Next up, I'm going to tackle replacing the front brake pads. I have the BMB pads. I've watched a couple of videos and this one video puts grease in 3 places: 1) the little groves that the pads sit on 2) under the boots on the calipers and 3) the back of the pads where the pads rest against the calipers. Can I use a single grease for all 3 spots or do I need different kinds of grease for the 3 spots?
