I’ve always simply loosened the cable, then pulled the lever up two clicks, and tightened the cable. Then I find the car is firmly held by two or three clicks of the lever.

Brad, do you then check to make sure the ebrake is not dragging when disengaged?

Right? It should be that easy, Had them working as they should, In first they held, But only once. That is why
i am thinking it is the calipers. They should hold and release.

Absolutely. I also find the brake handle has a certain feel to it when the brakes are released or engaged, regardless of the clicks.

Weird - not retracting. Spring assembled wrong perhaps. I've never really had a rear caliper fail, I've just cursed a lot rebuilding them.

I pulled the new caliper off the drivers side. Acuated the e brake lever by hand, no action on the piston, Has to be assembled incorrectly. Not right

Maybe someone broke the piece inside the piston where the rod screws in.

Apparently what tima01887 has got is going around, as I had the exact same problem yesterday with a rear caliper that I had just rebuilt a few weeks ago. Symptoms were the same: hydraulic brake worked fine, but no emergency brake after one or two uses. The cause was that the circlip that holds the retainer plate inside the piston had popped out of its groove, for unknown reasons. Corrected this last night and I'm back in business, with the rear wheels grabbing solidly after 2-3 clicks on the handbrake lever.

How would that happen and who would do such a thing?
