I've got a 2003 SuperDuty F250, and recently started getting some pedal vibration. I went on RockAuto and purchased Wagner's heaviest duty brake pads on sale for $45--for both axles. My front rotors needed turning.
The mechanic didn't want to change my front pads, as they had little wear--Hawk LTS brakes with about 60K miles. When I bought those brakes years ago, the Hawks had the best reputation of any tires for my 3/4 ton truck.
E&B advertises having a extra heavy duty pad and rotor combo, and I'm sure they're good. Most of the other popular brand pad manufacturers have 3 different brakes for 3/4/1 ton trucks for different uses.
If you're towing heavy, I'd tell you to just buy one of the really good brand of brake pads--often better quality than OEM.
