I have had a similar issue before with junk pads. It was on a unrelated platform but it was terrible. I would stand on the brakes and it felt like brake fade. They worked but nothing I felt “confident” stopping fast with. I swapped pads that were probably some off brand to a regular wagner or raybestos and i might have cut the rotors and it was pretty much normal after that. Had me confused for a while. On my 3/4 ton I keep the original drums adjusted up and if I hit that pedal you are going into the windshield. It will 100% lockup the brakes at 55mph. I drive it carefully just because of what it is but I cruise on the highway with it at 65-68 and have no problems on off ramps besides a little pulsation thats only really noticeable above 60mph stops. I have no idea what brand shoes are on it but they are from 70’s or earlier. They looked fine so I ran them. It does have all new hydraulic parts front to back including a dual master.
