<DIV><FONT size=2>'Floating' calipers as used on the MG ZS 180 for example do
only have a piston one side. When the pad that side contacts the disc the
body of the caliper is pushed back, on sliding pins mounted on a fixed
carrier. The caliper wraps round the disc to pull the other pad against
the other side of the disc. I had my doubts about the sliding pins, but
despite a number of corroded parts on my 14 year-old ZS - far more than on my 40
year old MGBs - those haven't yet given me problems, it has been the pistons
themselves, as on the MGB calipers.</FONT></DIV>

<DIV dir=auto>I have heard of but not experienced, floating calipers. Do they
have a piston on one side only? Seems a really silly place to cut cost
corners!</DIV></DIV></DIV></BLOCKQUOTE></BODY></HTML>
