Attention! The operation of lifting and placing the vehicle on stands is dangerous! Therefore, before carrying out the operation, read Section Jacking and towing Introduction to leadership.
2. Measure the brake disc thickness at the thinnest point. Service stations use a special caliper for this, for example, HAZET 4956-1 or a micrometer bracket, because the disc has an edge due to wear.
Note. The thickness of the brake disc can also be measured using a conventional vernier caliper, for which it is necessary to place gaskets of the appropriate thickness on both sides of the disc (e.g. two coins). The thickness of the disc in this case is equal to the value obtained minus the thickness of the gaskets.
Attention! The measurement must be taken at several points on the brake disc.
3. The dimensions of the brake disc 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 0.5mm, 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. Reinstall the wheels so that the marks made during removal match. Pre-lubricate with a thin layer of bearing grease the centering belt of the wheel disk on the hub. Do not grease wheel bolts. Replace rusty bolts. Wrap bolts. Lower the car onto the wheels and tighten the bolts crosswise to 110Nm.
