Fit the shoe hold down springs (6), cup washer (5)
and pins (4) to both the shoes. Remove the elastic
band from around the wheel cylinder and reduce
the length of the adjuster assy. until the shoes rest
on the wheel cylinder pistons.
Fit the hand brake cable to the lever on the trailing
shoe, ensuring the cable is correctly located in the
end of the lever.
Note:
The cable should just be tight without
pulling the hand brake lever from the 'fully off'
position.
Ensure that the shoe linings (2/3) are free from oil
and grease.
During servicing of shoes/replacement, the brake
dia. overshoes should be set to 294 to 294.5 mm
by adjusting the ratchet.
This is to have minimum clearance between
shoes and drum.
Clean the exterior of the drum with a wire brush
and wipe the inside with a clean rag.
Note :
If the drum looks poor in condition, or is
scored inside where the brake shoes contact, fit a
new drum.
Offer the drum to the brake and adjust the length
of the adjuster until it is only just possible to fit the
drum over the brake shoes. Check the pawl is in
contact with the adjuster nut on the adjuster and
fit the drum. Repeat procedure with the opposite
rear brake and operate the foot brake through its
full stroke 10 to 20 times. Check the movement of
the hand brake and road test the vehicle.
