I finished putting new rotors and pads in yesterday and for some reason I have a weird chirp, squeak from the Left rear.... should I be able to see both pads from the little caliper window or is it normal to only be able to see the rotor and inboard pad? The pins were sliding smoothly so I don't know what else the squeak would be? Also, wondering if my axle seals are leaking? Or if that could be brake cleaner runoff? It's on both sides so makes me hope (fingers crossed) its brake cleaner?
