A motor-vehicle fixed-caliper partially lined disk brake with pin mounting for backing plates of disk brake linings, comprising a one-piece clearance spring with two spring legs which are elastically clamped in between the backing plates on a bearing portion which is free of friction material.

A friction lining holding spring and the equipped component/assembly, specifically a motor vehicle disc brake lining, including the friction lining holding spring. The friction lining holding spring includes an offset knee piece of a U-spring leg, which branches off at an angle from a largely flat U base section, and wherein the largely flat base section has a fastening tab with a cup-shaped rim hole including a through-opening for the purpose of fixing on a backplate of the friction lining, wherein each knee piece has integrated gearing, which is in particular designed as an uneven brake piston insertion trajectory such that, when a brake piston is inserted, there is a predefined gearing reduction effect for the purpose of automatically influencing or modelling the necessary force requirement.

An assembly that includes a parking brake system including two or more spindle/nut devices. The two or more spindle/nut devices include a high efficiency device and a low efficiency device. The high efficiency device is in communication with a first end of a brake pad, and the low efficiency device in communication with a second end of the brake pad. The high efficiency device moves the first end of the brake pad against a braking surface, and the low efficiency device moves the second end of the brake pad against the braking surface. After one or both of the ends of the brake pad are moved against the braking surface and a clamping force is created, the low efficiency device locks and prevents movement of the high efficiency device so that the clamping force is maintained.

The invention relates to an actuating device for an internal shoe brake, including an automatic adjusting device with an adjusting lever which includes a guide track in the form of a guiding slot with two opposing track surfaces which cooperate with opposing sides of a housing-fixed guide element in order to convert a displacement of the adjusting lever relative to the housing-fixed guide element into pivoting movements of the adjusting lever.

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 brake assembly has a brake disc in rotational engagement with a wheel of a vehicle, a brake pad which frictionally engages the brake disc when an actuator force is applied thereto, an actuator having an output shaft driven in a forward direction and a reverse direction in order to bring the brake pad and brake disc into the frictional engagement, and an energy absorption and/or storage unit. The energy absorption and/or storage unit absorbs forces acting on the output shaft in the reverse direction in case of a predetermined operation situation.

The proposal is for an improved expansion device for a drum brake having an integrated readjustment unit having a readjusting screw which can be locked therein by a spring-loaded latching unit which, for a reliable readjustment function with a reduced level of force, provides for the latching unit to allow a defined idle rotation of the readjusting screw, which is defined structurally by a first stop acting in a first direction of revolution and a second stop acting in the opposite direction of revolution.

A brake lining retention device for a disc brake of a motor vehicle. The brake lining retention device includes a brake carrier fixed at the vehicle side and having a lining shaft for receiving a brake lining, wherein the lining shaft is delimited at the brake disc leading side in relation to a main rotation direction of the brake disc and delimited at the brake disc trailing side by a lining horn-like member of the brake carrier. The brake lining retention device includes a brake lining guided in the lining shaft and has a lining retention member and a friction lining fixed thereto, and a resilient element supported on a lining horn-like member and a support face of the lining retention member, wherein the face is adjacent to the lining horn-like member and the resilient element is inserted in a recess of the lining retention member.
