It's been a long time (I love DOT 5 !), but aren't the TR3A calipers the
ones where the dust seal has to be fitted into the caliper bore before you
insert the piston ? Then you stretch the smaller end of the seal over the
rounded end of the piston, and push the (lubricated) piston into the
caliper. The small end of the seal will fall into the groove in the piston
when the piston is pushed home in the caliper.
Swaps are common, so be sure you have the seals for your calipers. At some
point, the seals and calipers changed so the seal fits over a lip on the
caliper, rather than under.
