Proportioning Valve
- Install 2 pressure gauges, that will measure to at least 2000 psi (140.6 kg/cm2 ), to input and output sides of proportioning valve. See Fig 1.
- Measure both input and output pressure with brakes applied. See Fig 2. If measured pressures are not within specification, replace proportioning valve. See PROPORTIONING VALVE TEST SPECIFICATIONS table. DO NOT disassemble proportioning valve.
