As a CDL driver, this is definitely an air-brake bus, which is loads better than the Lucas-Girling nightmare. Those have a little box with a yellow label and a black toggle-switch for the parking brake just below the door arm. I can see you have the yellow air valve.
As for the squealing, good news and bad news. The good news is, it is likely a simple matter of brake pads or shoes being glazed over from overheating (shoes more likely as I don't think disc brakes were available for air systems in 1990). Not very surprising, since most route buses were extreme stop and go, and there's always a driver who brakes harder than necessary and heats the brakes up too much.
You can go two routes here. You can remove the wheels and drums and spray everything down with brake cleaner, then try sanding the shoe linings to rough them up a bit and knock off the glaze (not recommended, but if you do this, WEAR A RESPIRATOR - brake dust is no bueno for the lungs). The bad news is, the other method is to replace the brake shoes (which I recommend over resurfacing the existing ones).
You might have a professional check the system, however, just to be sure nothing is cammed-over. Not sure if this is an S-cam system, (some are, some aren't), but that is known to be a problem on such systems. I believe you'd know pretty quick with a skoolie if it were cammed over, however.
I once drove an 18-wheeler that felt like riding a jackhammer when I applied the brakes over 50. Turned out the drums were out-of round and the linings were coming apart on one side of the steer axle due to broken rivets. Now you see why I recommend replacing them.
Hope that helps!

Nice job. Is that double wall stove pipe? We made an outlet in the hole where the stop arm was attached. Wanted to recess it to avoid tearing it of .
Good luck . j

(for the tankless water heater) Yup, I it's either z-vent or b-vent, can't recall at the moment. Goes up 18" before the 90° bend to the outside. That's the minimum distance before a turn according to the manual. I'll take some outside pics today as well.

It REALLY DOES help...
BTW, you might also check to make sure none of the drums are cracked, that can cause all kinds of issues with irregularly worn or damaged brake linings. Could just be heavy brake dust deposits stuck between the linings and the drums, but for as much work as it is to pull the wheels and drums... You pays/saves your money and you takes your chances...

First you need to decide which is cheaper, brakes or earplugs.

So I’m kinda stuck on a few things and any advice is appreciated.
1: wiring in a flasher relay to market lights. The marker lights are run from a toggle switch. I have some of these Bosch relays I salvaged from my wire area (pics 1 & w). I’m pretty sure for the marker lights I can splice into the line and run the relay from another switch?
2. Warning lights on dash: how the heck do I figure out if they actually work?
3. Temp gauge: I saw what looked like a temperature gauge coming out of the side of the transmission pan. Not sure if mine is working or not? Is that possibly what that is? (AT545).

I believe that is the backup light switch and buzzer.
Do you want your marker lights to flash or just control from another location?
Warning lights on inst panel another different kettle of fish requiring individual tests.

I would like to make the clearance lights flash all at once. Right now, my hazards are just the blinkers. You think this Bosch relay would work?
Yeah, I figured the warning lights would be a p.i.a.
