2. Mark the position of the disc relative to the hub with paint in order to set the balanced wheel to its original position.
3. Place the machine on stands.
4. Remove wheel.
5. Measure the brake disc thickness. In factories, a special template or micrometer is used for this, since a shoulder forms when the disc wears. You can measure the thickness of the brake disc and an ordinary caliper. In this case, on both sides of the brake disc, it is necessary to install the appropriate thickness of the gasket.
6. In order to obtain the exact thickness of the brake disc, it is necessary to subtract the thickness of the gaskets from the measured size.
Attention! Take measurements in several places.
7. Brake disc dimensions are given in subsection 7.2.
8. Always replace two brake discs, even if only one of the discs has reached the wear limit.
9. If there are large marks or grooves deeper than 0.5 mm, replace the brake disc.
