Default Brakes Pulsing - changed all rotors/pads - now slightly worse....

I have a 2008 2WD Hemi with just over 80k miles. At about 60k, my brakes started pulsing, so a few thousand miles later, I changed the front rotors/pads. Nothing changed. Yesterday, I got around to doing the rear. Same thing - new rotors/pads. This actually made it slightly WORSE.

The caliper plungers all *seemed* to compress back into the calipers with about the right amount of force. I have plenty of brake fluid.

Ideas? Very annoying!

Thanks!

Maybe your brake lines are starting to collapse? Maybe replace them with the high quality steel braided lines.

Even tho the calipers felt fine you could still have one sticking

Also, don't just assume those rotors were not warped a little out of the box. I just did the rears on my Grand Cherokee after I had a caliper decide to lock up - taking out the pad and rotor. Brand spanking new Autozone rotors were slightly warped out of the box and I had to turn a hair off of them to get them right...

bad tie rods can give the same feel. If the truck gets bouncy when you're coming to a stop then it could be the tie rods.

I agree with worn tierods. If there's any slop in the joints they will shimmy back-forth when the brakes are applied. Most of the time, they will shimmy and gradually go away or get worse until you slow right down. They generally wobble at higher speeds which makes you think they are rotors.
I'd grab ahole and vigoruosly shake. If nothing, then use a pry bar to see if there's slop. They should barely move with a bar and not at all by hand.

Dont forgot about the lug nuts. Did you use a torque wrench to tighten the lugs evenly to the same spec?

I have had warped rotors right out of the box before. I put pads and rotors on my Durango and the new ones were worse than the ones I took off. I had to resurface them and them it was smooth.
