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 15):
A method of compensating brake pad wear in a disc brake, the disc brake having a brake caliper straddling a brake disc, the brake caliper including a rotary lever, a bridge drivable by the rotary lever toward the brake disc, a tappet non-rotatably supported on the bridge, and a wear adjuster, the wear adjuster including a tappet wheel having internal threads engaged with external threads on the tappet, a shaft supported on the bridge and arranged to rotate the tappet wheel, a ratchet wheel non-rotatably arranged on the shaft, and a pawl having a pawl tooth configured to engage a tooth of the ratchet wheel, comprising the acts of:\n rotating the rotary lever in a brake application direction to advance the bridge and the tappet toward the brake disc and to displace the pawl at least until the pawl tooth engages the ratchet wheel tooth; and rotating the rotary lever in a brake release direction after the pawl tooth engages the ratchet wheel tooth to withdraw the bridge from the brake disc and to advance the tappet relative to the bridge toward the brake disc by the pawl tooth driving rotation of the ratchet wheel, the shaft, and the tappet wheel in a wear adjustment direction.
