Replaced both the clutch master cylinder and brake master cylinder within the past 4 months.
Last weekend I installed new front rotors and pads. When removing the old pads I noticed the left front pads were unevenly worn. What would cause this? a bad sticking piston within the caliper? Or would it be caused by the pads not freely floating on the two pins? Should these pins be lubed with high temp/antiseize grease or common substitute?
Reinspected the entire hydraulic system for any signs of leaking but found nothing.
 Now when I apply the brakes I frequently loose my brake pedal! It goes soft and I must pump it up. Also when I am turning I here an occassional squealing and or dragging. 
How do I determine if I need to replace a caliper?
Could my problem be as simple as just bleeding the system? Could my master cylinder be going bad ? AGAIN !!!!!!!!!!!!!!!! 
thanks
