[Healeys] Brake issue

[Perry]

High pedal, meaning that the brake pedal does not travel downward when applying foot pressure, is indicative of wheel cylinders or caliper pistons not moving in their bore.  The fluid in the master cylinder has less space to travel to and therefore remains high. Since there is more heat coming off the front brakes a suspect the problem is in that (front brakes) area. I suppose if there was a blockage in the master it could act the same way but don’t remember that ever happen to me previously. 
But I’ve been wrong before…..

I'm going for a short ride in a little while to a destination nearby and I will carefully observe if the pedal gets high and hard and if the brakes drag, etc.

If there is a collapsed line the condition should appear relatively quickly don't you think?  OTOH if it does not appear before the car heats up that might be significant. 
 
I am sometimes a sucker for easy solutions....

NEWSFLASH:

After letting the car sit for a few hours I just checked the pedal and it has gone back to normal with an inch or two of motion, same as it was before i started out this morning's drive.

At the same time i adjusted the pushrod length a few months back I also removed some exhaust heat-shielding and have not yet gotten around to replacing it.  Given the high ambient temperatures I wonder if heat is getting to the MC, causing the brakes to somehow stay partially or fully activated?

During a drive today I noticed that the brake pedal is higher and harder than normal and as I come to a stop it definitely feels as though the brakes are dragging, plus there seemed to be a lot of heat coming from the front brakes.

I suspect a problem with the master cylinder but would appreciate any suggestions as to what the issue and fix might be.
