<< Yesterday I learned that my front caliper assemblies on the TR3 aren't
the originals. They seem to match the drawing in the Moss catalog of the
TR4 caliper. However, Moss and TRF both supply the same rebuild kit for
TR3, TR3A and TR4 calipers, while the dust seals on my calipers are
different.
I can't seem to get the new dust seals to stay in place. The old ones
were held in by metal rings, but I can't get the rings onto the new
ones. Anyone got any advice?
Also, does anyone have an opinion on this conversion? Is it better,
worse, no change? The pads are smaller, and the disc size for the TR4
should be smaller as well, although I haven't yet checked to see if the
discs have been swapped.

You should have the original calipers - the ones with the bridge pipe. I think
any of the various calipers will work on your car and all are pretty much the
same in terms of performance.
It is my experience that the rebuild seals work the same on all the styles -
all use the same pistons. Don't recall any seals held in by metal rings. The
dust seals ride in a groove on the head of the piston and a groove in the
caliper "cylinder".
BTW when rebuilding calipers I highly recommend new pistons. Old rusty pistons
tend to tear up new seals. Brakes aren't something to skimp on.......
