A brake clip for a disc brake assembly having a brake pad received in an anchor bracket includes a shim configured to be received in the anchor bracket. The shim includes a base leg and opposing upper and lower legs extending from the base leg to define a receiving space. At least one of the upper and lower legs includes a retaining member extending in a first direction. A spring is provided in the receiving space for receiving the brake pad. The spring includes a base and a pair of projections extending from the base. At least one of the projections includes a retaining member that cooperates with the at least one retaining member on the shim to allow for a predetermined amount of relative movement between the shim and the spring in the first direction.

An air disc brake for a road vehicle is proposed, having a mechanism for causing retraction of the brake pads when the brakes are no longer applied, to avoid parasitic drag caused by continued contact of the brake pads against the brake disc. The proposed mechanism includes a pin located in a fixed position relative to one brake pad, and extending through an aperture in the other brake pad. A coil spring is supported on the pin, and pushes the brake pads apart. Where the pin extends through the aperture the extent of the pin provides an indication of the wear state of the pads and disc, which is visible through apertures in the wheel rim.

A disc brake (1) includes a brake disc (2), a brake caliper (3), two brake pads (4, 4′) that are movably guided on the brake caliper (3), a retainer spring (6, 6′) on each brake pad (4, 4′), a retainer bracket (8-8.sup.IV) for pre-tensioning the retainer springs (6, 6′) in relation to the respective brake pad (4, 4′), and an expander spring (10, 10′) that applies an expansion force between the brake pads (4, 4′) and diverging the brake pads (4, 4′). The ends of the expander spring (10, 10′) may bear in each case directly on one of the retainer springs (6, 6′). The disc brake (1) may have a loss prevention device that is operatively connected to the expander spring (10, 10′) such that the expander spring (10, 10′), in the absence of the expansion force, is held on the disc brake (1).

A motor vehicle disc brake assembly comprises a caliper having a cavity, a brake disc rotatable relative to the caliper, a brake lining mounted to the caliper, a piston mounted in the cavity for displacing the brake lining against the brake disc, and an electromechanical actuator for supporting the piston. The electromechanical actuator has a drive assembly operably connected to a spindle, a rotationally restrained spindle nut threaded on the spindle, and an anti-rattle clip coupling together the piston and spindle nut. Rotation of the spindle by the drive assembly moves the spindle nut to support the piston.

Sealing means are disclosed for preventing the ingress of water and dirt between a brake caliper and the carrier guide pin. At the end of the guide pin facing away from the brake carrier, a retaining clip holds a sealing bead of a sealing boot at least partially within an axial bore of the guide pin. At the end of the guide pin which faces towards the carrier, a sealing boot is provided seated on a ring which in turn is attached to the caliper. The other end of the sealing boot is attached to the guide pin, in a space between the guide pin and the ring. The sealing means at either end are compact, and provide effective sealing where there is not enough space to provide known sealing means.

A system is provided for suppressing undesired brake pad motion during brake application, and for installing and removing brake pads utilizing the inventive arrangements. The brake pads and a carrier mount having complementary surface features that retain the brake pad when the brake pad is in its installed position, and a brake pad biasing structure that biases the brake pad in the radially outward direction to bias the contact faces of the mount horn and the brake pad against one another to suppress brake pad kick and vibration and related wear and component fatigue. The radially-outward biasing force may be applied by a spring-loaded plunger located within a bore of a mount horn of the brake pad carrier against a radially-inner surface of a portion of the brake pad extending laterally over the mount horn.

The present disclosure relates to a brake pad, a brake caliper equipped with the brake pad, and a vehicle equipped with the brake caliper. The brake pad may include two brake pad connectors symmetrically positioned with respect to a center of a brake pad surface and connected to the caliper body by springs. Reliability of a return operation of the brake pad is secured, thereby reducing drag and braking noise.

A device for supporting and guiding a brake pad backplate and a brake pad arranged thereon in a pad slot of a disc brake, including a restoring device formed by two separately acting restoring elements. One restoring element is formed by a wire spring which serves to restore the lower portion of the brake pad backplate, while the other restoring element is formed by a pad hold-down spring which is capable of restoring the upper portion of the brake pad backplate.

A brake assembly that includes a brake pad assembly, a pad spring, and a sensor unit. The brake pad assembly includes friction material disposed on a backplate. The pad spring is mounted to the backplate. The sensor unit straddles the backplate and extends from the backplate to the pad spring.

A brake pad retracting device is disclosed. An example vehicle braking system comprising a rotor, and a caliper including a brake pad slidably engaged with a guide pin, and a coil spring through which the guide pin extends, the coil spring having a first end and a second end, the first end having a first inner diameter sized to enable the first end to move freely over a surface of the guide pin, the first end to engage the brake pad to urge the brake pad away from the rotor, and the second end having a second inner diameter sized to frictionally engage the surface of the guide pin, the first inner diameter greater than the second inner diameter.
