Abstract
Abstract A disc brake is disclosed which includes a U-shaped fixed support straddling a rotary disc and two pads supported by an axial pin attached to said support at one radial and thereof. Clamping means are associated with the fixed support to apply the pads against the respective faces of the disc. The pin is located at the outside of the periphery of the disc, and two radial abutting surfaces are provided on each arm of said radial end of the support. These abutting surfaces are situated on each side of a plane passing by the pin and perpendicular to the radial plane passing by the pin for permitting each of the pads to anchor by one of its radial edges on one or the other of the abutting surfaces, according to the direction of disc rotation. Each pad comprises a lug extending radially at the outside of the periphery of the disc along said radial edge, the pin extending through this lug.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
183 words
In a disc brake: a rotor having a pair of friction faces; a U-shaped fixed support straddling said rotor and presenting a pair of legs extending generally parallel to each of said friction faces, a pin carried by said fixed support at one edge of each of said legs, said pin extending across said rotor in a direction generally parellel to the axis of the rotor, a pair of friction elements mounted on said pin adjacent each of said friction faces, said one edge of each of said legs having a pair of bearing surfaces for anchoring its corresponding friction element, said pair of bearing surfaces being located in alignment on opposite sides of a plane intersecting said pin and perpendicular to a plane extending along a radius of the rotor and intersecting said pin so that each friction element anchors on one of said surfaces or the other of said surfaces, depending upon the direction of rotation of the rotor, and a clamping member slidably mounted on said fixed support for urging said friction elements into engagement with their corresponding friction faces.
Claim 2
Dependent Claim
183 words
In a disc brake: a rotor having a pair of friction faces; a U-shaped fixed support straddling said rotor and presenting a pair of legs extending generally parallel to each of said friction faces, a pin carried by said fixed support at one edge of each of said legs, said pin extending across said rotor in a direction generally parellel to the axis of the rotor, a pair of friction elements mounted on said pin adjacent each of said friction faces, said one edge of each of said legs having a pair of bearing surfaces for anchoring its corresponding friction element, said pair of bearing surfaces being located in alignment on opposite sides of a plane intersecting said pin and perpendicular to a plane extending along a radius of the rotor and intersecting said pin so that each friction element anchors on one of said surfaces or the other of said surfaces, depending upon the direction of rotation of the rotor, and a clamping member slidably mounted on said fixed support for urging said friction elements into engagement with their corresponding friction faces.
Claim 3
Dependent Claim
45 words
The invention of claim 1, wherein each leg of said support is formed with axially extending bent portions connected by portions parallel to the plane of the rotor, each of said pair of bearing surfaces comprising at least one of said axially extending bent portions.
Claim 4
Dependent Claim
24 words
The invention of claim 1, wherein said pin and said bearing surfaces are disposed in a plane extending along a radius of said rotor.
Claim 5
Dependent Claim
23 words
The invention of claim 1, and column means secured to said fixed support, said clamping member being slidably mounted on said column means.
Claim 6
Dependent Claim
15 words
The invention of claim 4, wherein said clamping member is mounted on only one column.
Claim 7
Dependent Claim
33 words
The invention of claim 5, and a noise reducing spring disposed between said friction elements and said clamping member, said spring yieldably urging said clamping member radially outwardly with respect to said rotor.
