Hello,

So yesterday i took my car to a friends house to replace a stud. We took the hub off and pulled it apart, pressed the stud in and wheel bearing. Now the brake pedal pulses or throbs so im thinking its the rotor because i dont feel it on the gas pedal. But it did not do this before so im concerned, and its pulsing pretty hard. Im gonna take the wheel off and take a look when i get off work but im 99% sure everything is back together the way it should be. Any ideas on what happend? Will turning the rotor make a difference?

 

Make sure you didn't get any grease or oil on your rotor or pads when you pulled and re-installed it, or dirt under the rotor to drive hub mating surfaces.
Clean all with spray brake cleaner.
Turning the rotor will only make a difference if the rotor has runout.
Check it on the car as installed with a dial indicator.
Good luck.
