Customer Satisfaction 00024 - Front Brake Hose Abrasion

On certain 1999-2000 Chevrolet Silverado and GMC Sierra 1/2 ton pickup trucks, failure to follow the service procedure set forth in the Service Manual for removal of the front brake caliper can result in movement of the front brake hose relative to its knuckle mounting bracket. If this movement results in increased length between the bracket and the banjo fitting that attaches to the brake caliper, it is possible for the brake hose to come in contact with the wheel rim. This contact with the wheel rim could, in time, cause the brake hose to become worn to the point that brake fluid leakage could occur. If this occurred, loss of front brakes is possible.

Dealers are to attach a notice label to the front brake hoses stating that the calipers must be supported when removed.

Involved are certain 1999-2000 Chevrolet Silverado and GMC Sierra 1/2 ton pickup trucks built within the following VIN breakpoints:

Important: Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada only) or DSC Screen 445 (IPC only) prior to beginning campaign repairs. [Not all vehicles within the above breakpoints may be involved.]

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.
