Service brake system
The service brake system, also called foot brake, is used for frequent speed control during general
traveling. The service brake system of this loader is composed of caliper disc brake, gas
pushedoilbooster pump and pedal. Front/rear wheel braking torque conversion ratio is 1:1. The front
and rear wheel brakes are exchangeable and equipped with front and rear booster pumps respectively.
The whole service brake system is characterized by stable braking, safety, reliability, simple structure,
convenient maintenance, easy sewage disposal and good recovery performance.
