The brakes on my bike have been making a 'not good' sound for a while now and I've been ignoring it. Until yesterday when it became obvious I should look at them.
I think I need new pads.

Down to metal on one section and no wear on the other end.
I found the receipt for the bike when looking for info on the type of brakes.
It'll be 10 years since I bought it new back in Nov '13.
This is the type of brake I have on it.

Any recommendations as to where I should look to get new pads for it?
The local shop doesn't open until 10 this morning so I thought I'd find out what you guys think before heading on down there. I tried the shop I bought it from yesterday but they weren't open. Not sure when they'll be open either. Probably should have read the sign on the door. That shop is the little guy in the big vs little shop battle around here.
