Component: Service Brakes, Hydraulic:foundation Components:hoses, Lines/piping, And Fittings
Manufactured by: Chrysler Corporation
Affected Units:: 1,400
Due to improper material construction the hydro-boost fluid return hose may not be capable of withstanding the temperatures and/or pressures experienced with the hydro-boost system. Also, the hydro-boost fluid high pressure hose assembly may have been mislocated, allowing the assembly to contact the frame side rail. Abrasion resulting from continued contact along with improper material construction may cause pressure hose failure. Either of these conditions may cause hydro-boost fluid leakage, resulting in the loss of power assist for the steering and braking systems. Complete loss of steering or braking will not occur since both systems would revert to manual operation.
The dealer will install a hydro-boost fluid return hose constructed form the proper material, positioning the hose assembly to ensure adequate clearance between it and the frame side rail.
Vehicle description: light trucks. System: service brakes; hydro boost system. Consequences of defect: increased steering effort and increased stoppingdistances can result in loss of vehicle control and an accident.
