 SERVICE INFORMATION
 GENERAL INSTRUCTIONS
 · During servicing, keep oil or grease off the brake drum and brake linings.
 · Drain the brake fluid from the hydraulic brake system before disassembly.
 · Contaminated brake disk or brake pads reduce stopping power. Clean the contaminated brake
   disk with high-performance brake degreaser and replace the brake pads.
 · Do not use brake fluid for cleaning.
 · Bleed air from the brake system if the brake system is removed or the brake is soft.
 · Do not allow any foreign matters entering the brake reservoir when filling the brake reservoir
   with brake fluid.
 · Brake fluid will damage painted, coated surfaces and plastic parts. When working with brake
   fluid, use shop towels to cover and protect painted, rubber and plastic parts. Wipe off any splash
   of brake fluid with a clean towel. Do not wipe the motorcycle with a towel contaminated by
   brake fluid.
 · Make sure to use recommended brake fluid. Use of other unspecified brake fluids may cause
   brake failure.
 · Inspect the brake operation before riding.
