Bleed one side of system (two caliper
halves) at a time. Keep master cylinder
full during bleeding.
Attach a short hose and container to bleeder
valves (1) (one valve at a time).
Remove master cylinder cap (2). Fill cylinder
with FRH hydraulic fluid (see your -10).
Open bleeder valves (1).
Move handle (3) until fluid coming out of
bleeder valves (1) is free of air.
Hold handle (3) back in applied position (as
shown) and close bleeder valves (1).
After bleeding, add FRH hydraulic fluid only
as needed. Fluid level should be within
1/2-3/4-in (13-19mm) from top of cylinder.
Do not overfill (see your LO).
Pull control handle to applied position and hold
it there. If handle continues to move after ap-
plied position is reached, master cylinder, hose,
tube, or connection is bad. Repair or replace bad
parts (page 23-66).
