INTRODUCTION

WARNING

EWA14101

Disc brake components rarely require disas-
sembly. Therefore, always follow these pre-
ventive 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.
