Cannot find a brake fluid reservoir in 1980 Brave

[Varyk]

1980 Winnebago brave. I believe I located the brake master cylinder, in the pictures, but my owners manual say the brake fluid reservoir is ahead and above the front left wheel and I don't see any reservoir there. I don't see any tubes leading out of the top of the master cylinder either to follow to a reservoir.

Is it possible I just have the master cylinder and I have to add the fluid that way?

As I mentioned in your other post, the last picture you took is actually what you are looking for. Pull the wire on top towards you and the cap will come off. try not to get any rust into the fluid.

Pull the bail towards you and lift the oval shaped metal cap off.
