I think it is time to order new pads for my PC. My backing plate measures approx 5 3/4 inches, so I assume it is a 6 inch plate. I have LC pads right now, and the orange and black pads are concave while the yellow and white pads are flat. I haven't ordered in about 4 years or more, so I am not sure what the best replacements would be. 
Any suggestions would be appreciated. I currently use Prima products and and working on our 08 F150.
