Abstract

A brake installation for a motor vehicle. First and second pressure provision devices build up brake pressure in the wheel brakes. The first pressure device connected to a first wheel brake of a first brake circuit and to a second wheel brake of the first brake circuit. The second pressure device connected to a third wheel brake of a second brake circuit and to a fourth wheel brake of the second brake circuit. Each pressure device is respectively activated by an open-loop/closed-loop control unit. A first hydraulic line, with a normally open isolating valve, connects the first wheel brake line of the first brake circuit to the first wheel brake line of the second brake circuit. A second hydraulic line, with a normally open isolating valve, connects the second wheel brake line of the first brake circuit to the second wheel brake line of the second brake circuit.
