Attention! Brake discs made of composite materials cannot be machined.
Brake discs are always ground on both wheels on both sides for one axle, observing the roughness (cleanliness of processing) working surface - 0.5-3.5 microns and the minimum thickness of the front / rear disc - 28.4 / 18.4 mm.
It is allowed to remove no more than 0.4 mm from each side of the disk.
Only one set of brake pads may be used on a disc of minimum thickness.
Remove discs, grinding of brake discs must be carried out on machines (pic. 11.31) in the workshop, strictly following the operating instructions for the machine.
