Lada Niva Manual - Maintenance Page 25Adjusting the Free Travel of Brake PedalEvery 20.000 Km (and also after the first 2,000-3,000 Km if the car is new), check andadjust, if necessary, the brake pedal free travel. With the brake system serviceable and theshoe-to-drum clearances of the rear wheels normal, the brake pedal free travel, with the engineshut 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 BoosterEvery 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 pedalpressed, start the engine. With the vacuum booster serviceable, the brake pedal should movefurther down upon starting the engine. If the pedal does not move further down, check fortightness the hose connections to the intake manifold and to the vacuum booster, as looseconnections cause in leakage of air and sharply reduce vacuum booster efficiency. If thetrouble persists apply to a service station.Parking BrakeEvery 20,000 Km (and also after the first 2,000-3,000Km if the car is new) adjust the parking brake.Correct adjustment of the parking brake ensuresreliable operation of the whole brake system of the car.Perform adjustment of the parking brake after adjustment of clearances in the rear brakes andalso when the car cannot be braked on a gradient of up to 30 % with the brake lever shiftedthrough 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 ofthe 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 4-5teeth of the quadrant.To prevent shoe-to-drum freezing after travelling over wet roads at sharp fluctuations ofambient temperature, do not apply the parking brake when leaving the car in a parking lot or anon-heated garage, unless the brakes are dried by applying them smoothly while driving to theparking area.ELECTRICAL EQUIPMENTThe 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 servicestation. To ensure trouble-free operation of the electrical equipment check that the wires areclean, the contacts in connections are reliable and that the protective rubber caps on theignition coil, ignition distributor and spark plugs are sound.Fig 64.
