REMOVE
(1) Disconnect the negative (ground) cable from
the battery and isolate cable.
(2) Using a brake pedal depressor, move and lock
the brake pedal to a position past the first inch of
pedal travel.This will prevent brake fluid from
draining out of the master cylinder when the
brake tubes are removed from the HCU.
(3) Raise vehicle. Vehicle is to be raised and sup-
ported on jackstands or on a frame contact type
hoist. See Hoisting in the Lubrication And Mainte-
nance section of this service manual.
CAUTION: Do not apply a 12 volt power source to
any terminals of the 25 way HCU connector when
disconnected.
(4) Remove the 25 way connector (Fig. 25) from
the CAB located on the bottom of the HCU. The 25
way connector is removed from the CAB using the
following procedure. Grasp the lock on the 25 way
connector (Fig. 25) and pull it as far out as possible
(Fig. 26). This will unlock and raise the 25 way con-
nector from the socket on the CAB.
CAUTION: Before removing the brake tubes from
the HCU, the HCU must be thoroughly cleaned. This
must be done to prevent dirt particles from falling
into the ports of HCU or entering the brake tubes.
(5) Thoroughly clean all surfaces of the HCU, and
all brake tube nuts located on the HCU. Use only a
solvent such as Mopar Brake Parts Cleaner or an
equivalent to clean the HCU.
