Emergency Brake not holding?

Ok.........I did a re-think on this question.

The double bleeders on the rears (which seemed kinda strange compared to the fronts, and considering the minipad), heck who knows.

The emer brake.......hmm.......thats the purpose of it. Should be 100% mechanical, so I may just need to adjust the cable some more inwards. (it moves fine on the caliper, in-out...etc)

Your rig seems to be non-stock from your description; each single-piston rear caliper has one (1.0) hydraulic bleeder valve. However, I had problems with one guys car- no fluid flow from one rear bleeder. I removed the bleeder needle and DRILLED out the passages which were solidly clogged with dirt/rust/varnish. Second, these are sliding calipers (as-stock) and if the units aren't sliding under cable pulls, you need to free them up & put a spot of axle grease on the slide paths. Finally, theres a setscrew adjustment in the caliper side behind the moving pad, that sets slide clearance; in rare csaes, this may need adjustment.

Jack......Know what, my mistake, 1 bleeder in rear. So its a totally mechanical deal. Pull arm in car, pulls cable(s), pushes "plunger" in rear of caliper?

If thats the case I may just need to adjust it more? (think they are two 18mm's on either side of mount bracket)

BTW....Thanks Jack...... Hey, no vacation when I need an answer :-)

Yeah, Kaama, its mechanical- what happens is, you pull the cable & the whole caliper moves against the big horse-shoe shaped steel loop surrounding the rear caliper. The e-brake pad is actually the non-moving one. The brake is self-adjusting if you put the car in reverse and hit the e- brakes in that direction a few times- somehow it takes up the slack in the cable. And this only happens if the slot in the piston is turned 45 degrees to the vertical, by the way; there's a clevis inside the caliper body that actuates in that position. If the slot is vertical, the clevis releases & no self-adjusting occurs.Try this before messing with the adjusters.

Well Jack is close but the slot has to be vertical to adjust out the wear in the pads and lock the inner and outer pistons together. Rotating 45 degrees releases the pistons and defeats the emergency brake. It is only drum brakes that self adjust by applying while backing. The Pantera dsics will self adjust any time they are applied regardless of direction or even when standing still as long as the slot is vertical or horizontal.
