Do Front and Rear Brake Pads Need to Be Replaced Together?
1 Answers
Front and rear brake pads do not need to be replaced together. Here are the specific reasons: 1. Differences between front and rear brake pads: Compared to front brake pads, rear brake pads have a longer service life. Under normal driving conditions, front brake pads typically need replacement every 30,000 to 50,000 kilometers, while rear brake pads can last between 60,000 to 100,000 kilometers before replacement. There is no fixed time for replacing brake pads, as their replacement cycle depends not only on their lifespan but also on the vehicle's driving conditions and individual driving habits. New brake pads are approximately 1.5 cm thick. When replacing brake pads, both pads on the same axle should be replaced together to ensure balanced braking performance on both sides. 2. Differences in brake pad materials: Brake pads vary in material, brand, and vehicle application. Common materials used in brake pads include asbestos, high-carbon fiber, semi-metallic, and ceramic. Asbestos brake pads have been phased out, with semi-metallic and ceramic being the most common today. Semi-metallic pads are more affordable and widely used in household vehicles, while ceramic pads offer superior performance, including better wear resistance, high-temperature tolerance, thermal stability, faster heat dissipation, and higher friction coefficients, making them more suitable for mid-to-high-end vehicle models.
