[DeTomaso] Stock brake calibers & other musings

[Larry - Ohio Time Corp]

Hi Will,

The only brake lines that will not rust are stainless steel. Most
replacements have a very thin cote of Zink on them, but they to will rust to
if nicked or scratched at all.

One other interesting noteŠ

I was repairing a leaky brake line near the master cylinder one evening.
I pulled the hard line away from the master so I could attach a flaring
tool.  I pulled a little too hard and the whole line snapped from under the
car.  I wasn't pulling like a gorilla.  It certainly shouldn't have snapped.
There was a lot of rust on the line where it snapped.  I didn't think brake
lines rusted.  Maybe I'm remember it incorrectly.  I spent the next 2 hours
under the car replacing the line from the master to the rear tee.

It could have just as easily broken while I was on the road.  That would
have been fun.

But echoing your comments, my brakes were fantastic once they were working
properly.  And I didn't even rebuild the calipers.
