Subject: [Mg-t] brake fluid level question
Message-ID: <20120117.160042.8709.6@webmail-beta02.vgs.untd.com>

   The TD handbook says to fill brake master cylinder to a level 1/2 inch
below bottom threads of the filler neck.   That leaves a large volume of air
above the fluid, far  more than would seem to be needed for expansion.
Totally T-Type 2 (Issue 10, February 2012) has an article by a TF owner who
rigged a separate overflow bottle to his MC, connected at the back end with
banjo fitting, so he can check level and fill from under bonnet, instead of
through the hole after removing the rubber plug under the carpet. Would this
not fill the MC completely?
   Why would MG have specified such a seemingly low level? Does it matter?

The master cylinder cap is vented via a hole in the side of the hex, so
sloshing causes leakage if the fluid level is too high.

Interestingly the Morris Minor, which uses a very similiar master cylinder, 
has factory service instructions to fill the master cylinder to the bottom 
of the threads for the cap.

With a remote separate overflow bottle wouldn't the fluid leak out 
continously from the cap breather and/or a slightly imperfect cap sealing 
washer?

No.  The separate filler bottle kit made and marketed to the morris minor guys has a new end cap with nipple, a top plug, the filler hose, and the rover reservoir.
Not only does it work well for the morris (mine has a TD m/c on it for more volumn for the front disc brake mod.
I've installed the kit into several TD's and the owners LOVE it!

And the Handbook text and Workshop Manual illustration are contradicted by 
the TD fluid reservoir cap, which says "Fill only to bottom of neck"! --  
which I've been doing for the last 30+ years, and always wondered why I 
needed to add fluid first thing in the Spring but could never find a leak in 
the cylinders or lines.  Guess I'll change my ways and leave it 1/2" low....
