I need new calipers for my 116 Alfetta; 1975 transaxle. I tried to rebuild mine but the bleed screws disintegrated a long time ago and are completely rusted/seized into the calipers. I tried everything, including a screw extractor, but broke around 5 drill bits and 2 extractors on the first screw. Just the bodies should be fine, I can get the calipers the rest of the way disassembled, but if you have some that need rebuilt I have all the stuff to do it. New ones are acceptable as well. Cheaper is better.
