CAUTION / NOTICE / HINT

NOTICE:

  • Immediately after installing the brake pads, the braking performance may be reduced. Always perform a road test in a safe place while paying attention to the surroundings.
  • After replacing the rear disc brake pads, the brake pedal may feel soft due to clearance between the rear disc brake pads and rear disc. Depress the brake pedal several times until the brake pedal feels firm.
  • After replacing the rear disc brake pads, always perform a road test to check the braking performance and check for vibrations.
  • Make sure that brake cleaner containing mineral oil does not contact the rubber seal. If brake cleaner containing mineral oil contacts the rubber seal, immediately wash it with water and wipe it clean.
