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 eccentric
19 (Fig. 70) or 4 (Fig. 71) until the wheel is braked (Fig. 71).
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 te drum-to-shoe clearances in the remain-
ing 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.
Adjust the brake pedal free trave l by setting the stop of the
stop-light switch 14 (Fig. 67) in a position ensuring the free travel
of brake pedal in a range of 5 - 14 mm. Check the brake pedal
free travel when the engine is shut down.
Fill the brake hydraulic system in the following sequence:
1. Check all the connections of the brake hydraulic system
for leaks and the flexible hoses for proper condition.
2. Clean of dust the brake master cylinder reservoir surface
round the cap and unscrew the cap. Fill up the reservoir with
brake fluid.
3. Remove the cap from the by-pass valve of the brake master
cylinder or from the pressure regulator and put the end of a
rubber hose, about 400 mm long on the by-pass valve.
Dip the other end of the hose in a glass vessel of at least 0.5-
l capacity half filled with brake fluid (Fig. 72).
