Being it’s a former fire truck it could be very low miles with little wear and the brake drums and shoes
The dull paint tells me it hasn’t been in the fire service for some time and has been setting out, setting out for periods of time is hard on soft parts, wheel cylinders, master cylinders, brake booster diaphragm's, carburetor gaskets and seals
Figuring out which brake system it has is as simple as climbing up into the cab and looking at the instrument panel, if air brakes there will be a air guage somewhere, for juice brakes there may be a vacuum gauge or no gauge at all.
If juice brakes step on the brake pedal, if the pedal goes all the way to the floor you’ve got a little brake work to do
Most of those front mount fire pumps are driven from the end of the engines crankshaft will some type of shifting mechanism to engage and disengage the pump

A fire pumps flow is variable depending on pump speed and hose sizes
500 gpm means the pump is capable of flowing up to 500 gpm at 150 psi at max rpm, but at idle it may only flow a few gpm through a garden hose at 20-30 psi

I see that makes sense. I talked to a couple companies about rebuilds for the Clark 285v and I was told that parts were not being made anymore. While I could find some, the future availability worries me. Does anyone have other direct bolt up transmission suggestions?

Look under the truck to see if there is a pto unit on the side of the transmission to drive the fire pump or any other device on the truck
If it does have a pto and you swap to another brand or model of transmission you’ll have to also get another pto unit for that transmission
The pto’s will no swap from one brand of transmission to another and most often not even between different models of the same brand
Having to replace a pto unit can add $500 to $1000+ to the cost of a transmission swap

A couple of Clark 285V transmissions (for Fords) have hit FBM in the last year in the PNW, but "285V" is only the Series, isn't the complete model number, and isn't enough to know if it will work well as a replacement, as the letter/numbers after that specify different gearing options etc. It might bolt in but have gearing suitable for a diesel, etc.
I have a 282V36 that has no synchros left on 3rd and is also fairly noisy, with clean oil, and I would love to know if a 285Vxx would bolt in place of it, but generic questioning hasn't yielded any definitive responses yet. I'm not really interested in taking it apart and replacing those synchro parts (even though ~$400 would buy them), as that's a can-o-worms I don't need at this stage of life, BTDT. I double clutch into 3rd from both directions, which for the few miles I put on it is acceptable.
