MAJOR OVERHAUL
It is essential that the shoe linings are inspected
at regular intervals to prevent the drums being
permanently damaged and subsequently making
drum removal extremely difficult.
1. Choke the front wheels, release the hand
brake and jack up the rear wheels. Support
the rear axle with horse stands.
2. Slacken off the hand brake cable.
3. Remove the wheel.
4. Now take out the drum. If the drum is not
coming out easily, use the M8x1.25 bolts, 2 nos.
Screw the bolts in the tapped holes provided on
the drum’s wheel mounting face. First fit the both
bolts in the drum till it reaches to hub face (8mm
approx.). Then screw the both bolts
simultaneously, so that drum will come out slowly.
Do it till drum fully came out from brake.
5. After removing the drum & servicing the brake,
the hand brake lever stopper to be reset on the
trailing shoe web and the hand brake cable to be
adjusted.
