All four wheels accept the left rear have seized calipers (wheels will roll only with engine power). Is this a brake line issue where the link between the hard line and the caliper is collapsing on itself?
Thank You,

I would suspect siezed caplipers ? whats gives you the indication a brake line is colapsed ?

...WD-40 solved My problem!...
...Don't get it on the pads or rotor, though!...

Not likely.
VERY likely you have frozen caliper pistons. You need front and rear rebuild kits, time and patience. Hardest part to rebuild frozen calipers will be getting the stuck pistons out.
Compressed air with the calipers sitting on your workbench will usually do the job. Drain them well before blasting them apart. Messy. I like wooden blocks, of varying thickness and size, placed where the pads usually are, and a stout C-clamp. Usually a good air blast will dislodge one or two, but not all of them at once. By clamping the loosened ones with the C-clamp, and then getting the others to pop loose, you'll get them all free. Good cleaning, scotch brite for varnish buildup, brake assembly lube, new stainless steel brake lines (a must for about $125) and you may be in business. But I suspect the MC may also need attention.

Had read an article somewhere about a pantera that had sat a while like mine and that the brake hose had weakened and it collapses on itself causing a vacuum.
Thanks for all the great suggestions. Is it advisable to put these cars up on floor stands and if so, where is the best place on the chassis? I have a four post lift and could lower the car onto the stands and work on all four corners at once.
I use 2 stands on either side of the rear cross-member (at the rear of the ZF) and 1 on each side near the front of the doors on the square "rails" underneath.
Hi Khan,
Congrats on your Pantera purchase!
Husker has the right support points. On the rear cross member, I use a steel plate that spans the length of the cross member (channel or square tubing works). If you want to lift both the front and rear wheels on one side of the car (at the same time), place the jack near the rear of the door (on the sub frame). This will raise both front and rear wheels at the same time. There is a pinch weld that will require the use of two metal plates (one on each side of the flange). The plates keep the jack from bending the pinch weld and collapsing the sub frame.
As for the hydraulics, don't take any chances. Rebuild everything. Do the brake master, clutch master, clutch slave cyl, and brake calipers. Flush the hydraulic lines. Add the stainless flex lines. Closely inspect all of the hydraulic tubing, especially under the car where they run down the center. Look for any signs of chafing or pitting especially where they are held by those fold over straps.
