Does your car have a vacuum-assisted brake servo ? If so then
you'll find that is where all your brake fluid id hiding. I had a similar
problem on my car several years ago, where I was losing brake fluid
very slowly, but could never find an external leak. One day I removed the
brake servo, and hey presto, about a pint on blackish brake fluid came
out. I fitted a new brake servo and have not lost a drop of fluid since.

I still hold true that an over reading speedo may be because of
unlubdicated cable. Let me explain. Several months ago I fitted
a HALDA Tripmaster Rally computer to my Midget. For those who don't know
this is a purely mechanical device which measures distance to 1/100ths of
a mile and has the capabilitiy to run forwards or backwards (and a couple
of other features - but I digress !!!)
Anyway, the way this device works is that you have to splice a T-piece into
the speedo cable, and a second speedo cable runs from this T-piece to the
HALDA. The T-piece is 1:1 ration, ie 1 turn in = 1 turn out.

I installed the HALDA as above (according to the instructions), but when
I went out on the rad to calibrate the unit, I noticed that my speedo
was reading 60 at 40 mph. How could this be if the T-piece ratio is 1:1 ?
Anyway I phoned up the manufaturer and they sent me a set of shims which
you install on either side of the T-piece, The only function that these
shims do is to increase or decrease the amount of binding of the speedo cable
as it enters the T-piece. After experiement with several shims I, got my
speedo to read almost true. (I like my speedo to read ~ 5% slower than
true - rallying people may know why !!!!!). Notice that at no time
did I change the ratio of the incoming cable to the outgoing cable, I
only changed the tension of the incoming cable. (I still don't understand
why this worked but it did, I originally also thought that 1 turn of
that cable is one turn of the cable)
So I come back to my original statement of several days ago that a badly
reading speedo may be due to bad lubrication.
