B-body calipers on A-body disc brakes? #206542 01/28/09 02:03 AM 01/28/09 02:03 AM

That means it has the 10.87" discs and the slider calipers with the A-body size 2.60" pistons. My question is can I switch to the B-body calipers with the 2.75" pistons? Would I need different caliper adapters? Will it improve my braking if I go to the larger pistons? Thanks for any guidance and info! Some see the glass as half empty, some see the glass as half full. I just drink straight out of the bottle.
