Anyone know what this is called? (Truck part)

 

I've got an old 1987 Mitsubishi truck. This is pissing out air so need to replace it. 

It was located beneath the cab directly under the brake pedal, which attaches to it. 

Any info greatly appreciated!

Power steering pump?

Hydraulic pump?

Muffler bearing. 

I didn't even break any socket wrenches when removing it!

Its not anything to do with power steering. 

Its some kind of pneumatic unit that is connected to the braking system. Just not sure what it's called

I'm actually amazed no one has suggested it's a tyre, considering I said it's leaking air

They're air hose fittings rather than hydraulic ones. 

Yea I thought a brake booster of some sort too. Might just take it to a mechanic and see if they can give me the proper name
