OK. Mr. Goofywrench (me) has struck again.
In an attempt to examine the braking system, r & r the rear shoes, and bleed
the system on my '78 Spitfire, I've thoroughly rounded off both the bleed
screw and the brakeline nut on the back of the wheel plate.
I used my Dremmel (finally) to cut through the brake line and withdrew the
entire brake cylinder assembly and have it securely in my vise. Have tried
a little application of heat (propane torch) and LOTS of penetrating oil
(used penetrating oil from the beginning) as yet to no avail. I have three
questions:
Question Number One: When using the propane torch, do I want to try to
unscrew these buggers while it's still hot, or do I want to go thru several
cycles of heat, cooling, heat, cooling, etc (applying additonal penetrating
oil with each cooling period)?
Question B: Anticipating the debut of the dremmel, I've have a replacement
brake line from TRF, but I now see that it's NOT "pre-bent". I know there
are tools to bend them, but given my skill level is that better left to a
machine shop?
Question III: Should I just quit trying before I do (more) serious damaage
and take it to a machine shop and let them get the offending hardward out?
Thanks for any advice/cousel. Also now that I've done this I purchased
those wrenches that are semi box-end so that I hope not to repeat this on
the other side. I also closed the barn door now that my horse got out.
