I've got a leak coming from my clutch master cylinder on my 90 Carat.
(fortunately not the brake m/c).

It appears to be coming from the top, as the "piston" and boot are soaked in
fluid.  The rubber accordion boot is connected at the top to the piston but
is loose at the bottom and exposes the piston when the pedal is depressed
(I'm guessing this should be connected, but is probably unrelated to the
actual leak?).

So, assuming the m/c needs replacement, how difficult of a job is this for a
novice mechanic? (I haven't done much more than routine tune-up stuff).  My
shop quoted around $250, but it looks like the part is only $50 from Bus
Depot (anything additional parts required besides brake fluid?).

Advice appreciated.
