BRAKE LINES

DESCRIPTION - BRAKE TUBES AND HOSES
The chassis brake tubes are steel with a corrosion
resistant coating applied to the external surfaces.
The flex hoses are made of reinforced rubber.
All available brake systems on this vehicle use the
same type of brake line fittings and tubing flares.
The brake line fittings used are double-wall ISO style
tubing flares and fittings at all tubing joint locations.
Only the outlets of the proportioning valves and the
rear flex hoses threading into them have non-ISO
style flares (ABS and early production Non-ABS
vehicles only). They utilize double-inverted style
flares. Refer to (Fig. 10) for specific joint locations
and tube fitting size.
Brake hose connections at disc brake calipers are
made using banjo fittings permanently attached to
the end of the hose. Banjo bolts with internal pas-
sageways for fluid flow connect the hose to the cali-
per. Copper washers are used to seal the banjo

OPERATION - BRAKE TUBES AND HOSES
The purpose of the chassis brake tubes and flex
hoses is to transfer the pressurized brake fluid devel-
oped by the master cylinder to the wheel brakes of
the vehicle. The flex hoses are made of rubber to
allow for the movement of the vehicle's steering and
suspension.
