Brake Disc: Testing and Inspection
Chrysler Disc System - Type 2
Fig 2 Disc Measuring Points
PURPOSE
In the manufacturing of the brake rotor all the tolerances regarding surface finish, parallelism, and lateral runout are held very closely. The
maintenance of these tolerances provide the surface necessary to prevent brake roughness.
Light scoring of the rotor surface not in excess of 0.38 mm (0.015-inch) in depth is normal. This condition does not affect the brake operation.
Some discoloration or wear of the disc surface is normal and does not require re-surfacing when linings are replaced.
