A backing plate and associated brake pad that includes a reinforcement plate and a retention plate. The reinforcement plate has an outboard surface, an inboard surface, and a mold hole. The retention plate has an outboard surface, an inboard surface, and a locking projection that cooperates with the mold hole of the reinforcement plate to mechanically lock the retention plate to the reinforcement plate so that the inboard surface of the reinforcement plate faces the outboard surface of the retention plate. A dampening layer may be included between the reinforcement plate and the retention plate.

Brake pad backing plate

A one-piece sheet metal combination retainer and anchor for use in a non-servo floating shoe drum brake assembly () having a pair of laterally extending ears () for axially retaining respective ends () of a pair of brake shoes (), and a pair of rivet head reinforceable axially extending portions () for anchoring the brake shoe ends during brake application. A base portion () has one or more rivet () or shaft () receiving apertures with the each of the axially extending portions abutted by a rivet head flat surface (). The base portion has a transversely extending central region () to provide, in conjunction with a brake assembly backing plate (), a parking brake cable () retaining clamp.

Combined retainer and anchor for floating shoe drum brake

In order to realize a two-piston floating caliper disc brake with a wide caliper, the axially outer side of the caliper is supported by radially extending protrusions shaped on the outer brake shoe. While the two protrusions have the same depth, they differ in their width. Corresponding circular grooves within the caliper around recess openings on the opposite side of the brake cylinders, however, are identical. Therefore, a radial support of the brake caliper can be carried out by both protrusions while a tangential positioning of the caliper is limited to the wider one of the two protrusions.

Disc brake, disc brake caliper and disc brake shoe

A composite brake adapter for a caliper disc brake assembly is made up of a first pre-stamped part of a sheet of metal adapted to match an axle housing of the assembly, and of a second part cast onto an upper surface of the first part to adhere thereto, additional structural elements providing matching of the second part with a caliper of the assembly being made an integral part of the second part. A method of making a composite brake adapter for a caliper disc brake assembly comprises the steps of providing a first part of the adapter, the first part being provided with mounting holes to match an axle housing of the assembly and being made of a sheet of metal; placing the first part into a mold, and casting a second part of the adapter into the mold onto a surface of the first part. To incorporate additional structural elements of the adapter with a caliper of the assembly, the additional structural elements are placed into a precision fixture and secured within the mold prior to casting the second part.

Composite brake adapter

A vehicular brake assembly comprises brake shoes and a brake disc. The brake shoes are fastened to a sheet plate and mounted inside an inner drum portion of the brake disc. The brake disc is operatively connected to an axle placed within a stationary axle housing that carries a mounting flange. The sheet plate is fastened to the mounting flange. An anchor pin is attached to the mounting flange and an opening is made in the sheet plate for the anchor pin to project therethrough to thereby serve as an abutment surface for the brake shoes transferring any force exerted on the brake shoes directly to the mounting flange. The brake disc is operatively engaged with a caliper adapted to grip an outward portion of the brake disc. The caliper slides are provided on the mounting flange to receive the caliper. A method of making a flange for the braking structure comprises the steps of having a flange intended to match an axle housing and preferably made as a pre-stamped metal sheet part, the flange being provided with mounting holes; placing the prefabricated flange into a form (mold); and casting an anchor pin and caliper slides onto respective surfaces of the flange.

Rear knuckle with brake features

A disc brake for a motor vehicle includes a rotor mounted to a wheel and rotatable about a first axis therewith; a pair of parallel-spaced pins removably mounted to the vehicle chassis so as to extend in a direction generally parallel to the first axis; a pair of brake shoes having slots for receiving the pins on either side of the rotor so as to place brake linings respectively mounted on the pins in opposition with complementary annular friction surfaces on either side of the rotor; and a caliper slidably supported by the two pins so as to straddle the rotor and both brake shoes, respectively. The slots of the brake shoes are defined in part by a finger configured to deflect responsive to a brake load and the deflection of the finger enables the sequential engagement of the brake shoes against the pins.

Pin guided push-pull caliper

A modular pin mounted caliper assembly is provided for use in a disc brake. The modular caliper assembly can be angled with one or more other modular caliper assemblies. Each caliper segment has a housing with a piston disposed in an inboard portion thereof for movement in an axial direction. A pair of flanges extend from opposite sides of the housing and are axially offset from each other enabling the connection and alignment of a plurality of segments. The resulting caliper can be used in a wide variety of vehicles despite changes in brake torque requirements. The modular caliper assembly includes a plurality of inboard and outboard brake shoe pairs. Each brake shoe has a pair of pin engaging features extending from opposite outboard ends of the brake shoe. Like the caliper segment flanges, the pin engaging features are axially offset from one another, enabling the shoes to be overlapped on common pins.
