Hi Jeremy,
Well, I recently did a caliper rebuild on my 72 B, and it was centered =
when I put it back on. It seems that it would have to be for the =
caliper to work correctly (i.e.. keep pressure even between both =
pistons). I did not however, dismantle the rotor from the hub, so I =
assume your problem is somewhere in there. I can't think of anything =
else, but then again, I haven't gobs of experience to offer you, =
either...
Regards,
J

Subject: Brake caliper help needed
Hi everybody,
As some of you may recall, I already made the mistake of buying
rebuild kits for my MGB's old brake calipers and then deciding I needed =
new
ones, but that's all behind me now as I got my rebuilt calipers from =
Moss a
few days ago (thanks to Dick B).
Anyway, I'm in the process of installing them on the car, and I'm a
little confused. When I bolted one up to the axle, the disc was not
centered in the caliper (see my cheesy ascii art below), and the caliper
seemed to make a slight contact somewhere with the disc even with no =
pads
installed.

Well, I went ahead and put the pads in. Due to the non-centered
disc, the inner pad slipped right in without even touching the disc, and =
the
other I had to push pretty hard to get it to slide in between the edge =
of
the caliper and the disc. With the pads in, the whole wheel will turn =
but
not very easily.
I went and did the other side, to see if there was a difference
there, but it went on exactly the same as the first (disc off center in =
the
caliper towards the front).
Unfortunately I don't remember what the old calipers looked like
when I took them off the car a while ago, and I'm no brake expert. Is =
this
off-centering a problem or is it normal? If it's wrong, any ideas what
could be wrong? I checked the obvious things I could think of (putting =
the
caliper on the wrong side, installing the wheel hub incorrectly on the =
axle,
or installing the disc incorrectly on the hub) and didn't immediately =
find
anything that looked amiss.
Thanks for any suggestions! Once I get this figured out, and get a
couple more brake lines in place I'll actually be able to put fluid in
(DOT-5, I'm not going anywhere near my nice new paint job with DOT-4), =
bleed
the brakes, and have the first complete system in my restoration project
working again!
