Electrical Circuit Test
1. Disconnect wire from switch terminal and use a jumper
to connect wire to a good ground.
2. Turn ignition key on "On" - warning lamp should
light. If lamp does not light, bulb is burned out or
electrical circuit is defective. Replace bulb or repair
electrical circuit as necessary.
3. When warning lamp lights, turn ignition switch off.
Disconnect jumper and reconnect wire to switch
terminal.
W arning Light Switch Test
1. Raise vehicle on hoist. Attach a bleeder hose to a rear
brake bleed screw and immerse the other end of the
hose in a container partially filled with clean brake
fluid. Be sure master cylinder reservoir is full.
2. Turn ignition switch to " On "; open bleeder screw while
a helper applies moderate pressure to the brake pedal;
warning lamp should light. Close bleeder screw before
helper releases brake pedal. Reapply brake pedal with
moderate-to-heavy pressure; light should go out.
3. Attach the bleeder hose to a front brake bleeder screw
and repeat above test. Warning lamp action should be
the same as in Step No. 2. Turn ignition switch off.
4. If warning lamp does not light during Steps 2 and 3 but
does light when a jumper is connected to ground, the
warning light switch portion of the combination valve is
defective. Do not attempt to disassemble the
combination valve. If any portion of the combination
valve is defective, it must be replaced with a new
combination valve.
5. Lower vehicle to floor. Check and refill master cylinder
to proper level.
Replacement
The combination valve is not repairable and must be
serviced as a complete assembly.
1. Disconnect hydraulic lines at combination valve. Plug
lines to prevent loss of fluid and entrance of dirt.
Disconnect warning switch wiring harness from valve
switch terminal.
2. Remove combination valve.
3. Install combination valve by reversing removal steps.
4. Bleed entire brake system. Do not move vehicle until a
firm brake pedal is obtained.

V A L V E
The height sensing brake proportioning valve, used on
30 series models, provides optimum brake balance and
efficiency. Vehicle braking force is distributed to the front
and rear wheels as defined by light or heavy payload
conditions.
Mounted on the frame, the valve responds to changes in
vehicle trim height as related to rear axle load. Mechanical
linkage connects the valve to a bracket that is attached to
the rear axle.
CAUTION: Adding any suspension accessories or
other equipm ent (such as load leveling kits, air
shocks, suspension lift kits, additional spring leafs,
etc.), or m aking any modification th at w ill change
the distance betw een the axle and the fram e
w ith o u t changing the load, w ill provide a false
reading to the brake proportioning valve. This
could result in unsatisfactory brake performance
which in turn could result in an accident and
possibly personal injury.
Removal
1. Raise vehicle, axle must be allowed to hang free (no
load condition).
2. Clean exterior of valve to prevent dirt from
contaminating hydraulic system when brake pipes are
disconnected.
3. Disconnect brake lines from valve.
If original valve is going to be reinstalled, mark
relationship of the valve shaft to the lever assembly
before removing lever.
4. Remove nut from shaft and remove lever.
5. Remove two screws securing valve to mounting bracket
and remove valve.
Install
1. Install valve on mounting bracket and tighten two
screws.
2. Before installing lever assembly on valve shaft, be sure
all valve brackets, fasteners and links are securely
attached.
3a New Valve. Install lever assembly on valve shaft by
pushing plastic bushing and clip assembly over
serration on valve shaft.
3b. Old Valve. If original valve is being reinstalled, align
lever with mark made on valve at time of removal
before installing bushing and clip assembly on shaft.
4. Install nut on shaft and tighten.
5. Connect brake lines to valve.
6. Bleed brake system
7. Lower vehicle and test brakes.
Lever Assem bly
Replacement
1. Raise vehicle, axle must be allowed to hang free (no
load condition).
2. Mark relationship of the height valve shaft to the
lever assembly.
