’t delay. DIY can save money, but safety comes first. If the thickness is unclear or you're unfamiliar with the process, it’s more reliable to have them replaced at a repair shop. I usually check every 5,000 kilometers to avoid costly repairs later.
