Brake pad composition

The friction material presses against the disc, and the backing plate keeps it in the correct position in the caliper. Replace both pads together if they are worn, damaged, or contaminated with oil. During installation, also check the safety pin and wheel free rotation.

When to replace and how to start

• Inspect the pads if you notice poor braking, uneven wear, or contamination. Always replace both pads in the same caliper; check the minimum allowed thickness in your brake manual.
• Remove the safety pin and the old pair. Follow the procedure for your specific caliper to create space for the new pads, then insert the spring, the new pair, and the safety pin. Do not grease the friction surfaces.
• Check wheel clearance and lever operation. Break in the new pads with several gradual decelerations in a safe area without locking the wheel.
