different brake line materials what do you use?

AND NOW YET ANOTHER annoying story from the old days. Sometime in the mid-late 70's a then friend bought a ?? Ford Ranchero, about a 67 I think. SINGLE master cylinder. he lived on the "Baldy mountain road" which came down from his place around a steep decending hill and corner, to a straight down an impressive hill and then leveled to a pretty straight sometimes "humpy" county road, 35mph, to a "dead end TEE" at Boyer. Across the road at the "tee" was an fence and narrow bumpy access road alongside some power lines

Anyhow he came blasting down the hill one day, (speeding) roared up to the stop sign at the "tee" and mashed the brakes---"sorta like steppin on a plumb" says C.W. McCall.

.............And roared right across the street and through the fence and down the acess road, where the 4 speed and parking brake eventually got 'er stopped.

The trouble? LOLOL. He had just bought this thing only had it for a couple weeks. When he got it home he found out that the brake tube had been damaged near the crossmember, and SOMEONE HAD SPLICED IT with fuel hose and clamps!!!!

that dumb- assery is ok for a laugh as long as no one was hurt LOL!
