Determining brake disc wear:

• 1. Check the brake disc thickness

• 2. Weigh the brake disc

• 3. Check the wear indicators





Always replace the brake discs on both sides of the axle when:

• the brake discs must replaced because they are worn,

• the replacement brake disc has been technically modified, which can be determined by the revised part number.

If one of the three defined wear limit is reached, then the brake disc can no longer be used.

The brake disc must be replaced.

In this case, replace the brake discs on each side of the axle. Refer to => [ Front Ceramic Brake Disc, C/SIC Caliper ] Front Ceramic Brake Disc, C/SIC Caliper

Brake pads likewise must always be replaced on both sides of the axle. => [ Front Brake Pads, Ceramic Brakes ] Front Brake Pads, Ceramic Brakes
