1. If the friction surface of the brake disc is not accessible, remove the caliper together with the brake pads

2. Clean the friction surfaces of the brake disc with denatured alcohol or an approved brake cleaner.

3. Inspect the friction surfaces of the brake disc. Look for traces of:

• severe rusting and/or pitting;
• cracks and/or burns (tarnished flowers);
