2018 Grand Cherokee Summit - Pulsating Brakes After Rotor Replacement

0

Rachel A. · rep 0 · May 22, 3:23 AM · 1 replies · solved · Question

Hey everyone, I'm having a frustrating issue with my 2018 Jeep Grand Cherokee Summit. About a month ago, I replaced the front rotors and pads myself because I was getting a pulsation when braking. Everything seemed fine for a bit, but now the pulsation is back, maybe even worse than before.

It's most noticeable when braking from highway speeds, but I can feel it even at lower speeds now. The steering wheel shakes a bit too. I made sure to clean the hubs thoroughly before installing the new rotors.

Could I have gotten a bad set of rotors, or is there something else I should be looking at? Any advice on what to check next would be greatly appreciated!
