Just as 5Twins and W W explained, but if they are really stuck u might have to resort to pumping them out with a grease gun. i did some about a year ago and when i saw grease come out of the one i held it in a vice until the other came out. A little more messy than air but somtimes u need a little more omph.
If you use grease , how do you completely flush the grease from the caliper? Mike
