Adjusting the Free Travel of Brake Pedal
Every 20.000 Km (and also after the first 2,000-3,000 Km if the car is new), check and
adjust, if necessary, the brake pedal free travel. With the brake system serviceable and the
shoe-to-drum clearances of the rear wheels normal, the brake pedal free travel, with the engine
shut down, should be 3-5 mm. Adjust free travel by shifting stop- light switch 4 (Fig. 63)
together with buffer 6 after unscrewing nut 5. Adjustment over, tighten nut 5.
Brake Vacuum Booster
Every 30.000 Km check the vacuum booster for serviceability in the following manner:
depress the brake pedal 5-6 times, with the engine shut down, and holding the brake pedal
pressed, start the engine. With the vacuum booster serviceable, the brake pedal should move
further down upon starting the engine. If the pedal does not move further down, check for
tightness the hose connections to the intake manifold and to the vacuum booster, as loose
connections cause in leakage of air and sharply reduce vacuum booster efficiency. If the
trouble persists apply to a service station.
Parking Brake
Every 20,000 Km (and also after the first 2,000-3,000
Km if the car is new) adjust the parking brake.
Correct adjustment of the parking brake ensures
reliable operation of the whole brake system of the car.
Perform adjustment of the parking brake after adjustment of clearances in the rear brakes and
also when the car cannot be braked on a gradient of up to 30 % with the brake lever shifted
through 4-5 teeth of the quadrant.
Parking brake lever travel is adjusted by means of the tensioning device as follows:
•
Shift the lever into the lower- most position and then pull it upwards through two teeth of
the quadrant;
•
Loosen locknut 2 (Fig. 64), and turning adjusting nut 1, tighten the cable;
•
Tighten locknut 2 and check that the car remains braked after shifting the lever through 4-5
teeth of the quadrant.
To prevent shoe-to-drum freezing after travelling over wet roads at sharp fluctuations of
ambient temperature, do not apply the parking brake when leaving the car in a parking lot or a
non-heated garage, unless the brakes are dried by applying them smoothly while driving to the
parking area.
ELECTRICAL EQUIPMENT
The car wiring diagram is shown in Fig. 65. Do not tamper with the car electric circuits.
Additional power consumers should be connected only by qualified electricians at a service
station. To ensure trouble-free operation of the electrical equipment check that the wires are
clean, the contacts in connections are reliable and that the protective rubber caps on the
ignition coil, ignition distributor and spark plugs are sound.
