Brake Proportioning/Combination Valve: Testing and Inspection
Fig 36 Type 3 Proportioning Valve Test Fittings
The in-line proportioning valves used in this system require special pressure fittings set No. 6805, or equivalent, to test for proper valve function. The
fittings are installed before and after the proportioning valve being tested to verify valve is maintaining the required hydraulic pressure to the rear wheel
brake which it controls. The pressure gauges used for testing the in-line proportioning valves on both non-ABS and ABS systems is Pressure Gauge Set
No. C-4007-A, or equivalent.
If a condition of premature wheel skid occurs on a vehicle, the proportioning valve should always be tested prior to being replaced as there are
conditions other than a faulty proportioning valve that can cause premature wheel skid, such as worn, contaminated or improper brake linings.
