Bit of a reply from the dead, but i just purchased a rebuild kit from Brakecrafters for my '93 Mk.2.   
The kit was top notch, the seals fit perfectly.  i also liked the fact that they included a small tub of 
assembly lube for the seals. 
I also bought a set of pads and like those as well....i'll be getting a set for the front now too. 
have a good one, 
Bryan
