here's a quick primer on calipers. the caliper seals are made of high durometer EPDM. they are square rather than round in profile. when you press your brakes, the pistons don't slide through the seals in a normal braking situation. instead, the pistons extend and the seal STRETCHES a bit. this elasticity is important, as the secondary function of the seal is to actually RETRACT the piston.
EPDM is pretty durable, HOWEVER, if it gets overheated, it will soften. when it softens, it will no longer retract the piston, causing brakes to drag. this, in turn, causes more heat which futher softens the seals & the cycle repeats itself. it is possible that this has or will happen to you. if you fix the system leaks & bleed the system & service the master cylinder and you are STILL having this problem, you may need to replace the caliper seals in one or more calipers.

Solid advice: Will be investigating the second week of May, and will update accordingly. Much thanks for all the advice.
