2. Mark the position of the wheel disk relative to the hub so that the balanced wheel can be installed in its original position.
3. Loosen the wheel nuts of the vehicle while it is standing on the ground.
4. Raise the front of the vehicle.
5. Remove the wheel.
6. Cars from 10/89 issue, except for "station wagon" models: Screw on 2 wheel nuts to ensure the brake disc is properly centered.
7. Measure the thickness of the brake disc. In workshops, a special gauge or micrometer is used for this, since wear on the brake disc causes an edge to form. The thickness of the disc can also be measured with a regular caliper, but a shim of known thickness should be placed on each side of the disc. To determine the exact thickness of the disc, the total thickness of the shims should be subtracted from the obtained value.
Attention! Measurements must be taken at several points on the disk.

8. If the wear limit has been reached, the brake disc must be replaced. For wear limit, see Section Technical data of the brake system
9. If there are large cracks and grooves deeper than 0.5 mm, the brake disc should be replaced.
10. If there is a dial indicator, measure the lateral runout of the brake disc in the installed state. Set the indicator to the outer edge. Required value: maximum lateral runout 0.1 mm. Excessive lateral runout may be caused by a broken hub bearing, contact a workshop for inspection.
11. If necessary, unscrew the wheel nuts.
12. Screw on the wheel, taking into account the mark on the hub. Lower the car and tighten the wheel nuts crosswise with force 100 Nm.
