Warning: I greased my slide pins for 8 years without cleaning the holes first
Did pads and rotors on my wife's 2013 CR-V in our garage in Reno last Saturday and both caliper bracket slide pin holes were packed with hard black crud that no amount of fresh grease was ever going to fix. I had been slapping new lube on top of that junk since my old Tacoma days, which is probably why her front pads wore uneven at 28k miles while mine always seemed fine. A guy at the parts counter asked if I was wire brushing the holes and I just stood there like an idiot. How often do you all actually clean out the pin bores versus just adding more grease?

A wire brush on a drill is the only way I've found that actually gets that baked on junk out. The black stuff turns almost ceramic after a few years of heat cycles, so a pick or a screwdriver just skates over it. I pull the boot back, hit the bore with the brush until it's shiny metal again, then wipe it with brake cleaner on a rag until the rag comes out clean. Only after that does new grease do anything besides sit on top of the crud. Takes an extra ten minutes per corner and saves you from doing pads way too early.
