Kendall, Ron:
Depending on the depth of the damage, honing is a legitimate and
reliable technique for repairing hydraulic cylinders. It can be applied
to stepped bores (it just requires two different sized hones, depending
on the size of the step). Sleeving is only required if the damage is
severe and honing cannot restore a smooth finish to the cylinder wall.
My clutch slave cylinder looked pretty bad, and I thought it was toast.
I wanted to just pop a new one in, but slave cylinders from Moss and TRF
would not fit the mounting plate without using a grinder. Nasty.
Obviously there are some cases where sleeving is not feasible,
although I would argue that sleeving could be done on a TR MC. It just
requires 2 different sized sleeves. The step itself would not be
resleeved, but it is not used as a sliding surface, so it shouldn't
matter. IMHO, of course.
It would probably be cheaper to get a used, rebuildable MC and
hone it, than it would be to resleeve or buy a new one. Used ones are a
dime a dozen from wrecking yards.
Despite dire warnings that the new MCs were going to disappear,
lots of suppliers still seem to have them. At least, I see them all the
time on eBay. $200 will get you a brand new one complete with fluid
reservoir.
Cheers,
Vance

Hi Ron,
I have to say that based on my own personal experience that Apple
Hydralics is
a NO GO on the Brake MC rebuild for a TR-6 -- I wanted them to brass
sleeve it
and they said they couldn't because of the "stepped-bore" on the inside.
I'd
say just get a new one or go to a place that actually will put in a same
diameter sleeve.
That said I did have my brake MC honed at a local shop and then I put in
some
new seals. I didn't expect it to last much more than 3-4 months. But it
is
still leak free a year later (not driven too much) So YMMV.
