Paul, wouldn't a seized piston cause the pedal to need less travel to reach full pressure?Needing less fluid to fill the single piston area?


That would be too simple. It's more about the piston that's moving contacting the rotor and twisting the caliper out of parellel with the rotor since there's still space between the other edge of the pad and the rotor since the piston isn't moving. I'll bet the pads are worn at an angle. If the piston is seized it needs to be freed up anyway, I'll bet a nut that solves it.
