I have a 1992 International DT360 with hydraulic brakes. We have forever tried to get this light to quit coming on at random, this light I speak of is the "Brake Press" light!!! The light and beeper can be reset if you shut the bus off then turn it back on, but comes back on when it feels like it. We have performed the following repairs with no luck:
1. Replaced all power steering hoses (dealer recommended) 2. Replaced power steering pump (dealer recommended) 3. Replaced master cylinder (shot in the dark) 4. Replaced E-motor (you never know) 5. Replaced brake lines to the master cylinder (leaking)
Brakes and calipers are like new all the way around. I hope someone can help, this has been a thorn in my side for a long time.
