Brake Bosster Pump

Just took bus out for fuel and upon returning the brake booster pump is running continuously. Replace O-rings in the past to stop a leak. Not sure what to do have to be somewhere tomorrow in the bus.

lift up on your brake pedal see if it stops. the brake switch may need an adjustment or replaced.

I know on my bus 1992 International if I don't do a brake check before I turn on the key and start it without doing the brake check the emergency brake motor will continue to run until I shut it off and restart it with a brake check before I turn the key on

I believe the circuit that activates the booster pump on IH vehicles is turned on when the switch is on, but pressure is low. I'd start with the simple stuff - fluid level in the steering pump (which also supplies the brake booster), lines from the pump and lastly the pump itself. Also check the pressure sensor and it's associate circuit.

Remember these systems are designed to be "Fail-Safe", which does *NOT* mean fail-proof! Consider this - if something fails, what's the safest possible thing? Well, I'd want that pump to run so I can steer and stop that bus, no matter what else. (Of course it's still possible to lose power assist, but it's at least engineered to try to provide that if everything is otherwise in order).
