Grand Caravan FWD V6-3.3L VIN 3 Flex Fuel (2002)
Brake Hose/Line: Description and Operation
DESCRIPTION - BRAKE TUBES AND HOSES
The brake tubes are steel with a corrosion-resistant nylon coating applied to the external surfaces. The flex hoses are made of reinforced rubber with
fittings at each end.
The primary and secondary brake tubes leading from the master cylinder to the ABS ICU Hydraulic Control Unit (HCU) or the non-ABS junction
block have a special flexible section. This flexible section is required due to cradle movement while the vehicle is in motion (The ICU and non-ABS
junction block are mounted to the cradle). If replacement of these lines is necessary, only the original factory brake line containing the flexible section
must be used.
OPERATION - BRAKE TUBES AND HOSES
The purpose of the chassis brake tubes and flex hoses is to transfer the pressurized brake fluid developed 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 suspension.
