Disk brake unit caliper mounting

Claim 1

A disk type vehicle wheel brake unit comprising: a. stationary support plate means having a main part formed with a pair of ear portions each having a substantially T-shaped cross-section; b. aperture means extending through each of said ear portions; c. a circular opening formed through said main part in spaced relation to said ears; d. C-shaped caliper means disposed in straddling relation to said main part and both of said ear portions and comprising first and second legs with actuator means disposed in said first legs; e. tie bolt means secured to said legs and extending through said aperture means for sliding movement relative to said support plate means; f. a pair of spaced apart resilient seals disposed between said tie bolt means and said aperture means; g. a first friction pad stationarily mounted on said second leg; h. a second friction pad slidably mounted in said circular openings for enegagement by said actuator means; i. said pair of tie bolt means extending parallel to the axis of said circular opening and having at least a portion thereof positioned inside of the outline of said circular opening as defined by two parallel lines tangent to opposite sides of said opening to act as a tension means opposed against an expanding force applied to said caliper means during brake application; j. said caliper means acting as a compression means opposed against an expanding force developing in said caliper means during brake application; and k. said ear portions, tie bolt means and said resilient seals being positioned in a substantially enclosed space defined by said C-shaped calliper means and said friction pads.
