Date: 900201
Description
No. 486
February, 1991
To: All Jeep-Eagle and Dodge Dealers
Subject:
Safety Recall # 486 -- Front Brake Hoses and Left Rear Brake Tube
Models:
1988, 1989 and 1990 Model Year Eagle Premier and 1990 Dodge Monaco Passenger Cars Built Before May, 1990.
The front brake hoses and the left rear brake tube on certain of the vehicles listed above may be subject to damage from two separate problems, both
affecting the brake hydraulic system:
1.
Front wheel brake hose routing on all of the listed vehicles may cause excessive hose flexing at the end fittings, possibly resulting in fatigue
cracking of the hose cover and eventual failure of the hose.
2.
On 1989 and 1990 model year vehicles only, a fuel tank heat shield mounted to the rear underbody (between the tank and the exhaust system tail
pipe) may contact and damage the left rear brake tube when the rear suspension is in a full jounce position.
Either of these conditions can result in brake fluid leakage and loss of half of the diagonally split brake hydraulic system.
To eliminate the possibility of front brake hose or left rear brake tube failure, all affected vehicles must be corrected as follows:
A.
-Brake Hoses -- All involved 1988, 1989 and 1990 vehicles: Both front brake hoses must be replaced with redesigned hoses that provide a
modified routing configuration.
B.
-Fuel Tank Heat Shield -- 1989 and 1990 model year vehicles only: The fuel tank heat shield must be modified to prevent possible contact
between the shield and the left rear brake tube.
Details of this service action are explained in the following sections.
Note:
As an additional service aid, a videotape demonstrating the service procedure is included in the March, 1991 Master Tech and VideoTec programs.
Vehicle List
Each dealer to whom involved cars were invoiced (or the current dealer at the same location) will receive a vehicle list with this letter arranged in
Vehicle Identification Number (VIN) sequence. Owners known to Chrysler are also listed. The lists are for dealer reference in arranging for service of
involved cars as needed.
Each dealer without a Vehicle List will receive an information copy of this letter by Compak Mail for use in performing the service on involved cars
upon request.
Parts
Important:
For this recall, parts will be shipped and billed to involved dealers in accordance with the newly announced Recall Parts Pricing policy.
A partial quantity of front brake hose parts packages will be distributed initially to all involved dealers. As this quantity will be only a portion of the
total parts requirement, dealers must order additional front brake hose packages as needed to support customer demand.
Each dealer to whom vehicles in the recall were invoiced (or the current dealer at the same location) will receive enough Brake Hose Parts Packages, PN
C3940401, to service 25% of those vehicles.
Each package contains (1) right hand and (1) left hand front brake hose assembly, (4) washers and (2) spring clips, to service one car. Also included in
each package is an instruction summary for convenient reference by the servicing technician.
Additional brake hose packages may be ordered from Parts Depots if required.
No parts are being provided for the heat shield/brake tube portion of the recall. In the event that a tube shows signs of fluid leakage due to contact with
the heat shield, the tube should be replaced following normal brake tube replacement service procedures.
