I can give you a few names of Good,Quality pads, but none of them are cheap. The brakes are one of those areas were cheap shouldn't take presidents over good. They are responsible for stopping you your truck and what ever load you have. They are assigned this duty for thousands of miles, and most work perfectly every time you call upon them. This is not an area for Cheap anything, this should instead be an area where you try and buy the best parts available.
I like the EGR pads and shoes, they are the only ones I have used on a Dodge/Cummins. I have used PowerStop's 911 pads on other truck with good results.
