Did it pulse BEFORE you slapped pads in it?
Well you deleted your post... so whatever makes you happy.
I guess we will have to agree to disagree... arguing on the internet is pointless.
I'll agree this one is weird. Anything felt through the steering or not is more about front vs rear brakes than it is drums vs rotors, but I'm sure most of us knew that.
My experience suggests that both rotors may be slightly warped, possibly not enough to really notice individually, but that this is a "phase" issue, and both high spots need to hit close to each other before it really gets going. So going through a turn moves the two high spots in relation to each other, and makes it less noticable. That would explain why it seems to come and go.Here is a test for warped rotors - Get the truck up to about 20mph, let go of the wheel and press the brake pedal, if the truck turns or the steering wheel wiggles, it is your front rotors, no doubt. but if the pedal moves up and down, but the truck stays in a straight line, it is likely, not the front rotors.
OP said "brakes started to pulse" after he put new pads in and "pulsing" started a few days later, he cleaned them, it went away and then came back. No way in hell he cleaned off the "warp"
pulsating is "usually" associated with bad rotors, but in this case it comes and goes with a wire brush cleaning.??? Sometimes the easiest fix isn't always the right fix.
Who knows, maybe I'm overthinking it,
I can feel it at the pedal and sort of all over except I don't feel it through the steering wheel. At 70 mph the pulse is like a machine gun in frequency. I never said it goes away and comes back in a few days. I said I cleaned the back side of the wheel and the mating surface on the the rotor (flat area around the lugs) - not the rotor. The pulse went away for a few days after the clean up and removing the wheels and now its back. It doesn't randomly come and go.
Correct: I wasn't saying it comes and goes randomly. I meant it went away after you cleaned the hat, then it came back a few days later. Warp does not go away. Unless like adsm08 is saying is true and Now that you said you feel it in the whole truck, it could be Warp.
Do the steering wheel test, even though you don't feel it in the wheel.
