What is the replacement interval for brake discs?
2 Answers
The replacement interval for brake discs is approximately when the vehicle has traveled 80,000 to 100,000 kilometers. The steps for replacing brake discs are: 1. Lift the vehicle and remove the tires; 2. Remove the bolts of the brake caliper, open the brake caliper, and take out the old brake pads; 3. Push the brake piston back in, install the new brake pads; 4. Reinstall the brake caliper, tighten the caliper bolts to the specified torque, and reinstall the tires; 5. Press the brake pedal several times to eliminate the gap between the brake pads and the disc, allowing the brake piston to reset; 6. Check if the brake fluid pump is functioning properly. Conditions for replacing brake discs include: 1. The thickness of the brake disc is less than the minimum maintenance standard allowed by the vehicle manufacturer; 2. The wear indicators on the brake disc come into contact with the disc; 3. The brake disc exhibits abnormal wear or tapered wear.
The timing for replacing brake discs actually varies from person to person, but I've found that it mostly depends on your driving habits and the type of vehicle. For example, I drive an SUV and frequently navigate city traffic with constant braking due to congestion. As a result, my brake discs wore out severely after just 40,000 kilometers and had to be replaced. If you mostly drive on highways and use the brakes less, your brake discs might last over 70,000 kilometers. Brake disc thickness is crucial—have it measured every time you get your car serviced. If it falls below the manufacturer's recommended thickness or shows signs of scoring or vibration, it's time to replace them. Additionally, brake pads should be replaced first; after changing pads two or three times, it's usually time to replace the discs. Overall, don’t wait until the brakes feel soft or make noise to address the issue—that’s unsafe. I recommend checking them every 20,000 to 30,000 kilometers to save money and drive with peace of mind.
