Brake lining

Sintered metal lining generally handles heating and wear well in wet conditions. Compared to organic, it may be louder and cause more disc wear. Use a disc that permits metallic pads.

When to replace and how to start

• Inspect the pads in case of poor braking, uneven wear, or contamination. Replace both pads in the same caliper; check the minimum permitted thickness in the brake manual.
• Remove the safety pin and the old pair. Prepare space for the new pads according to the procedure for your specific caliper, then insert the spring, the new pair, and the safety pin. Do not grease the friction surfaces.
• Check for free wheel rotation and brake lever operation. Bed in the new pads by performing several gradual slowdowns in a safe area, without locking the wheel.
