My '83 240D has the original 27 year old back brake lines, I think. An indy
who replaced the back calipers for my wife was supposed to have replaced
them, but if he did, he got the connections to the metal brake lines the
tightest I've ever seen. I've treated these upper connections with
Kroil, WD-40, Rusteater, Blaster, the ATF 50-50 mix, and several others to
no avail. I've put cheater bars on the 11 and 14 mm tubing wrenches and put
as much force as I dared, without success.
Can anyone suggest a different method to try? I've never heated a line full
of brake fluid with a propane torch before, but that seems like one of the
remaining things to try if it can be done safely.
The brake lines connections to the fairly new calipers came loose easily.
It's the top ones that won't break loose.
Thanks,
Gerry
'83 300D and 240D
