When the bleeding operation is complete, the
master cylinder must be refilled.
Check the fluid in the master cylinder every
1,000 miles.
BRAKE PEDAL
REMOVAL
1. Remove the nut and shakeproof washer holding
the pedal rod to the brake pedal lever assembly.
2. Remove pedal rod using Pedal Puller Tool
J-2795 and washer.
3. Remove the push rod clevis pin (28), Figure 1,
disconnect the brake pedal pull back spring
(21) and remove the master cylinder push rod
(27).
4. Remove the brake pedal retaining snap ring
from the pedal shaft, and remove the brake
pedal.
Check brake pedal bushings and replace if
excessively worn.
To reassemble the brake pedal, reverse the steps
outlined above.
ADJUSTMENTS
BRAKE PEDAL ADJUSTMENT
The brake pedal lever (29), Figure 1, should
have between 1/4" to 3/8" free play. (Measure at
lower end of pedal lever (29.) The free play is the
movement of the pedal lever before the master
cylinder push rod (27) contacts the master cylin-
der piston.
This adjustment is important to assure that the
master cylinder piston returns to its normal posi-
tion, otherwise the brakes will drag.
To adjust, loosen the push rod lock nut and
increase or decrease the length of the push rod
(27) until this free play of 1/4" to 3/8" is obtained.
After correct adjustment has been obtained,
tighten the push rod lock nut, lubricate the pedal
linkage and recheck free play.
HAND BRAKE LEVER ADJUSTMENT
The hand or parking brake applies the rear wheel
brakes by brake cables connected to the hand brake
lever and the rear brake shoe cable levers.
To adjust the parking or hand brake, pull the
hand brake lever one notch outward from the fully
released position.
1. Loosen the clevis lock nut, Figure 1.
2. Remove clevis pin (22) and shorten the brake
cable (7) until a slight drag is felt at each rear
wheel.
3. Tighten the lock nut and install cotter pin to
secure clevis pin (22).
Release the hand brake lever fully and recheck
rotation of the rear wheels. They should turn
without any brake drag.
MINOR BRAKE ADJUSTMENT
NOTE: Brake drums should be at approxi-
mately room temperature when making brake
shoe adjustments. If brakes are adjusted when
the drums are hot and expanded, the shoes may
drag when the drums cool and contract.
The floating shoe type brake assembly has
shoes that center them selves in the drums when
the brakes are applied. Therefore, the brake linings
wear uniformly and no major brake adjustments
are required.
1. Jack up all wheels, clear of the floor.
2. Check and remove end play in wheel bearings if
required.
3. Check to see that the parking brake lever is fully
released and the cable is not tight causing the
brakes to drag slightly.
4. Loosen the eccentric lock nut ( A), Figure 6, on
the rear of the backing plate.
5. Rotate wheel in forward direction and turn ec-
centric (B) downward until there is a heavy drag
indicating complete lining contact with drum.
