Chippings on the friction surfaces (A)
Chippings on edge of brake disk ring (B)
Chippings on perforation holes (C)

Chippings on the friction surfaces (A)

Chippings on the friction surfaces (A) can occur because of thermal stresses. A max. of 3 chippings up to a size of 400 mm and a depth of max. 2 mm are permissible for each brake disk.

Chippings on edge of brake disk ring (B)

Chippings on the edge of the brake disk ring (B) can occur because of thermal stresses or collisions. A maximum of 3 chippings of the following dimensions are permissible for each brake disk:

Length in circumferential direction max. 25 mm
Width in direction of friction surface max. 8 mm
Depth max. 3 mm

Chippings on perforation holes (C)

Chippings on perforation holes (C) can occur because of thermal stresses. They are permissible up to a length, width and depth of 3 mm in each case.
