I would choose a local mechanic you like, brake calibers should be lubed occasionally and brake fluid should be changed out per your maintenance manual. I do mine every few years though, my truck is only used for towing and hauling, so low miles per year. I like OEM rotors, or some premium name brand ones. On a one ton I rarely need to replace them ever. Only if they get damaged for some reason, warped, cracked, stuck caliber does damage or whatever. I had a front right brake caliber lock up on me from internal corrosion, but the rotor survived.
Lots of variables on pad life, average driver probably will get 60K to 120K out of the front pads on a late model one ton. Exhaust brakes help greatly too. If the rotors are in spec I would keep on using them. My current pads on a dually are about 50% gone with over 50,000 miles on mostly rural rods. I put on the Hawk brand pads early before the OEM's wore out, not much difference. The Hawk pads I have now seem to be nosier maybe, not much dust though. My rear pads last forever it seems, I end up changing them due to the age! Auto parts store pads are fine, I wouldn't buy the fancy ones again.
Its an easy job to lube calibers and check pads, I do my own brake maintenance. I usually get 150K or more from brake rotors here in the SE. Mine rust out from trips on salted roads before they wear out.
