When should brake discs be replaced?
The service life of the front brake discs is on average 50,000–70,000 km, and 70,000–100,000 km for the rear ones. However, sometimes they will need to be changed earlier. New discs need to be installed if they wear down to the minimum thickness specified in the vehicle’s service manual. It is recommended to measure this with a vernier caliper once every 10,000 km. In addition, cracks and chips, uneven wear and warping indicate that the components need to be replaced.
Do I need to replace brake discs and pads together?
When replacing brake discs, it is recommended to install new pads at the same time. The old ones will have developed a wear pattern that corresponds to the old discs. Therefore, using these pads again risks premature wear of the discs and a decrease in braking performance.
Can I only replace one brake disc?
No, you cannot. Brake discs should only be replaced in pairs on an axle. Otherwise, due to a smaller thickness of the old part and, therefore, different lengths of the piston stroke, the brake mechanisms will fail to act simultaneously, which will lead to instability of the vehicle when braking.
