FIELD: measuring equipment.
SUBSTANCE: invention belongs to area of brake systems inspection. The device for diagnostics of a pneumatic-hydraulic brake drive contains a strain gauge sensor of air pressure (2), installed into an air route of the pneumatic-hydraulic booster (3), a piezo-quartz sensor with a magnetic case (5), installed during diagnostics onto a brake drum, an ultrasonic sensor of registration of pistons movement (4) in the pneumatic-hydraulic booster, a braking automatic device (1), a measuring device (6) with a liquid crystal display.
EFFECT: registration of time of operation of a brake drive, reliability increase is reached.
