To stabilise the position of the suspension units, exert pressure on them by pushing down
first the rear and then the front bumpers for 2-3 times, applying a force of about 400-500 N
(40-50 kg). To determine wheel camber, measure distance C (Fig. 55) between the wheel rim
and the set square. Then roll the car to turn the wheels through 180", and measure distance D.
Camber is correct if distance D is 1-5 mm greater than distance C. Camber is adjusted by
changing the number of shims 20 (Fig. 51) between the upper wishbone shaft and the cross
member. Check and adjust toe-in only after checking and adjusting the wheel camber.

To determine toe-in, measure distance A (Fig. 55) between the corresponding points on the
front wheel rims. Then roll the car to turn its wheels through 180" and measure distance D is
1-5 mm greater than distance C.
Camber is adjusted by changing the number of shims 20 (Fig 51) between the upper
wishbone shaft and the cross member.
Check and adjust toe-in, measure distance A (Fig 55) between the
corresponding points on the front wheel rims. Then roll the car to turn
its' wheels through 180 degrees and measure distance B. Toe-in is
correct, if the first dimension is 2-4 mm greater than the second one.
Toe-in is adjusted by changing the length of side steering rods 3
(Fig. 56). For this purpose loosen clamps 2 and turn adjusting sleeves
1 through the same number of revolutions in the opposite directions,
thus screwing the sleeves on or off and changing the length of the
side steering rods. Adjustment over, tighten clamps 2 to a torque of 19 N · m (1.9 kg · m) so
that their slots face down and their ends, after tightening, do not touch each other.

Camber and toe-in can be also checked and adjusted, though less accurately, with the car
unloaded. In this case wheel camber D-C should be from -1 to +3 mm, and toe-in A-B should
be 4~1 mm.
BRAKES
Brake Hydraulic System
The brake system of the car is given in Pig. 57. Prior to servicing the brake system, clean
each brake of dirt, wash it with warm water and dry with compressed air.
Never use gasoline, diesel fuel, trichloroethylene or other mineral solvents for the purpose
since they attack the cups and seals of the hydraulic cylinders.
The surfaces of the brake linings should be clean, with no traces of dirt or lubricant. Soiled
linings should be cleaned with a wire brush and washed with white spirit. If the pads or
linings are contaminated with oil, check for oil or brake fluid leakage through the seals and
eliminate the defect. During the maintenance ope- rations take care to protect the brakes from
oil.
If free travel of the brake pedal exceeds 5 mm with the engine stopped, or the braking
efficiency of the wheels becomes different, per- form an all-round check of the brake system.
