Thanks for all the good advice, guys. I'm a woodbutcher, not a
mechanic, and the only time I spend with the MG is when I'm behind the
wheel, not under the car. Bad form, I know, but I'd rather be making
sawdust than tinkering with the car. I'm gonna take your advice and see
if what's in the car mixes with water and then fill 'er up. I just want
to run her out to the mechanic for a full brake inspection and let him
get to the root of the problem.

I've got a 1952 MGTD. When I put her to bed last fall, the brakes were
fine. Now the peddle goes down to the floor. First step is to add
brake fluid, but I don't know what's in there now. Have seen plenty of
cautions about mixing fluid types. Any way of figuring out what's in
there now?

TIA
