DIAGNOSIS AND TESTING (Continued)
Fig. 27 Proportioning Valve Locations On HCU
(2) Remove hydraulic brake line (Fig. 27) from pro-
portioning valve controlling the rear wheel of the
vehicle which has premature wheel skid.
(3) Then remove proportioning valve from that
outlet port of the HCU.
CAUTION: Be sure the pressure test fitting being
installed into the HCU, has the correct thread sizes
for installation into the HCU and installation of the
proportioning valve.
(4) Install Pressure Test Fitting, Special Tool
6805-1 or 6805-2 into the outlet port of the HCU.
(5) Install proportioning valve into pressure test
fitting installed in the HCU outlet port.
CAUTION: Be sure the pressure test fitting being
installed into proportioning valve, has the correct
thread sizes for installation into the proportioning
valve and installation of brake tube fitting into pro-
portioning valve.

(6) Install Pressure Test Fitting, Special Tool
6805-3 or 6805-4 into the outlet of the proportioning
valve.
(7) Connect brake hydraulic line onto pressure test
fitting installed in proportioning valve.
(8) Install
C-4007-A into each pressure test fitting. Bleed air out
of hose from pressure test fitting to pressure gauge,
at pressure gauge to remove all trapped air.
(9) With the aid of a helper, apply pressure to the
brake pedal until reading on proportioning valve
inlet gauge, is at the pressure shown on the following
chart. Then check the pressure reading on the pro-
portioning valve outlet gauge. If proportioning valve
outlet pressure does not agree with value shown on
the following chart, when inlet pressure shown on
chart is obtained, replace the proportioning valve. If
proportioning valve is within pressure specifications
do not replace proportioning valve.
(10) Check rear wheel brake shoe linings for con-
tamination or for replacement brake shoes not meet-
ing OEM brake lining material specifications. These
conditions can also be a possible cause for a prema-
ture rear wheel skid.
(11) Install proportioning valve in HCU and hand
tighten until proportioning is fully installed and
O-ring seal is seated into HCU. Then torque propor-
tioning valve to 40 N·m (30 ft. lbs.).
(12) Install brake tube on proportioning valve.
Torque tube nut to 17 N·m (145 in-lbs.) torque.
(13) Bleed the affected brake line. See Bleeding
Brake System in the Service Adjustments section of
the manual for proper bleeding procedure.
