Vibration at 55mph after brake pads replacement?
Hello everyone,
I've replaced both brake pads last week and I'm experiencing a noticeable vibration at a constant speed between 55 and 65mph right after the front brake pads replacement. Didn't notice any vibration when I left my car at the shop to let them perform a replacement of rear brake pads in which I'm assuming that something went wrong during front pads replacement (because fronts were replaced the next business day). Even the rear seat passengers can feel the vibration, although it is more prominent on the front seats. This happens with no pedal engagement, so basically the vibration is present during coasting at a constant speed. Going beyond 65mph or below 55mph gives no problem at all, but the vibration is present at 55mph the most and gradually goes down until it hits 65mph when it disappears. I did some research over this week and it seems like the existing problem corresponds to the brakes (either it be warped rotors or calipers not engaging properly. I also found out that the car might need re-balancing of the wheels/tires to let the vibration go away but it was quite odd given that mine was performed with a road-force balancing last week along with replacement of rear brake pads. Maybe low thread on rear tires, but I doubt it'll be the case since the vibration suddenly came up after the replacement of front brake pads. I need some insights from you guys. What might be some culprits? Any help would be greatly appreciated 🙏🏻 Happy belated thanksgiving yall!

It could be a lot of things, unfortunately, like worn tires or poor alignment. My first guess would be the tires being unbalanced, but you've just had them balanced. Maybe have the balance checked to make sure it was performed properly?
I highly doubt it's your rotors, as you'd have felt them long before switching pads. I'd say your best bet is to bring it back to the shop and raise your concerns with them. |

Have them also check the tires over very carefully.
Had a similar problem once after BMW service and it turned out to be a large diameter screw/bolt that one tire picked up from the service bay floor. It wasn’t long enough to cause a puncture, but big enough to put the tire out of balance. |
