Abstract:
A disc brake, a wear adjuster for a disc brake and a method for operating a disc brake are provided. The wear adjuster includes a pawl biased by a spring against, and actuated by, a rotary lever, a shaft with the ratchet wheel arranged to be rotated by the pawl when the rotary lever rotates in a brake release direction, and a tappet wheel threaded on a brake application tappet supported on a movable bridge in the disc brake caliper. During brake release the pawl rotates the ratchet wheel and the shaft. The shaft and the tappet wheel have gearing which rotates the tappet wheel with the shaft. Due to the threaded engagement of the tappet wheel and the non-rotating tappet, the rotating tappet wheel causes the tappet to advance relative to the bridge to compensate for brake pad wear.

Claim (Index 1):
A disc brake, comprising:\n a brake caliper configured to straddle a brake disc, the brake caliper including\n a rotary lever; \n a bridge drivable by the rotary lever toward the brake disc when the rotary lever rotates in a brake application direction; \n a tappet supported on the bridge; and \n a wear adjuster including\n a tappet wheel rotatably arranged on the tappet, \n a shaft supported on the bridge and configured to rotate the tappet wheel, \n a ratchet wheel non-rotatably arranged on the shaft, and \n a pawl drivable by the rotary lever toward the brake disc when the rotary lever rotates in a brake application direction, the pawl having a pawl tooth configured to engage a tooth of the ratchet wheel, \n \n wherein\n the tappet wheel is configured to cooperate with the bridge to advance the tappet toward the brake disc when the rotary lever advances the bridge toward the brake disc, \n the pawl is arranged such that after the pawl tooth engages the ratchet wheel tooth during rotation of the rotary lever in the brake application direction, during rotation of the rotary lever in a brake release direction the pawl rotates the ratchet wheel and the shaft in a wear adjustment direction, \n the shaft is configured to drive the tappet wheel to advance the tappet toward the brake disc relative to the bridge when the shaft rotates in the wear adjustment direction.
