Loosen the lock nut (8) on the master

wards the master cylinder as far as it will
go on the threads of the push rod.
Screw the push rod (9) completely into the
clevis, then unscrew it three to four turns.
Adjust the brake adjuster bolt (7) until the
brake pedal (10) is positioned as you like it.
Screw down and tighten the lock nut (6)
on the brake adjuster bolt (7).
Screw the master cylinder push rod (9)
out of the clevis until it just contacts the
master cylinder piston.
Then, screw the push rod into the clevis
to obtain a minimum clearance of 0.02 –
0.04 in (0.5 – 1 mm) between the master
cylinder push rod and the master cylin-
der piston.
Lock the push rod in position with the
lock nut (8).
 
CAUTION
Be sure there is the specified clearance
between the master cylinder push rod
and the master cylinder piston. If this
caution is not observed, the brake will
remain slightly applied, with subse-
quent brake overheating and wear of
pads and discs.
Clearance between the push rod and
 
the piston 0.02 – 0.04 in (0.5 – 1 mm).
WARNING
After making any brake adjustment ap-
ply the brakes repeatedly. Try the
brakes in a parking lot or other area
where there is little traffic. After you
have completed the adjustment, lift the
wheel free of the ground and ensure
that it rotates freely when the brake is
released.
