2008 Brakes grabbing

[David Heck]

I have a 2008 expedition. Just replaced front pads and rotors however, my brakes still pulsate or grab when slowing down. Could this be the ABS system? Or possibly rear brakes and rotors? Replacing the front rotors and pads did not seem to help.

typically pulsating brakes is from warped rotors so i would take a look at the rear.

I’ll check them for sure but it seems like someone is stepping on and off the brakes not than pulsating. Thanks

I would do the back regardless. Ours were just about as shot as the front when I did ours...

If you can borrow a dial indicator, you can remove rear wheels, put back 2-3 lug nuts, rotate discs. Their should be .004 or less run-out. Do the same on front. As far as Abs, run the codes. I think you'll need an advanced scanner to do that. Any better brake shop can do that if it does, and you don't happen to have. You probably have a sensor or something that's not functioning right. Is the Abs light on?

Did you lubricate the slider pins and where the pads slide on the caliper bracket?

Make sure the rotors are seated properly with no rust on the hub, and that the wheels are secured evenly. If your new rotors came from a chain store and cost $19 each, throw them out and buy real ones.

Try stopping the car, or slowing it down with the emergency brake. Hold the lever out and step on the pedal. That will tell you if the rear drums are pulsating.
