Before starting work
Push the parking brake lever all the way down (the car is disinhibited).
Hang the rear wheel and rotate it; if the wheel touches the pads, bring them together with the adjusting nut of the spacer bar (see subsection 3.34). Remove the rear wheel.
The clearance in the rear wheel hub bearings should be 0.02-0.13 mm.
The maximum allowable gap is 0.2 mm.
Recommendation: Measure the gap with a gauge.
If there is no indicator, shake the suspended wheel in a vertical plane. If you feel play, then you need to adjust the clearance in the bearings.
Remove the wheel hub cap.
Unbend the cotter pin and remove it from the hub axle hole.
Tighten the nut with a torque wrench to 20 Nm (2 kgf·m), while turning the drum in both directions to self-align the bearings.
While holding the drum from turning, loosen the nut and re-tighten the nut to 7 Nm (0.7 kgf·m).
Unscrew the nut until the nearest slot of the nut is aligned with the hole in the axle for the cotter pin, insert the cotter pin and bend its ends.
Install the protective cap by putting 25 g of Litol-24 lubricant into it. If you have brought the pads apart, spread them apart and adjust the gaps between the pads and the brake drum (see subsection 3.34).
