Help identifying this connection on my rear drum brakes (1 Viewer)

Hey all I’m just wonder what this hose that looks like a breather is for on my 1979 fj45 troop carrier with drum brakes all round
I am getting no movement in the back wheel cylinders, they look fine adjust fine and I have bled them and there’s no trouble getting fluid through.

Edit it’s the rear

for more context the hose on the right goes to the master the hard line on the left goes to the other back wheel unsure of highlighted one

It is a breather that vents the axle tube. Toyota utilized the hold down for the brake tube junction fitting for dual purposes, holding the fitting and venting the axle.

The "bolt" that holds the fitting in place is hollow.

kinda looks like a differential vent line

you can find a parts diagram on toyota epc (example Rear axle housing & differential for Toyota Land Cruiser FJ40LV - Genuine parts - https://toyota-usa.epc-data.com/land_cruiser/fj40lv/3668/chassis/4101/?full&picture=2) for your year that will depict the vent hose

I don’t think that has much relevance to the question but thanks

How is that hose connected to the frame at the top? I have searched forever to find a picture of that.
