Attention! The operation of lifting and installing the car on stands is associated with danger! Therefore, before carrying out the operation, read the Section Jacking and towing Introduction to the manual.
2. Measure the thickness of the brake disc at its thinnest point. Service stations use a special caliper for this, for example, HAZET 4956-1 or a micrometer bracket, since the disc has an edge due to wear.
Note: The thickness of the brake disc can also be measured using a regular caliper, for which it is necessary to place spacers of the appropriate thickness on both sides of the disc (for example, two coins). The thickness of the disk in this case is equal to the obtained value minus the thickness of the gaskets.
Attention! The measurement must be taken at several points on the brake disc.
3. The brake disc dimensions are given in the Specifications.
4. If the wear limit is reached, the brake disc must be replaced.
5. If there are large cracks or grooves deeper than 0.5 mm, the brake disc must be replaced.
Note: Ventilated brake discs with hairline cracks up to 25 mm long do not need to be replaced.

6. Install the wheels so that the marks made during removal match. Pre-lubricate the centering belt of the wheel disk on the hub with a thin layer of bearing grease. Do not lubricate the wheel mounting bolts. Replace rusty bolts. Tighten the bolts. Lower the car onto the wheels and tighten the bolts crosswise to 110 Nm.
