waaaaaaaaaait...
before you go wasting money here there and everywhere...
get a FULL spec of everything done by the previous owner...
if theyve done all that to the brakes i highly doubt theyve overlooked the 16v servo and 22 MC upgrade.
What i would do i check the condition of the discs/pads all round. replace as neccessary
check handbrake cable, adjust as neccessary.
change brake fluid and bleed fully.
if you dont have braided hoses on the front/rear discs id highly suggest getting hold of a goodridge kit (6 line for the inclusion of rear discs) from gsf or ebay.
after all that, you can either upgrade (if the previous owner didnt) to a 16v Servo (get second hand, new units at ECP are listed at 150 odd quid) and a brand new 22mm master cylinder from a mk2 16v or g60 or 16v passat.
youll need to bear a couple of other points such as clevis pin and tee pieces if doing the 16v servo/22mc swap so do your research before
and goood luck
