Strange Brake Pad Wear

Hello All,

I changed my brake pads on my Nissan 200SX about 5 months ago. Recently I heard a squealing noise from the front pads, so I pulled off the pads to change them. However, when I took the pads off, I discovered that both of the passenger side pads were worn most of the way down. However, the drivers side pads were fine.

So I replaced both the brake pads and the rotors (both rotors needed replacing, it should be noted that both rotors were about equally damages, so this would not be the reason for uneven wear). I then drove a few miles to test everything, and discovered that when I braked, a weird grinding noise was coming from the front passengers side wheel. Any ideas what is going on?

I'm not sure why they'd be grinding, unless a stone or something became trapped between the pads and discs...The uneven wear sounds like a patially siezed calliper.

Almost sounds like a frozen caliper. Or possibly even a bad diverter valve. Check for pressure at both calipers (Open the bleeder screws up, have someone press the brake pedal to the floor.) and see which one doesn't have fluid coming out. If it really was a caliper, you wouldn't be able to push the piston back to put the new pads on. if they moved, that would make frozen caliper unlikely.
