Tom -
Get hold of a brake cylinder hone from a local auto parts store or tool
supply house and use it in an electric drill to clean up the cylinder walls
of the calipers. Don't overdo it. If they clean up easily with no visible
pitting, you're probably OK. Be sure to replace all of the rubber parts
after lubricating the new ones in brake fluid.
As long as the calipers clean up with no pitting, you can probably spare
yourself the expense of new ones.

===========================================================
I am an MG rookie just starting to restore my 74 Midget and would
greatly
appreciate some advice regarding my brake repairs. My recently purchased
Midget
had been standing for about a year or two (actually passed inspection in
1994),
and the brakes are bad - low stopping power and locks up R front wheel.
I have started on this project by removing the left front caliper (the
pads look new on both front wheels and both front rotors are slightly rusty
but
don't look too bad). Having removed one of the brake pistons I found a fair
amount of rusty sludge in the cylinder and some fairly light corrosion on
the
piston and cylinder. Neither feel pitted or scored and it looks like I
might
be
able to remove the surface corrosion with something like Brasso. Is this a
completely stupid idea? The manuals I have all suggest replacing any
caliper
with corrosion but I do not have the experience to judge what is or isnt
acceptable. Thanks for any advice.
