I always buy Napa’s premium line. There is one step above that for rotors that are more performance oriented, cross-drilled and all that, but not worth the extra cost. When choosing rotors you can compare different quality levels by pinging them and comparing the note or tone of the ring it makes (good steel) or dull thunk (cheap metals). When its a safety or strength issue, I avoid steel products made in China - tools, graded hardware, and brake rotors are some examples. Too many “counterfeits” and cheap knock-offs.
For pads, I always use the Napa premium. I’ve done many brake jobs on trucks which I’ve used for towing all sorts of heavy trailers, and never had an issue. Ford had a rotor problem in the 90’s (cheap, thin rotors that would warp just after the warranty period ended), but Napa brake products have always done the job with no issues.
