Caution: To better assess the thickness of the brake pads, remove the wheels.
1. Before you begin disassembling, you should mark the relative position of the wheel with the wheel hub.
2. After unscrewing the wheel mounting bolts, remove the wheel ("a" – the wear limit of the brake shoe linings is 7 mm, including the support plate).
3. If the measured brake lining thickness value is below 7mm, then it is absolutely necessary to change the brake linings for the entire axle (repair operation).
4. After installing the wheels in the marked position, tighten the wheel mounting bolts with a tightening torque of 120 Nm.
Attention! After changing the brake shoe linings, press the brake system control pedal firmly several times with the vehicle stopped so that the brake shoe linings enter the position corresponding to the working condition.
