本SAE推荐规程建立了一个统一的实验室程序，用于通过车辆试验和运行条件的惯性测功机模拟来评估汽车制动器和制动鼓的性能和磨损。本规范适用于液压、空气或电动制动器。对于电动制动器，如果程序或数据和曲线表中有规定，则用“安培”值代替“管路压力”。该程序包括以下测试:1。扭矩输出和减速（各种速度和制动输入）。2.衬里寿命评估（磨损试验）。3.制动特性（衰减和恢复试验、噪音、颤振、抓地性）。4.滚筒评估（磨损、热检查、划线）。

This SAE Recommended Practice establishes a uniform laboratory procedure for evaluating performance and wear of automotive brakes and brake drums by an inertial dynamometer simulation of vehicle test and operating conditions. The code is applicable to hydraulic, air, or electrically actuated brakes. For electric brakes, "ampere" values are substituted for "line pressure" where specified in the procedure or on data and curve sheets. The procedure includes the following tests: 1. Torque output and deceleration (various speeds and brake input). 2. Evaluation of lining life (wear tests). 3. Brake characteristics (fade and recovery tests, noise, chatter, grabbiness). 4. Drum evaluation (wear, heat checking, scoring).
