This report documents the findings of an incremental cost, weight, and leadtime analysis developed from process cost and weight teardown of heavy truck antilock braking system (ABS) hardware from three manufacturers - Rockwell/WABCO, Midland-Grau and Bendix. Both truck tractor and trailer ABS configurations were studied including failure warning systems and several types of ABS tractor/trailer connectors. The scope of this study was confined to Class 7 and 8 trucks and tractor/trailers, which represent 72.4% of the total vehicles under consideration. A baseline tractor/trailer combination, an "18-wheeler" Navistar tractor pulling a Great Dane trailer, was used to determine cost and weight estimates of the three different ABS manufacturers' hardware and ABS configurations when fully installed on the vehicle. A supplementary analysis of Class 7 single unit trucks using Rockwell/WABCO hardware provided estimates for incremental cost and weight impacts for this class of vehicle. The significant findings of this study are: 1) Tractor/trailer ABS configurations examined in this study should result in price and weight increases no greater than $1700 and 100 pounds per vehicle combination; 2) Single unit heavy truck ABS should result in price increases of $900 or less per vehicle; and 3) The proposed effective dates for ABS installation for each vehicle type should permit adequate leadtime for implementation of heavy truck ABSs as standard equipment.

  • Supplemental Notes:
    • Detailed impact estimates developed in this report are based on ABS teardown data supplied in Contract DTNH22-94-R-02003, "Micro Cost and Weight Estimates for Six ABS Designs/Configurations and Tractor/Trailer Model Applications".
