IMPORTANT: Always precision-turn both sides of both brake discs on one axle.
Maximum machining dimension per friction ring side is 0.8 mm! Observe MINIMUM BRAKE DISC THICKNESS (MIN TH).
Brake discs of M models (Compound brake discs) must not be machined! Only one brake pad set may be used up on brake discs which have been lathe-turned to minimum thickness (MIN TH).
Stationary brake disc lathe:

The brake discs remain on the vehicle.
After fine-grinding the brake discs, measure the THICKNESS DIFFERENCE inside the braking surfaces at 8 points with an external caliper gauge.
