Pedal vibration	Sign In

I got a 2005 Grand Cherokee 4x4 Hemi.
I have just changed the rotors and pads front and back, I got a vibration feeling in the brake pedal. This was the same feeling I had before I changed all the brakes. Could air in the brake lines cause this problem, I have not bleed the brakes but I did change out all the old fluid in the resovior it was really dirty I sucked it out with turkey brasher. It had little black pieces in the cup but dissolved when I touched them. What do you think
Thanks

Changing the brake pads isn't going to do anything for a vibration/pulsation type problem. It's likely distorted rotors and they would have to be replaced if they are the cause.

A maybe to check as the issue is there with both old and new rotors? Are the hubs where rotors go on nice and clean of defects or rust? What I mean is if rotor can't set flush and true on hub you get the same out of "true" feel if so.

Hard to believe but not impossible that new rotors (could be just one) isn't true but unlikely in the same way as the old ones,
