34 11 667 Precision-turning Both Front Brake Discs On Both Sides
WARNING: This page is about a different car, the 2010 BMW X5, 2009 BMW X5, 2008 BMW X5, and 2007 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
Always precision-turn both sides of both brake discs on one axle.
Observe Max. machining dimension per friction ring side Minimum brake disc thickness (MIN TH). See 34 11 FRONT BRAKE E70 .
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). See 34 11 FRONT BRAKE E70

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.
Please refer to the lathe manufacturer's instruction manual for the exact procedure.
Mobile brake disc lathe:
IMPORTANT:
Only BMW-approved brake disc lathes may be used!
In the case of mobile brake disc lathes, only the brake caliper has must be removed.
The brake discs remain on the car.
Please refer to the lathe manufacturer's instruction manual for the exact procedure.
After fine-grinding the brake discs, measure the thickness difference inside the braking surfaces at 8 points with an external micrometer. See 34 11 FRONT BRAKE E70 .
