I changed the OEM pads at 80k with axxis ultimate pads, no grease no problems. The axxis pads have anti squeal shim on the back already. I didn't turn the rotors either, no problems.
I read about that you need to clamp the brake hose and open the bleed valve while pushing in the piston, otherwise you may ruin you ABS or master cylinder because dirt may get in them. Helm doesn't call for that so I didn't do that.
