[s-cars] Rear brake line removal help needed

[Dave Ellis]

Thanks for the help!  It was pretty straight forward once I knew what I 
was looking at and got thirteen years of gunge off the mount point.

I managed to get one off but the other refused to budge, and I gave up 
on it before I totally rounded the soft brass nut holding it on.  On 
that one I ended up rotating the old caliper to disconnect it from the 
flexible line, and installed it in reverse.

Since the flexible lines look pretty worn out, I plan on getting some 
braided steel ones and working out the stuck nut problem then (and 
closer to home).

Thanks!
-Dave
