pump the brake till it pumps it out... while you are there you can pull out the piston and clean it. also remove the rubber seal, wipe it down really good, then lube it with some ATF, clean the bore it goes into and replace the piston... then you can rev bleed the system... here is how you do that... fill the resivor wiht your brake fluid... put your piston in place and slowly press down on it... (be sure your cap is off your master cyl) press slow so you dont spray brake fluid everywhere... you will see bubbles in the master, once they stop and you get strait fluid your sytem is bled... in reverse... works great! plus it allows you to clean your pistons easily... there is a small plasic washer on the back of the pads that tend to go bad... and stick to the old pad... that is prob what has it on there... i also use high temp pad grease on the back of pads out of habit, does not need it but does not hurt it... while you have them apart. pull off the support arm... pull the pin out and clean it, then use some marine grease or honda grease on there... will be like brand new brakes (just di a set last night so it is fresh in my mind)
