Rebuild kit to suit all rear ATE brake calipers, including new pistons and seals. With a piston diameter of 38mm this kit will suit all ATE rear 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 for the dust seals are available separately under item code BR084. 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.
