I'm doing the rebuild, I'm almost done but I can't thread it back on. The spring pushes on it too hard I guess. What do I do? I didn't remove the bolt on the back of the caliper that holds it on, I hope thats not necessary becuase its rusted on.

 

Rear caliper? Screw the piston in.

 

The spring is too tight. I can't push and turn.

 

I have zero experience with the iron rear calipers, but would it be possible to use a large C-clamp to put pushing pressure on it and then screw it in with your hand? C-clamps work wonders to press pistons back into bores, but I've never heard of screwing a piston in (granted, like I said, I have no experience with the non-1LE setups).

 

Well I took it to a shop and the bolt snapped so I'm gonna just get new calipers I guess, hopefully with the Piston installed. That sucks so bad.

 

How hard is it to upgrade the rear brakes to get rid of the iron calipers? Go with the 1LE/LT1 setup if its not too expensive.

 

Tools are avilable to screw the piston in, but if you don't have one, you can press it in with a clamp while you turn the piston with waterpump pliers, being very careful not to pinch or damage the piston boot.

 

Good to know. Not that I'll ever own a car with those brakes, but that I at least know of another tool's existence
