Abstract

The invention relates to a disc brake (1), preferably a pneumatic disc brake, in particular for a motor vehicle, comprising a brake disc (2), a brake caliper (6) engaging over the brake disc (2), in which a tensioning device (ZV) is arranged, wherein a respective brake pad (3, 3') is provided on both sides of the brake disc (2), and an adjuster device having at least one adjuster unit (7, 7') foradjusting a friction surface wearing at the brake pads (3, 3') and brake disc (2), wherein the at least one adjuster unit (7, 7') can be operated with a pressure medium independently of the tensioningdevice (ZV). The at least one adjuster unit (7, 7') is designed with a first cylinder unit (ZE1) having a first pressure piston, and with a second cylinder unit (ZE2) having a second pressure piston,wherein the second pressure piston of the second cylinder unit (ZE2) has a piston (16) that is in contact with the brake pad (3, 3'), and an adjuster piston (18) that is arranged on the piston (16).The invention also relates to a method for adjusting a clearance of a disc brake (1).

Description

technical field [0001] The invention relates to a disc brake comprising a readjustment device according to the preamble of claim 1 . The invention also relates to a method for adjusting the play of such a disc brake. Background technique [0002] Vehicles, especially motor vehicles, are equipped with friction brakes in order to convert kinetic energy. Disc brakes are preferred here, particularly in the field of passenger cars and commercial vehicles. Pneumatically actuated disc brakes are also standard equipment in heavy commercial vehicles. [0003] In a typical design of a disc brake, the disc brake comprises a brake caliper with an internal mechanical device comprising generally two brake linings and a brake disc. The cylinder force is introduced via a pneumatically actuated cylinder to the internal mechanism, reinforced by an eccentric and transmitted as a pressing force to the brake pads and brake discs, for example via a threaded spindle, wherein the braking is comp...
