Disk brake for wheel of vehicle e.g. car, has measurement device to measure displacement of pin guide of caliper, and indicator to indicate state of wear of brake pads from measurement, where pin guide is inserted in cavity of cover

摘要

The brake has a caliper (10) including an actuation unit moving a brake pad relative to the caliper and moving the caliper relative to a cover (11) between rest and braking positions. The brake pad and another brake pad are not in contact with a disk in the rest position. The brake pads are placed against the disk in the braking position to apply a friction force between the pads and the disk. A measurement device measures displacement of a pin guide (30) of the caliper, which is inserted in a cavity (33) of the cover. An indicator indicates state of wear of the pads from the measurement.
