WARNING
Disc brake components rarely require dis-
assembly. Therefore, always follow these
preventive measures:
• Never disassemble brake components
unless absolutely necessary.
• If any connection on the hydraulic brake
system is disconnected, the entire brake
system must be disassembled, drained,
cleaned, properly filled, and bled after
reassembly.
• Never use solvents on internal brake
components.
• Use only clean or new brake fluid for
cleaning brake components.
• Brake fluid may damage painted surfaces
and plastic parts. Therefore, always clean
up any spilt brake fluid immediately.
• Avoid brake fluid coming into contact
with the eyes as it can cause serious
injury.
• FIRST AID FOR BRAKE FLUID ENTERING
THE EYES:
• Flush with water for 15 minutes and get
immediate medical attention.
