Brake Pad Lifespan?
2 Answers
Under normal driving conditions, the service life of front brake pads is approximately 30,000-50,000 kilometers, while rear brake pads last about 60,000-100,000 kilometers. Once severe wear is detected, immediate replacement is necessary. Below are relevant details about brake pads: 1. Introduction: Brake pads, also known as brake linings, are the most critical safety components in a vehicle's braking system. They play a decisive role in braking performance, making quality brake pads the guardian angels for both drivers and vehicles. 2. Composition: Brake pads typically consist of steel plates, adhesive heat insulation layers, and friction blocks. The steel plates undergo anti-rust coating processes, with temperature distribution during coating monitored by SMT-4 furnace temperature trackers to ensure quality. The heat insulation layer is made of non-conductive materials for thermal isolation. Friction blocks comprise friction materials and adhesives, which create friction when pressed against brake discs or drums to decelerate the vehicle. Due to friction, these blocks gradually wear out, with generally cheaper brake pads wearing faster.
The lifespan of brake pads is actually related to my driving habits. As a commuter in the city, I need to replace them every 30,000 to 50,000 kilometers on average because frequent braking in congested intersections causes much faster wear. Last time, I delayed the replacement, and the braking distance became longer, almost causing an accident. Now, I check the thickness every 20,000 kilometers and replace them if it's below 2mm to avoid safety risks. Weather also has an impact, such as high temperatures in summer which can accelerate the aging of brake pad materials. I recommend choosing better-branded products; although they are more expensive, they are more durable and cost-effective in the long run. Safety is the most important—don’t wait for problems to arise before taking action. Driving smoothly can also help extend their lifespan.
