WARNING
• If at any point in this procedure the hydraulic system is opened, the brakes must be bled after
the correct reinstallation of the brake components. Failure to bleed the brakes could result in
decreased braking performance due to air being trapped in the hydraulic system. Use only
DOT 5 brake fluid. See Bleeding the Hydraulic Brake System on page 5-22.
• Prior to servicing hydraulic brakes, thoroughly clean the vehicle, paying particular attention
to areas immediately surrounding hydraulic connections, to prevent dirt or debris from
entering system.
