Important Information about These Guidelines
Purpose
The purpose of these Brake Application Guidelines is to provide original equipment manufacturer (OEM) builders of medium and heavy duty trucks with information about which Bendix Spicer Foundation Brake products are approved by Bendix Spicer Foundation Brake for use in common vocational applications in the USA and Canada.
Use of Guidelines
These Guidelines apply to the specifi c on, on-off, and off highway vocational categories and axle applications which are listed, for vehicles operated in the USA and Canada. The categories equate to the commodity and service categories used by OEM truck builders. Within each category, Bendix Spicer Foundation Brake has approved the steer axle brake and drive axle brake applications shown in the table (subject to any applicable notes), provided that the vehicle falls within the “Defi nitions” and “Typical Vehicle Types” and meets the “General Requirements” set out for that category. Brake approval is based on gross axle weight rating (GAWR), static loaded radius of tire (SLR), air chamber size, brake adjuster length (S-cam brake only), and the brake lining material. These Guidelines do not apply to the use of Bendix Spicer Foundation Brake products in vehicles operated outside the USA and Canada, in vocational categories or axle applications other than those specifi ed herein, for duty cycles or ratings other than those listed herein, for vehicles with fi xed liftable auxiliary axles (tag or pusher) or for any off- road applications. Approval for such uses may be requested on an individual basis by submitting a Brake Application Approval Request Form to the Bendix Spicer Foundation Brake Application Engineering Department at the address below.
Brake Warranties
Bendix Spicer Foundation Brake warranties for steer axle, drive axle and trailer brakes are set out in the Bendix Spicer Foundation Brake Applications and Installations (BW7216) must either meet the requirements of these Guidelines for automatic approval or be approved by the Bendix Spicer Foundation Brake Application Engineering Department. Failure to obtain application approval or the use of Bendix Spicer Foundation Brakes or their components in non-approved applications will void the Bendix Spicer Foundation Brake warranty coverage. Modifi cation of the vehicle or brake confi guration, changes in the vocational use, or service outside the limits of these Guidelines may void the Bendix Spicer Foundation Brake warranty coverage.
