This brake hose transmits hydraulic pressure from the master cylinder to the wheel brake actuator on the host machine. It is a flexible section of the brake circuit, accommodating relative movement between the chassis and the axle assembly. A ruptured or internally collapsed hose causes a loss of braking force or a dragging brake, respectively. This component is manufactured to the original hose length and fitting geometry so that it routes without kinking and seals against the hard-line connections.
