Low pedal.

Take a good hard look at the calipers & slides(if equipped). Check for binding especially when hot. Make sure the pistons are not retracting into the bore when the pedal is released. Check the hoses too while your there. Master cylinder will usuall cause the pedal to sink while you are at a stop with your foot on the brakes.

I think I am noticing some pedal movement at a stop, It is hard to tell of course. I do not think the master is totally shot. Just bleed past the seals. I will check the other issues as well. What would cause the pistons to retract? The problem did get worse the longer I drove the car, but I would think that a long run not using the brakes would cool them. I also thought warped rotors could force the pistons back, but I feel no pulse in the pedal.
