ESP DODGE NEON 2000 Service User Guide

The in-line proportioning valves used on this vehi-
cle require special pressure fittings to test the pro-
portioning valves for proper proportioning valve
function. The pressure fittings are installed before
and after the proportioning valve being tested to ver-
ify proportioning valve is maintaining the required
hydraulic pressure to the rear wheel brake which it
controls.
The testing of proportioning valves for this vehicle,
if equipped with ABS, can be found in the
ANTILOCK BRAKE SYSTEM section.
PROPORTIONING VALVE TEST
The test procedure is the same for either rear pro-
portioning valve. After road testing the vehicle to
determine which wheel skids first, follow the proce-
dure below for testing the suspect proportioning
valve.
(1) Using a brake pedal holding tool as shown (Fig.
22), depress the brake pedal past its first one inch of
travel and hold it in this position. This will isolate
the master cylinder from the brake hydraulic system
and will not allow the brake fluid to drain out of the
master cylinder reservoir.
(2) Use the figure shown to determine which pro-
portioning valve needs to be tested (Fig. 21).
(3) Remove the hydraulic brake tube from the pro-
portioning valve controlling the rear wheel of the
vehicle that has premature wheel skid.
(4) Remove the proportioning valve from its outlet
port on the master cylinder.CAUTION: Be sure the pressure test fittings being
installed into master cylinder and proportioning
valve, have the correct thread sizes needed.
(5) Install the Brake Pressure Adapters, Special
Tool 8644 and 6805-3 onto the proportioning valve
(Fig. 23).
(6) Install the proportioning valve (with tools) back
into the outlet port on the master cylinder.
(7) Attach a Pressure Gauge, Special Tool
C-4007-A, to each pressure adapter (Fig. 24).
(8) Remove the brake pedal holding tool. Bleed any
air out of the pressure gauge hoses at the pressure
gauge.
(9) With the aid of a helper, apply pressure to the
brake pedal until the reading on proportioning valve
inlet gauge is at the target inlet pressure shown in
the BRAKE PROPORTIONING VALVE APPLICA-
TIONS AND PRESSURE SPECIFICATIONS table

DIAGNOSIS AND TESTING (Continued)

CAUTION: Before removing the master cylinder
cap, wipe it clean to prevent dirt and other foreign
matter from dropping into the master cylinder res-
ervoir.
CAUTION: Use only MoparTbrake fluid or an equiv-
alent from a fresh, tightly sealed container. Brake
fluid must conform to DOT 3 specifications.
Do not pump the brake pedal at any time while
having a bleeder screw open during the bleeding pro-
cess. This will only increase the amount of air in the
system and make additional bleeding necessary.
Do not allow the master cylinder reservoir to run
out of brake fluid while bleeding the system. An
empty reservoir will allow additional air into the
brake system. Check the fluid level frequently and
add fluid as needed.
The following wheel circuit sequence for bleeding
the brake hydraulic system should be used to ensure
adequate removal of all trapped air from the hydrau-
lic system.
²Left rear wheel
²Right front wheel
²Right rear wheel
²Left front wheel
MANUAL BLEEDING
NOTE: To bleed the brakes manually, the aid of a
helper will be required.
(1) Attach a clear plastic hose to the bleeder screw
and feed the hose into a clear jar containing enough
fresh brake fluid to submerge the end of the hose
(Fig. 26).
(2) Have a helper pump the brake pedal three or
four times and hold it in the down position.
(3) With the pedal in the down position, open the
bleeder screw at least 1 full turn.
(4) Once the brake pedal has dropped, close the
bleeder screw. After the bleeder screw is closed,
release the brake pedal.
(5) Repeat the above steps until all trapped air is
removed from that wheel circuit (usually four or five
times).
(6) Bleed the remaining wheel circuits in the same
manner until all air is removed from the brake sys-
tem. Monitor the fluid level in the master cylinder
reservoir to make sure it does not go dry.
(7) Check the brake pedal travel. If pedal travel is
excessive or has not been improved, some air may
still be trapped in the system. Rebleed the brakes as
necessary.
(8) Test drive the vehicle to verify the brakes are
operating properly and pedal feel is correct.
PRESSURE BLEEDING
NOTE: Follow pressure bleeder manufacturer's
instructions for use of pressure bleeding equip-
ment.
Following the same wheel circuit sequence as pre-
scribed for manual bleeding.
(1) Attach Adapter, Special Tool 6921, to the mas-
ter cylinder reservoir (Fig. 27).

SERVICE PROCEDURES (Continued)

DOUBLE INVERTED TUBING FLARES
After preparing the tubing using the procedure in
PREPARING THE BRAKE TUBE FOR FLARING,
make a double inverted tubing flare using the follow-
ing procedure (Fig. 31).
CAUTION: When using brake tubing with Nygal
coating, always use flare nuts designed for this
coating. They have a larger hole in the center to
accommodate the coating on the tube.
(1) Install the replacement flare nut on the tube so
the threads are facing the flare yet to be made (Fig.
32).
(2) Open the Flaring Tool, Special Tool C-4047 (or
an equivalent), separating the tools vertical posts.
(3) Place the tubing in the jawed hole between the
two vertical posts.
(4) Slowly bring the vertical posts together captur-
ing the tube between the halves. Leave enough tub-
ing sticking through the top of the vertical posts to
allow for flaring. Apply only enough pressure to hold
the tube in place.

BRAKE DRUM MACHINING
If a brake drum is deeply scored or warped, it can
be machined on a brake lathe equipped to machine
brake drums. Follow the manufacturers instructions
on the machining procedure.
Measure the brake drum diameter before machin-
ing. If machining the drum will cause the drum to
exceed maximum allowable diameter, do not machine
the brake drum. It needs to be replaced.
CAUTION: Do not machine the brake drum if it will
cause the drum to exceed maximum allowable
diameter.
All brake drums are marked with the maximum
allowable brake drum diameter (Fig. 35).
When machining, make sure the final finish feed
cut is fine in order to avoid a screw effect on the
brake shoes when the brakes are applied. This finalfeed cut specification varies from lathe manufacturer
to lathe manufacturer.
