This invention relates to an improved vehicle wheel hub and bearing unit assembly and method for producing the same wherein an outer brake rotor mounting surface of the wheel hub and bearing assembly is subjected to a microfinishing process. The method for producing the vehicle wheel hub and bearing assembly comprises the steps of: (a) providing a vehicle wheel hub including an inboard end, an outboard end, and a main body having a radially outwardly extending flange, the flange having an outer surface which defines an outer brake rotor mounting surface of the vehicle wheel hub; (b) providing a bearing unit to rotatably support the vehicle wheel hub relative thereto; (c) assembling the bearing unit onto the vehicle wheel hub to produce a vehicle wheel hub and bearing unit assembly which defines a longitudinal axis; (d) preloading the bearing unit; (e) providing a microfinishing assembly having a microfinishing wheel; (f) supporting the vehicle wheel hub and bearing assembly on the microfinishing fixture; and (g) operating the microfinishing fixture whereby the microfinishing wheel engages the outer brake rotor mounting surface of the vehicle wheel hub and bearing unit assembly to produce a finished vehicle wheel hub and bearing assembly, the outer brake rotor mounting surface of the finished vehicle wheel and bearing unit assembly being microfinished relative to the longitudinal axis of the vehicle wheel hub and bearing unit assembly.

A friction pad assembly and backing plate therefor features a pair of opposing upper and lower abutments, with the engagement surface of the lower abutments being recessed by a predetermined magnitude relative to the engagement surfaces of the upper abutments. The lower abutments are recessed relative to the upper abutments, such that lower abutments will not contact the bracket which supports the friction pad assembly under resting and light braking conditions. However, the lower abutments at the pressured end of the friction pad assembly will come into contact with the caliper bracket during heavy braking conditions in order to reduce the load on the upper abutment. While the force applied by the pad to the bracket support structure under these conditions may cause the un-pressured end of the friction pad assembly to lift slightly, the clearance thereby produced will be too small to cause perceptible clacking noise upon brake release.

A dispenser mechanism attachable to a plastic soft drink bottle to permit measured liquid quantities to be dispensed from the bottle. A cradle type support is provided for positioning the bottle in an inverted tilted condition within a refrigerator. Liquid can be dispensed from the bottle without removing the bottle from the refrigerator.
