制动器冷却泵是一个三段式泵，位于液压油箱内。 制动器冷却泵段由制动器冷却活塞马达驱动。
驱动活塞马达的活塞泵由制动器 ECM 控制。 制动器 ECM 分析有关制动器冷却泵段转速的三个因素。 参考系统操作, "电子控制模块（制动器）"了解有关控制逻辑的更多信息。
前制动器冷却泵段 (3) 将机油通过滤网输送至前制动器机油冷却器。 后制动器冷却泵段 (4) 将冷却油通过滤网输送至后制动器机油冷却器。 来自制动器冷却泵的机油与来自举倾和制动器冷却齿轮泵的机油汇合在一起。 该油流至盘式制动器。 机油冷却制动器后流回到液压油箱。
至机油冷却器的两条出口管路中都有一个安全阀。 机油冷却器安全阀位于液压油箱内。 如果出口管路中的压力升高至安全压力，安全阀将打开，机油将流入液压油箱。
