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 brake pad retainer system in a vehicle disc brake comprises a calliper bridge and a calliper housing supporting brake pads on either side of a rotary brake disc, wherein the system is arranged to hold one brake pad in position relative to the calliper bridge. The retainer system comprises a retainer bracket arranged parallel to the brake disc axis and extending across a back plate of the brake pad, and a retaining spring arranged along a radially outer portion of the back plate and extending between the retainer bracket and the back plate. The retainer bracket has an angled surface arranged in contact with a corresponding first angled surface on the retaining spring. The retaining spring has a second angled surface arranged in contact with a corresponding angled surface on the radially outer portion of the back plate. The disclosure also relates to a brake pad.

A disc brake assembly that includes a brake caliper, a retainer strap, and a sensor assembly. The retainer strap is mounted to the brake caliper and extends across a brake pad assembly. The sensor assembly is mounted to the retainer strap and generates a signal indicative of a position of the brake pad assembly.

A disk brake includes a brake caliper and two brake pads, which can be pressed onto a brake disk on both sides and which each have a pad carrier plate and a friction pad fastened thereto. A pad retaining clip, which is retained on the brake caliper and which spans an installation opening, is supported on the brake pads. The pad retaining clip is fastened to a form closure element of at least one brake pad so as to be secured against movement.

A brake caliper for a bicycle includes a housing configured to be installed on the bicycle, the bicycle including a disc attached to a wheel of the bicycle. A brake pad is installed within the housing and is configured to move between a braking position and a non-braking position. The braking position is a location within the housing where the brake pad contacts the disc when the housing is installed on the bicycle. The non-braking position is a location within the housing where the brake pad is further from the disc than in the braking position. The caliper also includes a biasing member configured to bias the brake pad in a downstream direction within the housing with the brake pad is in the non-braking position, the downstream direction being parallel to a direction of rotation of the disc when a wheel of the bicycle is rotating to move the bicycle forward.

A guiding means for a brake lining arrangement of a disc brake, comprising a main part which comprises a guiding portion provided for guiding a guiding projection of the brake lining arrangement and which comprises a fixing portion which is used to fix the guiding means to a brake support. The fixing portion has two contact surfaces and a stop surface which connects the two contact surfaces. At least one elastic retaining bracket is provided on the stop surface, the retaining bracket being in secure engagement with the brake support at least in some sections, and at least the stop surface is provided with a retaining portion which can be brought into contact with the brake support at least in some sections.

A pad support spring includes a U-shaped portion comprising an outer peripheral surface portion, an inner peripheral surface portion and a linking surface portion. The U-shaped portion is configured to include: a pad holding portion; a cutout portion provided by cutting out a part from the linking surface portion toward the inner peripheral surface portion; a tongue piece portion which in an unassembled state has a base end formed by the cutout portion on the outer peripheral surface portion side of the pad holding portion and a distal end which projects out from an opposing surface of the inner peripheral surface portion, and which in an assembled state deforms elastically to press a brake pad in conjunction with the U-shaped portion; and a first slit portion provided by cutting out part of a first linking part.

A disc brake includes a brake pad, a retaining spring, and a retaining bracket. The retaining bracket pretensions the retaining spring radially inwardly relative to a rotation axis of a brake against the brake pad. A smallest radial distance (D) of the retaining spring from the brake pad in a region in which the retaining bracket overlaps the retaining spring in a radial direction is greater than a smallest radial distance (d) of the retaining bracket from the brake pad in a region in which the retaining bracket overlaps the brake pad in the radial direction.

A disc brake includes a brake caliper, a brake pad, a retaining spring holding the brake pad in a radial direction relative to a brake axis, a retaining bracket pretensioning the retaining spring in the radial direction, a first holder on the brake caliper configured to support the retaining bracket towards a radial outside, and a second holder on the brake caliper configured to support the retaining bracket radially towards the radial outside but not in an axial direction, the second holder comprising a stop. At least one of the first holder or the second holder has a stop acting in a first axial direction. The retaining bracket has at least one of a first protrusion that rests on the retaining spring in a second axial direction opposite the first axial direction and a second protrusion that rests on the brake caliper in the second axial direction.

An apparatus and method are provided for suppressing undesired brake pad motion during brake application, and for installing and removing brake pads utilizing the inventive arrangements. One embodiment of the invention includes 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 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.
