GENERAL INFORMATION

Models with back drum brakes

Arrangement of an adjusting nut with a nozzle of the regulator of a cable of the emergency brake on models with the SOHC engine

The optimum gap between brake shoes and the brake drum is supported by the mechanism of automatic adjustment, however at long operation of the car the cable of the emergency brake stretches therefore the course of the lever of the emergency brake increases.

PERFORMANCE ORDER
1. Lift a back part of the car and record on supports.
2. Completely release the emergency brake.
3. Turn an adjusting nut with a nozzle on the regulator of a cable of the emergency brake which is installed on a back beam so that brake shoes began to brake the brake drum at a provorachivaniye of a back wheel (see rice. An arrangement of an adjusting nut with a nozzle of the regulator of a cable of the emergency brake on models with the SOHC engine).
4. Rotating an adjusting nut in the opposite direction, take away on insignificant distance brake shoes from the brake drum.
5. The emergency brake has to slow down back wheels when moving the lever of the emergency brake of the second tooth of a ratchet.
6. After adjustment check that cable of the emergency brake move smoothly and without jammings. Apply on a regulator carving a thin film of lubricant to protect it from corrosion.
7. Lower the car on the earth.

Models with back disk brakes

Use of the screw-driver for rotation of a wheel of an adjusting level on models with back disk brakes

PERFORMANCE ORDER
1. In the presence take off caps of wheels, then weaken bolts of fastening of back wheels. Lift a back part of the car and record on supports. Remove back wheels.
2. Move the lever of the emergency brake on the second tooth of a ratchet.
3. On models with DOHC engines with the catalyst unscrew four nuts and remove the thermofilter of the central section of the exhaust system.
4. On models with the SOHC engine weaken an adjusting nut with a nozzle on the regulator of a cable of the emergency brake installed on a back beam.
5. On models with DOHC engines weaken the nut fixing the compensator of a cable of the emergency brake to draft of the lever of the emergency brake.
6. The screw-driver through an adjusting opening of a brake disk / nave (see rice. Use of the screw-driver for rotation of a wheel of an adjusting level on models with back disk brakes) turn a wheel of an adjusting level so that brake shoes began to brake a brake disk.
7. Turn a wheel of an adjusting level in the opposite direction in order that brake shoes departed on insignificant distance from a brake disk / nave.
8. Make similar adjustment on the second back wheel.
9. Rotating, move a nut on the regulator or the compensator of a cable of the emergency brake to situation at which the emergency brake will slow down wheels. Check that the emergency brake slows down at the same time two back wheels.
10. Completely lower the lever of the emergency brake, then repeatedly tighten it.
11. Zatormazhivaniye of back wheels of the car has to occur at a raising of the lever of the emergency brake on the sixth tooth of a ratchet. If necessary, rotating a nut on the regulator or the compensator of a cable of the emergency brake, establish a nut in such situation that the zatormazhivaniye of back wheels occurred when tightening the lever of the emergency brake on the sixth tooth of a ratchet.
12. In the presence install the thermofilter of the exhaust system.
13. Establish wheels and lower the car on the earth. Tighten bolts of fastening of a wheel the required moment.
