How often should the front brake pads of a BMW X3 be replaced?
2 Answers
BMW X3 front brake pads should be replaced every 30,000 kilometers. Brake Pads: Brake pads, also known as automotive brake linings, are the most critical safety components in a car's braking system. Automotive brake pads are generally 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 SMT4 furnace temperature tracker to ensure the temperature distribution during coating meets quality standards. Method for replacing brake pads on a BMW X3: Release the brake button, remove the tire, detach the brake caliper, and then remove the rear brake caliper. Use an E40 Torx tool to remove the electronic brake motor (2 screws). Then, rotate the caliper on the electronic brake shaft clockwise with an E30 Torx tool until it is tight! Next, use a specialized brake tool to press the brake caliper back, install the new brake pads, reattach the electronic brake motor to the caliper, and proceed with normal installation! After installation, press the electronic brake button several times, and if necessary, take the car for a test drive to reset the system.
I've been driving my BMW X3 for almost three years now, mostly commuting in the city, so the front brake pads require frequent inspection. The last time I replaced them was at around 60,000 kilometers when the brakes started squeaking slightly. A measurement at the shop showed they were down to just 2mm thickness. City driving with constant stop-and-go traffic and numerous traffic lights means frequent braking, which accelerates wear. Compared to highway driving, urban conditions may necessitate replacement 10,000 to 20,000 kilometers earlier. BMW's built-in wear sensors are quite convenient - they trigger a warning when thickness reaches 3mm to 1mm, reminding you not to delay. I recommend having technicians check pad wear during routine maintenance every 2-3 years or 40,000-60,000 kilometers. This preventive approach avoids roadside emergencies and saves money by allowing timely OEM replacements. While you can lightly press the brakes at home to listen for unusual sounds, don't rely solely on this method - professional measurement remains the most reliable approach.
