[TR] TR2/TR3 Brake Problem

[wbeech]

BTDT, My experience was the same as Randall's, taking some pressure off the
line freed up all wheels.  I adjusted the 'Primary' cylinder rod maybe 1/4",
don't remember if it was in or out, problem solved!

My guess, the return valve inside the MC is not opening, for whatever
reason.  Might be a misadjusted pushrod/pedal stop; could be the pedal
hanging up (binding), or even a missing pedal spring.  With the valve
closed, normal expansion as the fluid heats up can apply the brakes.

When it happened on my Stag, the MC piston was binding in the bore just
enough to keep it from returning far enough to open the valve.  (Apparently
some gorilla had used vise grips on the piston and not bothered to even file
away the damage afterwards.)  Loosening the line at the MC and letting out
just a few drops of fluid got the brakes to release (proving it was a MC
problem) and we drove another 300 miles or so without any further problem.
