Ok list, the fun just goes on.

New brake master cylinder, new servo, and new reseroir.  Went back to the shop 
the third time, and the servo is fine after a new hose.  They replaced the cap, 
said it was ok, and had fluid on it after the ride home.  About 30 miles.

Cleaned it up, cap on, drive Friday and Saturday, in the garage tonight working 
on another issue, no leak.  An hour later, walk past it and fluid is coming out 
from under the cap.  The cap is so tight that I have to use an oil filter 
wrench to get it off.

Needless to say, I am not a happy camper.  I took the cap off of my old unit, 
cleaned up the new, and put it on.  Sent a note to the shop labled "ball four".

List, it is not over-filled.  Why would the cap get so tight that it is 
difficult to remove?  Seems to me there is pressure in the system that is 
sucking the cap down onto it.  Is this possible?

I am really at a loss.

Thanks,

Craig,

According to the TR6 handbook on page 58 the fluid level should never go below 
the danger line. As pictured it is where the top oval portion of the reservoir 
meets the lower straight portion. So I would guess that any level above that 
is ok up to the bottom of the filler cap.

I just finished bleeding my 72 brakes and I left the fluid level to about 1/2 
below the lower cap.
