Is the piston tool needed?
Hi guys!
I've rebuilt a few calipers before, but never corvette c3 calipers.
i see there is a special tool for sale to rebuild the calipers on our cars.

Is this needed? I am going to use original lip seals, No O rings. I've never seen a tool like this before on other calipers.
Any insights are welcome

The idea behind that tool is to make sure the seal lip stays pointed toward the back. Not really needed. IF the lip rolls as you install the piston, it will be hard to turn. Correctly installed, the new seals and pistons will rotate in the bore without much effort. Lube them all well with brake fluid.

Check the cylinder bores for wear or rust or pitting. I'd hone them them make up your mind. I always hone them anyway. There is a similar sleeve for your crank if the snoot has lip seal wear. or use an offset timing ci=over seal. I don't think anyone can give you absolute suggestions without seeing your calipers.
