I've been chipping away at the 'ol '73 when time permits.
Discovered the MC was leaking. The hard line that leads to the rear brakes was, cold welded/rusted frozen aint budgin' on the verge of breaking, to the nut.
I did the pb blaster thing for a few days. Kept trying to work the line free with minimal twisting. I then found out about the acetone/atf concoction. Tried that for a few days. Kept everything wet the best I could but being a liquid doesn't allow much to sit there. I left things alone for probably two weeks. Went out there with a pair of pliers to hold the line and a 9/16 line wrench for the nut. Held the line firmly while twisting the nut back and forth and voila, she broke loose.
I cried but nobody saw. The whole ordeal spanned prolly three weeks but I was amazed I was able to save the brake line.
