Re: Front brake pads not touching whole rotor
When you had the pads out did you clean the pucks in the calipers? Did you verify they are all working smoothly? They will build up a brake dust ring and it may keep the pucks from coming out of the caliper equally or at all. If it was one hanging up it would not push the pad into the rotor equally and either the top of the pad would be away or the bottom of the pad would be away, no mater how hard you squeezed the brake lever.
I clean and lube my brake sliders, pins, and scrub the pucks clean once a year as part of a inspection. Just a brass brush and a can or two of brake cleaner and a bit of moly lube for the pins and sliders, and you are golden.
You can also sand you rotors to clean them. You go from the center to the outside, NOT around the rotor. I use 80 grit go around both sides, spay clean with some brake cleaner and all is good to go.
When you clean the caliper you can also make sure the pads are moving freely in the caliper with the clips and pins in place. Clean is you friend in brake work and brake cleaner is not that expensive and works real well. Just be careful around your paint.
