I recall on my 78 that same issue. I opened the driver's side panel and replaced the relay that controls the brake lights. Test light should identify the bad relay. There are several located in that area. Good luck.

Check the fuse in the outside left front compartment. If its good you may have a bad brake light switch. It will be an air activated switch. No chains or hoses running to it. At least that is way it was on our 83.

Pictures help when your trying to get us to help identify a part.

My 78 did not have that switch peddle or the chain. I still would try the relays on that side of the coach behind the panel that swings out. It's been about 20 years, but that is where I found my problem. Then again, 78 to 80 may have some differences.
Good Luck!

That is a disconnect for the cruise control. Switch is normally closed. When you step on the brake switch opens and drops the cruise.

Good Luck!

Checking the fuse first is much easier than going through all the relays. If the fuse is good then do the tougher stuff. Sometimes the simple stuff is broken.

Other thing is, our 83 had the relay for the brake lights in the left rear overhead compartment and not up front.

On mine the relay clicks above the driver when I press the pedal. Check that first.i had to replace my brake light switches in the foot valve . There is a access cover under the carpet next to the steering column and there was two switches wired together screwed into the foot valve. I don't know why there is two maybe redundant on school busses? I got them from the local truck supply. A little tight getting them out , I had to cut a wrench to fit.
