Rebuild kit for front ATE brake calipers, including new pistons and seals. Piston diameter 48mm to suit both 1300/1600 (smaller) and 1750/2000 (large) ATE front calipers from 1967 onwards. Note that the pistons are cup shaped and do not have the original-style central pillar - you therefore need to snap off the central locating "pin" in your caliper body. Once fitted, this new cup shaped piston seems to work just as well - we have sold over 100 of these kits without problems.
Metal spring clips to retain the dust seals are available separatly under BR083. Also note - if you are using this on a Montreal brake caliper with the spacer block, you will require 4 extra caliper O ring seals available under code BR086.
