Just changed rear drums, pads and parking brakes. Got it all back together and it seemed to work ok in the driveway. Went down the road and the rears are stuck on. Took them apart and checked and tried again and still the same. Are my calipers messed up? The second time I took them apart I put a block in and hit the brakes to see if the pistons would come out. one did but the second one on both sides took a HARD push on the pedal to make them go. Did i mess up something pushing them in?

Got 12 v at the plug deal. Electromagnet seems to be working, tried to help it spin and it grabbed the screwdriver I was holding and flung it , can I check the operation of the clutch somehow? How hard to change it.

Got a question anOut my AC. Put some gauges on and the pressure seems ok. The problem is the clutch engages but turns slowly. Squirted it out with electric cleaner but didnt help. Do these go bad? It doesn't "snap" into engage, it just slowly starts turning. Could something else be stopping It?
