Brakes Overheat
- 停车制动器
- 制动器冷却系统
- 行车制动盘
停车制动器通过弹簧接合和通过液压释放。
虽然停车制动器应用为机械式,从停车制动器释放系统排出空气也是重要的。 在发动机运行的同时,驱动停车制动器开关五次。 此动作可排出管路中的空气。 以 1 分钟的间隔驱动制动器。 停车制动器将在空气排净后释放。
应通过 Cat 电子技师核实制动系统压力。

注: 797F 卡车没有配备下述优先阀。
当转向系统的需求得到满足时,优先阀将油从转向泵引至制动器冷却马达。 制动器冷却马达驱动制动器冷却泵。 制动器冷却泵将油送往以下部件。
- 前制动器油冷却器的滤网
- 后制动器油冷却器的滤网
- 后制动器油冷却器
- 前制动器油冷却器
- 后轮行车和停车制动器
- 前轮行车和停车制动器
来自举倾阀的机油流过举倾和制动冷却的机油滤清器。 机油随后流至前制动器油冷却器和后制动器油冷却器。 此油流为制动器提供了额外冷却油。

行车制动器和减速器采用液压接合和弹簧分离形式。 当行车制动器或减速器接合时,油通过松紧调整器送往行车制动器和减速器油道。
检查钢板厚度,有无表面刻痕,有无放射状沟槽,以及有无弯曲。
