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:
IMPORTANT: Only BMW-approved brake disc lathes may be used!
In the case of stationary brake disc lathes, the BRAKE DISC must be removed.
Mobile brake disc lathe:
IMPORTANT: Only BMW-approved brake disc lathes may be used!
In the case of mobile brake disc lathes, the brake calipers and brake anchor plates must be removed.
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.
