How do you add brake fluid to the reserve

I am going to bleed out a bit of brake fluid so as to refresh the old fluid in the reserve - my van is 1998 so 10 years old now. The problem is I have yet to figure out how are you supose to add new brake fluid since the cap on the reserve is shoe horned back up under the cowl or under the wipers.

I am thinking of buying a few feet of hose to attach to my funnel end and maybe I can snake it back in there if I am even lucky enough to be able to reach back there to remove the darn cap.

Any other ideas on how to add brake fluid?

The power steering reserve is a piece of cake compared to the brake fluid on the 3.4L in the Ventures.

you really kinda already answerd the question, I am thinking of buying a few feet of hose to attach to my funnel end and maybe I can snake it back in there if I am even lucky enough to be able to reach back there to remove the darn cap.
