How Often Should BMW Brake Pads Be Replaced?
1 Answers
BMW 5 Series brake pads generally need to be replaced every 80,000 kilometers. Automotive brake pads are typically composed of a steel plate, an adhesive heat insulation layer, and a friction block. The steel plate is coated to prevent rust, and the coating process is monitored using an SMT-4 furnace temperature tracker to ensure the temperature distribution during coating meets quality standards. When purchasing brake pads, pay attention to the "Four Checks and Two Selections": 1. Four Checks: (1) First, check the friction coefficient. The friction coefficient determines the basic braking torque of the brake pads. If it's too high, it can cause wheel lock-up, loss of control, and pad burning during braking. If it's too low, the braking distance will be excessively long. (2) Second, check safety. Brake pads generate instantaneous high temperatures during braking, especially during high-speed driving or emergency braking. Under high temperatures, the friction coefficient of the pads may decrease. (3) Third, check comfort. This includes braking feel, noise, dust, smoke, and odors, which directly reflect the friction performance. (4) Fourth, check lifespan. Typically, brake pads should last for about 30,000 kilometers. 2. Two Selections: (1) First, choose brake pads produced by reputable manufacturers, which should have a license number, specified friction coefficient, and compliance with execution standards. The packaging should include a certificate of compliance, production batch number, and production date. (2) Second, opt for professional installation at a certified repair shop.
