I use a 75 cent block to keep my pistons from extending too far (3 quarters taped together). I've never popped a piston using this method, and then I soak a shoe string in isopropyl and "floss" around both pistons (2 piston XT brakes). I now have 4-piston Zee brakes so I will either try to extend my 75 block, or see if I need to double my investment to two 75 cent blocks. The shoe string floss works exceptionally well.
