A drum brake for a motor vehicle has a pocket for collecting abraded brake particles. The pocket is accessible from above via an opening. After the introduction of a suction device into the opening, the abraded brake particles can be extracted by suction. Pollution of the environment with abraded brake particles is thereby avoided.

A spreader unit for a drum brake is provided with a readjustment device which ensures that the clearance remains substantially constant even in the case of wear on the brake linings. The readjustment device is arranged between actuating pistons and changes the spacing of the actuating pistons in at least one readjustment step when an actuating travel of the first and second brake shoe holders has exceeded a travel setpoint value. A thermally actuable blocking device mechanically prevents the execution of the readjustment step by the readjustment device at a temperature above a temperature setpoint value

An electronic parking brake device including: a plate part having a brake shoe rotatably mounted thereon; a housing part mounted on the plate part and configured to guide hydraulic pressure; a motor part mounted on the housing part, and driven when power is applied thereto; a piston part mounted on the housing part, and moved by hydraulic pressure so as to operate the brake shoe; and an operation part embedded in the housing part, disposed between the piston parts, and driven by the motor part so as to push the piston parts.

The disclosure concerns a Drum brake assembly (10) for a motor vehicle,

the drum brake assembly (10) having: a brake drum housing (16); at least one brake shoe (26); a brake lining (18);
wherein the brake lining (18) is arranged at an inner circumferential face (24) of the brake drum housing (16) and the brake shoe (26) is displaceable relative to the brake lining (18), so as to contact the brake lining (18) during braking. Also disclosed is a drake drum assembly (14) for a motor vehicle Method a for producing such a brake drum assembly (14).

A farm implement is provided having a frame and first and second track assemblies for assisting in moving the farm implement along a ground surface in a line of travel. The first track assembly and the second track assembly are positioned on opposite lateral sides of the frame. The first track assembly has a first track frame, a first idler wheel, and a first brake assembly. The first idler wheel has an inboard side facing toward a center of the first track frame and an outboard side facing away from the center the first track frame. The first brake assembly has a first disc coupled to the first idler wheel on the outboard side of the first idler wheel, a first caliper couplable to first and second sides of the first disc, and a first torque arm coupled to the first track frame and a spindle of the first idler wheel. The first caliper is mounted on the first torque arm, and the first caliper is configured to clamp down on the first and second sides of the first disc in order to slow and/or stop rotation of the first idler wheel.

The present invention relates drum brake system, comprising a back plate assembly and a brake drum (1) that is rotatable with respect to the back plate assembly, the back plate assembly comprising: a back plate (2); two brake shoes (3, 3′), the two brake shoes (3, 3′) being pivotably connected to the back plate (2), pivot axes (4, 4′) of the brake shoes (3, 3′) being disposed at or near first ends of the brake shoes (3, 3′); an actuator housing (5) with two pistons (6, 6′), the two pistons (6, 6′) being configured to move outwardly, to press each piston (6, 6′) against one of the brake shoes (3, 3′) to pivot the respective brake shoe (3, 3′) outwardly about its pivot axis (4, 4′), and to press the respective brake shoe (3, 3′) against the brake drum (1) for braking; a return spring (7) extending between the brake shoes (3, 3′) and being connected to both brake shoes (3, 3′), the return spring (7) being configured (7) to exert a retracting spring force that pulls both brake shoes (3, 3′) away from the brake drum; two tension springs (8, 8′) and a holder arrangement (9), inner ends of each of the two tension springs (8, 8′) being connected to the holder arrangement (9), an outer end of the first tension spring (8) of the two tension springs (8, 8′) being connected to a first brake shoe (3) of the two brake shoes (3, 3′) and an outer end of the second tension spring (8′) of the two tension springs (8, 8′) being connected to a second brake shoe (3′) of the two brake shoes (3, 3′).
