Sorry for the delay in responding, Wayne's World, I've been out of town for a few days.
I seldom recheck if the lube is there. I go through front brake pads pretty quickly. I generally average a little over 30,000 before I have to change out the front pads.
I have also used Sylglide and I like it best of all the greases I have used for this purpose. But whatever I have used, the front pads always wear evenly IF I use the grease. The first time I did a brake job, when I first got the truck, I forgot to use grease and there was a huge difference in pad wear, as the Caliper didn't move correctly.
