[Healeys] update to BJ8 calipers leaking

Recently I asked for help on caliper seals that wouldn't seal and received a bunch of good advice. I finally went through everything successfully and thought I'd pass on the results.  The seals I had from Moss didn't seal and didn't look too good- sort of a scalloped look to the cut edges.  I ordered a high quality kit from the Nocks along with the O rings needed to split/ reseal the calipers.  When I split the calipers and was able to get a good look I found lots of corrosion and roughness in the grooves that hold the seals. I cleaned and ground those grooves smooth again, installed the new seals, and put it all back together with a little silicone brake lube. With the calipers apart it's a slick and easy job. I feel stupid for doing it the hard way in the past- those O rings are cheap. Now everything works (and stops) like new again with no leaks.  Also, in fairness to Moss, despite the appearance of the caliper kit, I think they would have sealed fine
 if it wasn't for all the corrosion/ roughness I left in the grooves.
