Rebuild kit for front ATE brake calipers, including new pistons and seals. With a piston diameter of 48mm this kit will suit both 1300/1600 (smaller) and 1750/2000 (large) ATE front calipers from 1967 onward.
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 will work just as well.
Metal spring clips to retain the dust seals are available separately under code 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.
