Interesting seeing the brake line on the outside of the frame, thought all Rangers ran it inside the frame…
Being in the rusty steel buckle of the rust belt, and having blown a few brake lines over the years (one bad enough that I was afraid to take it the half mile home), any time I lose a brake line on a vehicle I’m intending to keep awhile, I rip it all out and go Ni-Copp. I have enough headaches just driving old iron all the time, I don’t want to worry about my brakes.
The single reservoirs are supposed to have a float that when the fluid gets low enough they seal off the master cylinder and it’s supposed to keep brake pressure and keep air from getting into the lines. In my experience, they don’t work well and often get stuck up or down.
