I had the same problem. If you have not already noticed there are two set screws on each side of both clalipers. One is accesable through a hole in the rear trailing arm (after a small cover plug in the caliper is removed , this plug may or may not be present depending on the PO) and the other is in plane view on the outside. Both requre an alen rench to adjust with the outer having a locking nut. The one on the back side has to be tightened to the point that it almost makes the inside break pad rub. This will provide the E-break lever and outer piston somthing to push against. If the inner set screw is to loose then you will have week e-break performance. Since you have no e-break sounds like a promlem with the outer set. The e-break lever acts as a shuttle against a worm type gear; so when the e-break lever is actuated it should spin the worm gear thus raming it forward displacing the outer cylinder against the disk which pushes against the inner cylinder which should push against the inner set screw. There is suposed to be an automatic rachiting forward of the worm gear so as the pad wares the worm gear shaft follows the piston and always has the right throw to properly engage the outer piston. This does not always happen, as was my case, if the worm gear/ set screw combination is not damaged then it is a simple matter or tighting the set screw while holding the e-break lever beyond its full actuated position so a to disengage it from the worm gear. this will allow you to adjust the set screw to the point where the worm gear is in contact with the break cylinder piston so when you release the e-break lever it will retract to worm gear off the cylinder. You will then need to fine tune the set screw so that the the worm gear has the proper range of motion ie. no e-break/no pressure applied to outer cylinder, with e-break lots of pressure. A side note check your rear rotors they may be warped from to much use with non adjusted e-break. Mine were so bad that once I got the e-brake adjusted I had to replace the rotors because I could have e-break and rubbing rotors or no e-break and rotors that cleared. Also I think that to outer set scew was a lefty tighty/righty loosey deal, had me going for a while.....
