Abstract: A disc brake having a support member that is secured to a vehicle with first and second bores that are perpendicular to a rotor and a caliper with an actuation section having a piston for applying an actuation force to move friction members into engagement with the rotor. A first guide pin, affixed to the caliper having a first bearing surface and a second guide pin, affixed to the caliper having a second bearing surface that respectively engage the first bore and second bore in a plane along the center of gravity of the caliper. The center of gravity of the caliper is sustained by compensating for any change in a relationship of a piston and an actuation chamber by adding additional fluid to the actuation chamber on movement of the piston out of the actuation chamber such that an actuation force is always perpendicularly applied to the rotor.

Abstract: A spacer secured to a dash panel offsets a boost unit of a brake system into an engine compartment. The spacer has a cylindrical body with a u-shaped space through which air from the engine compartment is communicated to the boost unit to effect a brake application. The u-shaped space is divided by a plurality of walls into first and second labyrinth paths around the cylindrical body. An open cell gasket is located between the boost unit and the spacer to seal the u-shaped space. Air enters the u-shaped space and is divided into equal volumes that flow around the cylindrical body to a radial opening in the cylindrical body for distribution to the boost unit. Air flowing along the first and second labyrinth paths encounters the open cell gasket and sounds generated in the engine compartment are attenuated by being absorbed prior to delivery to the boost unit.

Abstract: A disc brake having a support member with first and second spaced apart rails that extends toward a rotor to position first and second friction members adjacent corresponding sides of the rotor. The support member has a horizontal projection that extends away from the rotor with a first bore therein to receive a piston connected to the first friction member and a peripheral surface thereon that is received in a second bore in a caliper to define a second piston that is connected to the second friction member. The first piston, horizontal projection and second bore define an actuation chamber that receives pressurized fluid to develop an actuation force to move the first and second friction members into engagement with the rotor and effect a brake application. Retraction seals act on and move the first and second friction members away from the rotor to define a same running clearance.

Abstract: A corner assembly for a vehicle having a wheel hub and a rotor wherein the rotor may freely translate axially with respect to the wheel hub during a brake application and as a result any vibrations created on the engagement of friction pads with the rotor are not introduced into a stationary support by way of the wheel hub not sensed by a person in the vehicle.

Abstract: A disc brake has a support with a first end separated from a second end by first and second side walls that retain actuation members to move the first and second friction members into engagement with a rotor and effect a brake application. First and second perpendicular projections that extend from the support are aligned with the first wall and third and fourth perpendicular projections that extend from the support and are aligned with the second wall. The first and second friction members have first and second radial projections located between a first end and a second end. Beams connect the radial projections with the perpendicular projections to align the first and second friction members with the rotor and pivot on the perpendicular projections to carry reaction forces created during a brake application into the first end of the support.

Abstract: A brake booster having a first shell joined to a second shell through a flange (26) on the first shell and a peripheral surface (204) on the second shell. Axial slots (36,36?, . . . 36n) on the flange that extend from an opened end toward a shoulder engage radial slots (38,38?, . . . 38n) to create a first plurality of arcuate projections (40,40?, . . . 40n) that are sequentially separated from a second plurality of arcuate projections (42,42?, . . . 42n). Each arcuate projection (40) has parallel sides that extend from a radial plane (11) on the flange while each arcuate projection (42) has first and second radial tabs (44, 46) thereon. Each arcuate projection (40) is deformed into sealing engagement with an edge (206) on the peripheral surface (204) to position the peripheral surface (204) under the flange while creating an axial gap (x) between the radial tabs (44,46) and the edge (206) to provide a visual inspection of the sealing engagement.
