Abstract
A method for forming a brake assembly for a motor vehicle includes a wheel hub, a knuckle, and a brake rotor. The wheel hub includes a neck portion and a flange portion having a flange face. The flange face has a plurality of bolt receiving holes formed therein. The wheel hub is placed in rotational communication with the knuckle. The flange face of the wheel hub has a brake rotor secured thereto. The brake rotor has an inner surface, which is subjected to final finishing in order to reduce lateral run-out of the brake rotor.
Claims17
A method of finishing a brake rotor assembly, the method comprising:
- providing a knuckle, a brake rotor, and a hub;
- assembling said knuckle, said brake rotor, and said hub together to form an assembly;
- clamping said assembly in a fixture;
- finishing at least one surface of said brake rotor to reduce lateral run-out of said surface of said brake rotor to less than 14 μm wherein the assembly is clamped in the fixture during the finishing of the brake rotor wherein the finishing occurs prior to mounting of said brake rotor assembly to a vehicle.
A method of manufacturing a brake assembly, said method comprising:
- providing a knuckle, a brake rotor, and a hub;
- assembling said knuckle, said brake rotor, and said hub together to form an assembly;
- fixing said assembly to a fixture wherein said hub is driven such that said hub and said brake rotor rotate with respect to said knuckle;
- and
- finishing at least one surface of said brake rotor to reduce lateral run-out of said surface of said brake rotor wherein the rotor is finished while assembled to the knuckle and the hub and further wherein the finishing occurs prior to mounting of said brake rotor assembly to a vehicle.
A method of finishing a brake rotor, said method comprising:
- providing a knuckle, a hub, and a brake rotor, said brake rotor having an outer contact surface and an inner contact surface;
- assembling said knuckle, said hub, and said brake rotor to form a brake rotor assembly;
- securing said brake rotor assembly;
- rotating said brake rotor with respect to said knuckle;
- finishing said inner and outer contact surfaces of said brake rotor to have lateral run-out of less than 14 μm while the brake rotor is assembled to the knuckle and the hub wherein the finishing occurs prior to mounting of said brake rotor assembly to a vehicle.
