2008 Chevrolet Aveo Brake Disc

The proper way is to remove the caliper assembly without disconnecting the brake hoses, remove the caliper bracket, remove the rotor-to-front wheel hub detent screw from the rotor and the front wheel hub, and then pull off the rotor.

The proper way is to inspect the rotor, install the rotor to the front wheel hub by tightening the detent screw, install the caliper bracket, and then install the caliper assembly.

The geometry and composition of the Pro-Cut tips are designed for °single pass° cutting. When using the Pro-Cut the cutting depth should be set to take all material needed to get below rust grooves, eliminate all run-out and resurface the entire disc in a single pass. Cuts of 0.1016-0.381 mm (0.004-0.015 in) will provide the best surface finish and the optimal tip life. No °skim cut° or °finish cut° is needed. Failure to follow this procedure will shorten tip life. The Pro-cut tips will last between 7-12 cuts per corner. With three usable corners, a pair of tips is good for at least 21 cuts.

GM Service and GM Brake Engineering have performed competitive evaluations on a significant number of bench and on-car brake lathes. These tests measured critical performance characteristics such as flatness, surface finish, and the ability of the lathe to repeat accuracy over many uses. In each test, single-pass lathe designs outperformed the competitors. Single-pass brake lathes are more productive requiring less time to perform the same procedure.
