What are the criteria for replacing brake pads?
2 Answers
Brake pad replacement criteria are primarily determined by the thickness of the brake pads and the wear condition of the brake discs, typically between 40,000 to 60,000 kilometers. Here is some extended information on brake pad maintenance: 1. Avoid sudden braking: Emergency braking causes significant damage to brake pads. When driving normally, pay attention to braking gradually or using intermittent braking, which results in less wear on the brake pads. 2. Reduce braking frequency: Develop a good habit of minimizing braking while driving. Use engine braking to reduce speed before applying the brakes for further deceleration or stopping. Downshifting can also help achieve speed reduction. 3. Break-in period after replacing brake pads: After installing new brake pads, be sure to pump the brakes several times to eliminate the gap between the pads and the brake discs. Additionally, new brake pads require a break-in period of 200 kilometers to achieve optimal braking performance, so drive cautiously immediately after replacement.
Having driven for over a decade, I can't stress enough how crucial brake pad replacement is. Always listen for sounds while driving – if you hear metallic squeaking when braking, it's definitely a sign of severely worn brake pads. I recommend checking behind the wheels monthly; new brake pads are about 1.2cm thick and should be replaced when worn down to 3mm. If you notice significantly longer braking distances or a spongy pedal feel, your brake pads are already overloaded. Lifespans vary by vehicle type – city-driven cars often need replacement at 40,000km, while highway vehicles may last 60,000km. Don't forget to inspect the brake discs too – deep grooves mean they need attention. Developing regular inspection habits is the safest approach, as brake failure during emergencies can be extremely dangerous.
