Protruding portions protruding in a direction of approaching a disc rotor are integrally formed in a locking plate portion of a pad spring. Moreover, an insulating resin coating is formed on a front surface side (surface in a region opposed to an outer peripheral surface of the disc rotor) of the locking plate portion. The coating film formed on the front surface of the locking plate portion flows downward by its own weight before the coating material is solidified. As a result, the coating film formed on bottom surfaces (front surfaces of protrusions) of the protruding portions is thinner in film thickness than that of the coating film in other region.

A brake pad, a disc brake, and a method of fitting a brake pad. At least one of a first brake pad and a second brake pad and corresponding support structures may have complementary profiles on circumferential faces thereof arranged so as to permit the brake pad to be inserted into a corresponding support structure in a transverse direction of the brake pad and at an angle to a circumferential direction of the support structure.

A brake pad for a heavy vehicle disc brake and a disc brake. The brake pad defines a first and second circumferential surfaces. A first spring forms at least part of the first circumferential surface and is arranged to contact the first circumferential pad abutment surface and urge the brake pad, in use, towards the second circumferential pad abutment surface.

A brake pad for a heavy vehicle disc brake. The brake pad may include a layer of friction material and first and second resilient arms. The first and second resilient arms may be arranged to contact first and second corresponding pad abutment structures to urge the brake pad away from a rotor when the brake pad is urged towards the rotor during application of the brake.

In some examples, a brake assembly is configured to compress a brake disc stack to reduce and/or limit rotational motion of a wheel about a wheel axis. The brake assembly is configured to transmit a compression force on the disc stack to a backing plate. The backing plate is configured to transmit the compression force to a torque tube via one or more torque pads. A torque pad includes a pin supported by a support portion of the torque pad. The pin is configured to insert into a support recess of a boss when the boss supports the torque pad. The support portion of the torque pad is resiliently biased, such that the support portion exerts an force on the pin in an inward direction when the pin is displaced in an outward direction opposite the inward direction.

The invention relates to a disc brake caliper (100) comprising: a caliper body (10) placed astride the disc of a disc brake, fitted with a pair of half-bodies (11, 12) connected to each other by means of a first and a second end bridge (20, 21) adapted to delimit a central aperture (22) of the caliper body (10), and by means of a first (13) and a second (14) connection bridge placed astride the disc of the disc brake at such a central aperture (22). The caliper body (10) houses brake pads (2, 3) supported by suspension pins for pads (4, 4, 5, 5) arranged in an axial direction (X-X) of the caliper body; said pads have a first side (42) facing the disc of the disc brake connected to an opposite second side (44) by means of a corner (43) facing said central aperture (22). Such a caliper (100) further comprises a first (50) and a second (51) cross-shaped leaf springs to influence the pads (2, 3) in the axial direction (X-X), wherein such a first (50)/second (51) spring is adapted to act between the pads (2, 3) and between the first/second connection bridge (13, 14) and the first/second end bridge (20, 21) of the half-bodies (11, 12). The first (50)/second (51) leaf spring comprises a bow-shaped longitudinal beam (61) having a shaped first end (73) adapted to be removably constrained to the first/second connection bridge (13, 14) and an opposite shaped second end (74) adapted to be removably constrained to the first/second end bridge (20, 21). Wherein each of such first (50) and second (51) leaf springs comprises: a cross beam (62) connected to the longitudinal beam (61) at a central base portion (64) of the spring, to influence the pads (2, 3) at suspension portions of the pads (2, 3) towards the pins (4, 4, 5, 5), such a cross beam (62) includes wings (81, 82) projecting from the central base portion (64) of the spring in the axial direction (X-X); each of such wings (81, 82) has a surface (7) facing the disc of the disc brake suitable for resting on the corner (43) of the respective pad (2, 3); each of said wings (81, 82) comprising first means for influencing the pads (8, 83, 84) to influence the second side (44) of the pad (2, 3) by keeping it away from an inner wall (90) of the half-bodies (11, 12); each of such wings (81, 82) comprises second means for influencing the pads (

A disc brake for heavy vehicles. The disc brake may include first and second brake pads, a caliper, and at least one support. The caliper may have a radial opening and a pad strap. The support may support a rear face of at least one of the brake pads and may have a guide formation that may be configured to engage the pad strap and restrict rotation of the brake pad about a radial axis.

The disk brake device comprises a caliper body including a cylinder part and a pawl part having a notch section connected together by a center bridge and side bridges with notch sections each interposed between the center bridge and side bridges, a support including guide pin guiding parts each interposed between the cylinder part and pawl part, guide pins respectively slidable to the guide pin guiding parts, and an outer side brake pad threadedly engaged with such surface of the pawl part as is opposed to a rotor on the rotor turn-in and turn-out sides of the notch section.

A motor vehicle disc brake includes a cover with two tiered bores of parallel axes, each bore includes at least one first section; a caliper slidably mounted axially with respect to the cover by two pins of parallel axes rigidly connected to the caliper and each including at least one guiding section which is slidably mounted, with a radial clearance, in the tiered bore of the cover; and brake, wherein a cylindrical outer guiding surface of the sliding guiding section of each pin includes at least two opposed axial portions, extending angularly about the axis of each pin according to an angle less than 90, a median axial plane of the two portions being parallel with a plane passing through the axes of the two pins.

A device comprising a connection plate having a first end and a second end and two or more spring arms connected to and extending from the second end of the connection plate at an angle and having a portion that extends back toward the connection plate, wherein the two or more spring arms, when moved during a brake apply, provide an axial force toward the connection plate. The device may be used within a brake assembly, which further includes a caliper; a support bracket having a leading end and a trailing end, wherein the leading end, the trailing end, or both, have one or more projections; a rotor extending through the support bracket; and two or more brake pads located within the support bracket on opposing sides of the rotor.
