Do I have Dual Circuit Brakes?

[Jinx]

Got my truck today! I was giving it an inspection before driving it home. While under the truck inspecting for leaks, I noticed my truck has 2 air tanks. There is no brake light on the instrument cluster and no electrical switch on the e-brake, but there is definitely two tanks. Plus there's a decal on the glove box pictured below.

As for leaks, I saw a wet area around the transfer case and another by the oil pan, but nothing puddling under the truck.

By the Way, how in the world to I check the brake fluid level? I opened the panel on the floor expecting to see a cap on a master brake cylinder similar to a car.

It's an older truck, but shows it had a rebuild in 1991. It also has the 465-D Continental engine and the non-whistler turbo.

It does not have dual master cylinders. It has the latest version master cylinder, that's all. All deuces have 2 air tanks. Read the TMs for the BFS level inspection procedure. You need to take a vent line off and then take the cap off. It don't have a "cap like a car", because it's a military truck!

What DH said. You would need to see dual air packs, not tanks.

And congrats on getting your truck! Safety should be the #1 priority in our hobby. I'm glad to see questions at least asked here, rather than your truck stuck in the side of a Ford Escort in about two weeks on I-5.

its not a car, it says it has a new upgraded master cylinder so it has a new upgraded master cylinder, it has 2 air tanks they all have 2 air tanks, it is air over hydrolic,a simple system but U need to get the TM's also and read, Also U need to do ALOT of reading !! start your serching on all things deuce and u will understand alot more, All the best remember this is a tactical truck , it drives slow and is meant to go slow, it needs ALOT of TLC tighten everything, if it gets away from U U will never bring it back, so learn it all read read read...I mean this with all sincerity, all the best!!!!!!!!...Randy

Be sure to clean around it good, real easy for dirt to fall in. Wayne

Got it. Dual tanks are standard. I was under the impression that single tanks were standard on single circuit trucks.

Thanks for the brake advice papercu. I blasted it with brake cleaner first.

I scoured the TM's recommended here, both 9-2320-361-10 & 9-2320-361-20, but there is surprisingly little information about how to check the brake fluid.

Take the top off of the master cylinder, fill it up w/dot 5, close cap. That is pretty much it unless you need to bleed your brakes.
