into hot areas. All tubes should be properly attached
with recommended retaining clips.
Care must be taken during the removal and re-
placement of components on a vehicle equipped with
Anti-Lock brakes. To avoid damage to the flexible
stainless steel hoses between the master cylinder and
Anti-Lock hydraulic control unit.
HYDRAULIC BRAKE LINE TUBING FLARES
All available brake systems used on L.H. platform
vehicles use ONLY ISO STYLE TUBING FLARES
(FIG. 2) at all hydraulic tubing to component loca-
tions. Except the rear drum brake flex hose to
wheel cylinder connection.
CAUTION: ALWAYS USE THE PROPER TYPE OF ISO
FLARING TOOL AND REQUIRED PROCEDURE,
WHEN TUBE FLARING IS REQUIRED WHEN SER-
VICING THE VEHICLES HYDRAULIC BRAKE SYS-
TEM. THIS IS REQUIRED TO ENSURE THE INTEG-
RITY OF THE VEHICLE'S HYDRAULIC BRAKING

SYSTEM.

TO REPAIR OR FLARE TUBING (I.S.O. STYLE)
Using Tubing Cutter, Special Tool C-3478-A or
equivalent, cut off damaged seat on tubing (Fig. 3).
Ream out any burrs or rough edges showing on inside
of tubing. This will make the ends of tubing square
(Fig. 4) and ensure better seating of flared end tub-
ing. PLACE TUBE NUT ON TUBING BEFORE
FLARING THE TUBING.
ISO TUBING FLARE
CAUTION: All ISO style tubing flares (Fig. 2) are of
metric dimensions. When performing any service
procedures on a vehicle using ISO style tubing
flares, metric size tubing of 4.75 mm MUST be used
with metric ISO tube flaring equipment.

Fig. 3 Cutting and Flaring of Brake Line Tubing
Fig. 4 Brake Tube Preparation For Flaring
To create a (metric) ISO style tubing flare, Use
Snap-On Flaring Tool TFM-428, (Fig. 3) or equiva-
lent. See (Fig. 5) and proceed with the steps listed
below. Be sure to place the tubing nut on tube
before proceeding to flare the tubing.
(1) Carefully prepare the end of the tubing to be
flared. Be sure the end of the tubing to be flared is
square and all burrs on the inside of the tubing are
removed (Fig. 4). This preparation is essential to
obtain the correct form of a (metric) ISO tubing
flare.
(2) Open the jaws of the Flaring Tool. Align the
mating size jaws of the flaring tool around the size of
the tubing to be flared. Close the jaws of the Flaring
Tool around the tubing to keep it from sliding out of
the flaring tool, but do not lock the tubing in place.
