When replacing brake discs, always follow the manufacturer’s instructions and recommendations. The following tips are provided for information purposes only and are not and should not be considered as installation instructions.
- Brake discs should always be replaced in pairs on the same axle and always fitted with new brake pads.
- Before replacing the brake discs on your vehicle, inspect the steering system and suspension system of the vehicle if there are broken elements, they should be repaired or replaced with ones free from defects. If both systems are in good working order, you can start replacing the discs.
Picture 1 shows old brake pads and old brake discs installed on a vehicle.
Unscrew the caliper housing and remove the brake pads.
Dismantle the brake carrier and the old discs (picture 3). As you can see in this picture, the hub is covered with rust or dirt. Clean all the parts thoroughly (pictures 4 and 5).
After cleaning the hub, measure side hub runout using a dial indicator (picture 6).
Remove the new brake discs from the box (picture 7). Clean the surface of each disc to remove the grease (picture 8).
Now attach a new brake disc onto the hub (picture 9). Check side hub runout to make sure it is not higher than the value specified by the manufacturer (usually 0.08 mm).
After installing the new discs, it is time to install new brake pads (picture 10).
- When the brake pads are installed, put on the wheel and screw it in place.
During the initial period of using the new brakes (approx. 200-300 km), you are advised to apply the brakes gently.
