Periodically remove the brake drums and clean the brake
parts of dirt. Periodicity of this operation depends on service
conditions of the automobile. In the summer season and when
driving on mud-covered roads, carry out cleaning more fre-
quently.
Keep a close watch on the brake system serviceability, timely
perform its adjustment and eliminate detected faults.
For restoring the normal clearances between the brake shoes
and drums and for reducing the brake pedal travel, adjust the
brake drum-to-shoe in the following sequence:
1. Jack up the wheel which brake is to be adjusted.
2. Check the adjustment of the wheel hub bearings for
correctness and carry out the adjustment, if required, as
indicated in the section "Wheel Hubs".
3. Rotate the wheel and gradually turn the adjusting eccen-
tric 19 (Fig. 61) or 4 (Fig. 62) until the wheel is braked.
4. While rotating the wheel, gradually back out the eccentric
until the wheel starts rotating freely, without brushing of the
drum against the brake shoes.
5. Similary, adjust the drum-to-shoe clearances in the
remaining brakes.
When adjusting the brakes of the front wheels and the front
shoes of the rear wheel brakes, rotate the wheel forward. When
adjusting the rear shoes of the rear wheel brakes, rotate the wheel
backward.
For reducing the clearance, turn the eccentric in the
direction of the wheel rotation and for increasing the clearance,
rotate the eccentric in the reverse direction.
6. Make a road test to check the brakes for drum heating and
for uniform application.
During the brake running adjustment, do not touch the
anchor pins as the Manufacturer's setting of the brake shoes will
be disturbed.
If the rivets of the linings are flush-mounted on a depth of
less than 0.5 mm, replace the shoes or linings.
For adjusting the brake pedal free travel, change the length of
the vertical rod 9 (Fig. 60). The brake pedal full travel is 200 mm.
The brake pedal full travel must be 5-14 mm.
Check the brake pedal free travel when the engine is shut
down.
