Brake Pedal Stiff When Weather is > 90 degrees

[jlagnese at massed.net]

When that happened to me the pedal became hard and wouldn't go down very 
far.

Under hood heat buildup caused MC warpage that made brakes remain engaged 
after the pedal was released, especially in 200q20v models. I don't recall 
that making the pedal hard. Does the CQ have a "bomb"?  Failing accumulator 
can cause a stiff brake pedal.
