Claim:
An elevator installation having an elevator car, which moves in a vertical direction along guide tracks and which in the case of need is braked or held at standstill by braking equipment, the braking equipment including at least two brake units, each of the brake units having brake plates which co-operate with a brake track when the brake units are actuated, the braking equipment comprising: one of the at least two brake units including a wear-compensating device which on release of said one brake unit after actuation sets a clearance between the brake plates of said one brake unit and the brake track in correspondence with a substantially constant value, wherein said wear-compensating device sets a desired fixed clearance between a fixed one of said brake plates and the brake track; and wherein said one brake unit includes a brake housing and a guide support connected to said brake housing by said wear-compensating device, and said wear-compensating device includes a positioning part that is connected by a slip connection or a detent connection with one of said brake housing and said guide support and which is mutually connected by way of a slide connection with another of said guide support and said brake housing, wherein said slide connection enables relative sliding between said brake housing and said guide support in correspondence with a desired clearance between one of said brake plates and the brake track and a relative slipping in said slip connection takes place when said desired clearance is exceeded.
