wont roll
Ready to get moving on my project again. It was towed to my house on a flat bed and had to be slid off the truck with soap! I`v rolled it under the carport with a roll around jack. I got the engine running and then the holidays hit so it sat for the last couple months. When the engine is running I can let out the clutch and nothing happens like maybe the throw out is stuck. The rear wheels wont move at all, I`m thinking the parking brake is stuck. I`m thinking about removing the u-joints from the half shafts to see if the brakes are whats holding it. I dont want to take apart stuff I`m not ready to work on, so I thought I would ask for ideas. I cant drag it around to free it up cause I wouldnt be able to get it back under the carport. Any ideas? The shifter feels like it is shifting properly.

You have a floor jack so jack it up in the back, put it in neutral and you should be able to feel which side if any is stuck. But really, pulling the rear wheels and rotors is no big deal, if a parking brake is stuck it may be a chore getting that one off. Make sure your ebrake cable is actually released, it too may be stuck holding the brakes on. Take a mallet (not hammer) after you remove the wheels and tap around the edges of the drum while rocking the rotor/drum back and forth till it slips off. Good luck

I would try taking the pads out of the calipers first. I had a Camaro that wouldn't roll after sitting for six months and the problem was rusty rotors. Taking the calipers off allowed it to roll. By the way, these were on the front so there was no parking brake involved.

Thanks man, I already have it on floor jacks with the wheels off. Neither side will budge even if I put the tire on for leverage. I have no idea how the emergency brake works so I`m assuming thats my problem. How do you access the emergency brake? Do you have to remove the hub? I`m probably gonna take out one of the half shafts to make sure that is whats holding it.
Good Luck!

no roll
is the drive line tight ,meaning o play in wheel motion,or a little play but won't turn? A little play could be trans stuck in 2 gears.If this is the case a shifter adjustment may solve the problem.

If you do remove a half shaft, be aware that this piece also serves as the upper link of the rear suspension. If you place the car back on it's wheels without the shaft in place, expect to permanently damage the trailing arm.

Thanks for the heads up! I would not have known this and probably done just what I shouldnt have.

No nothing spins, which makes me think the the tranny shaft is rusted and holding the throw out bearing. It doesnt even make a noise like something in the tranny is spining though??? When I got the car the keys were lost and the tranny was locked in reverse so I thought it was locked up. Someone on here told me that vettes trannys lock in reverse when the key is in lock position. When I finally switched out the key switch and turned the ignition on the shifter moved freely and shifts through all the gears just fine.

I'd pull the drive shaft and see what's locked up and what isn't.. it would sure be nice if the tranny was locked in 2 gears or something, making the input shaft spin freely and locking up the rest of the drive train.

simple troubleshooting.
remove driveshaft...
this will determine of problem is behind or in front of driveshaft
if tranny tailshaft won't spin then trans is locked in 2 gears ( happens alot with a muncie and mis-adjusted shifter linkage).
if tranny tailshaft does spin, then problem is in rear end.
remove half shafts now to find out if rear end is locked up or wheels..

Wouldn't a locked up trashed diff feel about the same as a locked up Ebrake? Either one would keep it from moving. If the diff and ebrake are OK then it would move back and forth however far the play will allow, but that only proves the ebarake and hub are not frozen, not that the diff is in good shape, it still needs d/c to prove each item IMHO.
