certainly not an expert, but..
...I've never had the pulsating in my brakes. ever. at least not after I do a brake job. Every used car I have ever bought pulsates, but here'* what I do, and it never fails me.. New rotors, generally Bendix, they're not horribly expensive. Standard semi-metallic pads. Clean everything, make sure the hubs are clean, slides work smooth, and where the pads slide against the calipers, clean of all rust, with a little dab of never-seize. Rotors must be cleaned well with brake clean, nofingerprints. Then, I break the pads into the rotors by accelerating up to about 50, braking hard down to a near stop, and repeating this cycle. Old time mechanics have said what ruins fresh pads and rotors is a panic stop then holding the brake pedal down after you stop. If you've ever done this, then you get the pulsating, look closely at the fresh shiny rotor and you'll see a ghost image of the pad stained into the rotor. That'* bad. I'll get the fresh pads hot enough to stink, then drive along until they air cool, then drive normally. Brakes are smooth as glass for the life of them. Just my 2 cents worth Mike
