These sound like they have already been "professionally rebuilt."

New pistons are probably expensive, and I don't know if the OE 
style with the cutouts are still available. If you go for the rebuilds, 
take a pair of large pliers (Channellocks) and squeeze each piston 
back in its cylinder. If they push back and then pop back out about 
1mm then they are rebuilt to OE specs. Otherwise, the 
compensating pins have probably been broken off inside by the 
rebuilder.

If you do this test, be VERY careful not to let the pliers slip and 
scrape on the rubber boot. If you do, the boot WILL be torn and 
MUST be replaced; you just bought that caliper.

I always rebuild my own, but it can be difficult and there are some 
tricks and tools involved.
