Very stubborn Brake lines
 

i seem to have quite a problem..

i just completed the rear disc conversion on my 94 ex and my new 4040 prop valve is on the way but i can't get the old lines (6) of them off. i just rounded the heads with a flare wrench.

i have some PB blaster and heard that heat is the next best option but my question is won't the heat mess something up? i have one of those little blue propane ones, is it safe to heat up the old prop valve fittings and remove them?

Thanks for the help

Don't use heat on brake system components. Try the PB Blaster and some big vise grips, clamped by a gorilla.
