CAUTION:
WARNING
EAS00579
Disc brake components rarely require dis-
assembly.
Therefore, always follow these preventive
measures:

Never disassemble brake components un-
less 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 reas-
sembly.

Never use solvents on internal brake com-
ponents.

Use only clean or new brake fluid for clean-
ing 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 im-
mediate medical attention.
