Emptying pressure medium from hydraulic unit of motor vehicle braking system involves removing valve coil, passing compressed air through hydraulic unit to displace pressure medium

摘要

The method involves removing the coil from at least one valve (25), which is closed by its permanent magnet, connecting the hydraulic unit (34) on the main (11) or wheel brake cylinder (16,17) side to an air supply of adequate pressure and passing air from the source through the hydraulic unit to displace the pressure medium, which is collected.
