Do you mean the brakes are frozen in the 'on' position? If not, you should be able to put the car in nuetral and roll it in and out, shouldn't you. You could put chocks in front and behind the wheels to keep it from rolling away while on the driveway.
Would a 'bug bomb' kill the black widows and other critters before you worked on it? Obviously, you'd want to wait until the car is outside to use one of those.;o)
Apparently the brakes are actually stuck to the wheels. From what I understand, this is a common problem for cars that sit outside too long...the pads either stick or something actually rusts to the wheels.
Supposedly, I can spray a substance called "PB Blaster" on the brakes, let it sit, then bang 'em with a mallet. It's not likely we'll be keeping these brakes...more likely the whole system will have to be overhauled...so we just need to bang 'em loose so we can roll it around.
