MECHANICALLY ADJUSTABLE WEAR INDICATOR

摘要

The invention relates to a wear indicator (11) for a vehicle brake, for example. The indicator has an adjustable measuring rod (12) which can be inserted into a cavity (14) in a brake housing (2), so that one end abuts against the brake piston (4) and the other end protrudes from the brake housing. When the brake is engaged, the length of the measuring rod (12) can be calibrated by means of a calibrating cap (27, 30) to a predetermined starting value corresponding to new friction linings.
