brakes dragging

Have you changed the pads recently? If so, the pistons have been pushed further back into the bores where they will often pick up dirt and varnish which will cause sticking.

Might be time to pull the calipers apart and rebuild them.

Could be a collapsed brakehose, so it won't release the pressure.

Your probably right because when I open the bleeder they stay tight, so it must be sticky bores. Do any vendors have trade in or rebuild programs. I have 3 sets of rear calipers but I don't want to BUILD them myself. Wilkinson has the kits $19.95 enough for both sides. http://www.panterapartsusa.com...l.cgi?prod_id=01001C He had the cylinders complete for $385 each{ouch} all of a sudden rebuilding them myself ain't a bad idea after all.

Bill,

Read all about AsaJay's caliper rebuild in the Jan 2009 POCA newsletter:

And watch his caliper rebuild videos linked here:

Larry Stock at PPC Carson City does have rebuilts in stock, but there are a couple of other things you can check before ripping the calipers off & shipping them.
First, remove the wheels and get right up close, then have a friend step on the brakes hard while you WATCH the piston move and retract. If one does not, that one is sticking in its bore for some reason. I found one neglected Pantera that would not leak brake fluid when a rear bleed needle was REMOVED! I had to drill out the orifice below the needle seat which was full of corrosion & varnish.
A second thing is to disconnect the e-brake cable on each rear caliper and repeat the test. Cables have been known to freeze in their jackets from wear, rust or even badly applied undercoating. The e-brake's self-adjusting internal feature automatically tightens up the adjustment when you pull the lever. If the cables are sticky, this can hold the brake permanently 'on'. A loose or mangled under-car bellcrank (just in front of the engine, below the rear firewall) can also stick rear calipers.
But mainly, water in old brake fluid forms rust and varnish that will stick pistons front or rear, and which must be scrubbed off manually after disassembly- a messy, tedious but not impossible weekend chore. If the rears are sticky, I'd look really closely at the 8 front pistons, too.

Thanks for the links Garth. I ordered the kits from Wilkinson, probably a week before they get here. I'm soaking my best looking set now. Bill 1362
