Operation
Before driving the vehicle, secure all loose items in the bus so that they will not fly forward during a full brake application. Check that the brake system warning light is off after releasing the hand brake. If the warning light does not go off, correct the problem before continuing operation of the vehicle.
During normal braking stops, depress the brake pedal until braking action slows down the vehicle. Increase or decrease the pressure on the pedal so that the vehicle comes to a smooth, safe stop. Apply the hand parking brake if the vehicle is to be parked.
Important: Make sure that the brake fluid in the main cylinder reservoirs is up to the bottom of the fill-neck. See Fig.. Use only DOT 3 brake fluid in the Bosch hydraulic pin slide brake system.
Due to the mounting angle of the main cylinder on some vehicles, it is not possible to fill the back reservoir up to the bottom of the fill-neck. For these vehicles, fill only the front main cylinder reservoir up to the bottom of the fill-neck. See Fig. for an example of the alternate mounting angle.

Open caps and check fluid level.
