A contaminated brake disc or pad reduces stopping power. Discard contaminated pads and clean a contaminated disc with a high
quality brake degreasing agent.
Use only DOT 4 brake fluid.
The brake caliper and brake pads can be removed without disconnecting the hydraulic system.
Once the hydraulic system has been disassembled, or
if
the brakes feel spongy, the system must be bled.
Do not allow foreign material to enter the system when filling the reservoir.
Brake fluid will damage painted, plastic, and rubber parts. Whenever handling brake fluid, protect the painted, plastic and rubber
parts by covering them with a shop towel. If fluid does get on these parts, wipe it off immediately with a clean cloth.
Always check brake operation before riding the motorcycle.
Inhaled asbestos fibers have been found to cause respiratory disease and cancer. Never use an air hose or dry brush to clean brake
assemblies. Use an OSHA-approved vacuum cleaner or alternate method approved by OSHA, designed to minimize the hazard
caused by airborne asbestos fibers.
