Abstract
Abstract A vehicle brake apparatus for attachment to the axle of a vehicle having a rotatable disc attached so as to rotate with the wheel of a vehicle and having flanges carried by a housing attached to the axle of the vehicle so that a brakeshoe carried by brakeshoe carrier telescopes in the flanges attached to the axle housing for driving a brake lining on the brakeshoe against he rotating disc. Bearings riding between the brakeshoe carrier and flanges allow the telescoping action when a torque is placed on the brakeshoe.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
A disc brake apparatus for a vehicle comprising in combination: a. axle means attached to a vehicle; b. rotatable disc means adapted to be fixedly attached to a vehicle wheel for rotation therewith; c. brakeshoe means slidably connected to said axle means, said brakeshoe means having a plurality of protruding brakeshoe carriers; d. a brake housing attached to said axle means and including a plurality of axle flanges each flange forming a bore therein on at least one side of said disc means and adapted for said brakeshoe carrier to slidably telescope therein; e. a plurality of bearing means located between each said brakeshoe carrier and each said flange on said brake housing adapted to allow telescoping of said brakeshoe means while having torque placed thereon; f. actuating means fixedly attached to said brakeshoe housing for actuating said brakeshoe carriers and thereby forcing said brakeshoe means towards said disc means; and g. brake lining means attached to said brake shoe means and adapted to frictionally engage said disc means whereby actuation of said actuating means will telescope said brake shoe means having brake lining means attached thereto into frictional contact with said disc means to apply braking force to the inter-connected wheel.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
53 words
The apparatus in accordance with claim 1 in which said brake shoe means with said brake lining means attached thereto includes brake shoes with brake linings located on either side of said disc means, each said brake lining being an annular metallic plate Lining adapted for a 360* engagement with said disc means.
Claim 4
Dependent Claim
31 words
The apparatus in accordance with claim 2 but including a spring actuated return means for applying a force to said brake shoe means opposite to that applied by said actuating means.
Claim 5
Dependent Claim
25 words
The apparatus in accordance with claim 1 in which said brake shoe means has spaced openings therein to allow the free circulation of air therein.
Claim 6
Dependent Claim
31 words
The apparatus in accordance with claim 4 including camming means for camming said brakeshoe means into engagement with said disc means by actuation of a cable connected to said camming means.
Claim 7
Dependent Claim
27 words
The apparatus in accordance with claim 5 in which said flanges on said brake housing and said brakeshoe carrier are grooved with bearings located in said grooves.
Claim 8
Dependent Claim
15 words
The apparatus in accordance with claim 6 in which said actuating means is pneumatically operated.
