This SAE Recommended Practice establishes methods to determine grade parking performance with respect to: a. Ability of the parking brake system to lock the braked wheels; b. The vehicle holding or sliding on the grade, fully loaded or unloaded; c. Applied manual effort; d. Unburnished or burnished brake lining friction conditions; e. Down and up grade directions. This document establishes a uniform procedure for determining the parking performance on a grade by the parking brake systems of new vehicles over 4536 kg (10 000 lb) gross vehicle weight rating (GVWR) intended for roadway use.
