Frequent inhalation of brake pad dust, regardless of material composition, could be hazardous to your health.
  • Avoid breathing dust particles.
  • Never use an air hose or brush to clean brake assemblies. Use an appropriate vacuum cleaner.

NOTE: Make sure that the caliper pins are installed correctly. Upper caliper pin A and lower caliper pin B are different. If these caliper pins are installed in the wrong location, it will cause vibration, uneven or rapid pad wear, and possibly uneven tyre wear.
  • Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off immediately with water.
  • To prevent dripping brake fluid, cover disconnected hose joints with rags or shop towels.
  • Clean all parts in brake fluid and air dry; blow out all passages with compressed air.
  • Before reassembling, check that all parts are free of dirt and other foreign particles.
  • Replace parts with new ones as specified in the illustration.
  • Make sure no dirt or other foreign matter gets in the brake fluid.
  • Make sure no grease or oil gets on the brake discs, the brake disc/drums, or the pads.
  • When reusing brake pads, always reinstall them in their original positions to prevent loss of braking efficiency.
  • Do not reuse drained brake fluid. Use only clean genuine Honda DOT 3 or DOT 4 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.
  • Coat the piston, the piston seal groove, and the caliper bore with clean brake fluid.
  • Replace all rubber parts with new ones whenever disassembled.
  • Use recommended greases in the rear caliper set.
  • After installing the caliper, check the brake hose and line for leaks, interference, and twisting.
  • When you apply the silicone grease, make sure not to adhere to the terminal part of connectors and surrounding switches. Also do not touch the switches and the terminal part of connector by hands or glove that adheres the silicone grease.
