I put brake pads on my QX4 about a year ago. Now my wife thinks they need more, but I checked and the pads are fine. How do I get the brake pedal to pump up? When I press the brake pedal it goes almost to the floor. I also noticed the passenger side pads are slightly touching the rotors always, but the drivers side rotors are not. (I noticed this when I took the wheel off to inspect the pads)
