PURPOSE:To simplify a brake adjustment work by controlling the compressed air fed frorm a compressor to an expansion cylinder which actuates a brake pedal by use of a magnetic air control unit. CONSTITUTION:An electromagnetic oil pressure transfer unit D and oil pressure limit units E, F are connected with pipes and pressure hoses between an oil pressure pump B driven by a motor C and an expansion unit A driven by an oil pressure. Next, a transfer switch lever 32 which is engaged with the movement of a piston rod 28 is fitted to the tip of the piston rod 28 of the electromagnetic oil pressure transfer unit D, and is connected to the circuit of the motor C and the oil pressure limit switch. Then, by operating a switch 70 of the electromagnetic oil pressure transfer unit D, the expansion unit A is engaged with the movement system of the brake pedal. |
