The rear right hand side inner pad on my car has been wearing pretty fast. I've replaced the pads in the rear twice in the past 4 months. Both times 3 of the pads were good except the right inner pad. Each time it was down to the metal and grinding away at the rotor. I've gotten new rotors and still same issue after the pad change. Should I look into maybe a new caliper or maybe a ebrake issue? Any help is appreciated as ill be getting new pads for that spot again tomorrow.
