I've done a few Vettes... or Chevy's for that part. The Silverado's were always a beast with the lock-tite!
BTW you can use a C-Clamp and Chanellocks for the rear caliper piston.... keep enough force on the piston and spin it with the chanellocks, then tighten the C-clamp some more... it's easy easy... and takes the pain out of using that tool to twist while you have to push!
