Absolutely; wasn't positive until you mentioned the 'hum'. Bad bearings first warning sign is usually the humming noise before the vibration but since you have both, I'd be shocked if it weren't the bearinig, especially since you've got new rotors. In the past, a badly turned or warped rotor would mimic a bad bearing. Best of luck.

I have a 2007 Pontiac Torrent FWD with a violent low speed vibration. we have replaced the lower control arm assembly and the hub bearings along with the brake pads and rotors.


Struts would not cause vibration problems, A CV joint could, turn your vehicle in a parking lot hard right, make a circle than turn left make a circle ,if you hear a noises you have a cv joint problem. If you feel vibration on the steering wheel its in the front, if you feel it in the seat its in the rear.
Tires out of round & Balance very common as well brake rotors cause vibrations.

I have no brakes


It can be issue with master cylinder or the problem is there is still some air there in the system that has to be bleed. Or else the parts replaced are not aligned properly/.I suggest everything back.

For the last few weeks been having a problem with my brakes whenever i press on my brakes there is a vibration that goes through my brake pedal? What could cause it to vibrate?


its possible that if you had the wheels off and put back on the wheel nuts are not tightened to the same torque,this can cause the vibration as it has caused a warpage in the rotors or drums.also the brake rotors or drums may just be warped on their own.

Truck shakes when brake is applied upon slowing down it gets shakier until i let off the brake and pulse the brakes till truck stops


A common cause for the vibration when braking is when front brake pads are replaced, but the brake rotors were not resurfaced smooth. Overtime when braking, the new pad will wear into the rotor that was not cut. The uncut rotor, having high and low spots when turning, will cause the brake pedal to vibrate/pulse when stopping.

2006 Satrun Vue, experiencing a vibration wehn brakes are applied and then when brakes released a bit of vibration is felt at take of as well. The front rotors were replaced and turned since we have owned...


I would check the rear brakes drums, they may need to be turned. The front rotors may have warped again, with turning the rotors, it removes metal from the rotor which leaves the rotor with less metal to dissipate heat, and the rotor will warp again when they get hot.

07 camry brakes clatters when brakes apply, Can you help with the fix??


If you are saying the brakes chatter or there is a vibration when applying the brakes your rotors are warped. Remove the pads, have the rotors turned at a machine shop, and replace the pads with new ones, even if they look good. Warped rotors are caused by excessive braking at high speed, riding the brake pedal, or not correctly torquing the lug nuts to the correct lb/ft when installing the tire/wheel. Your owner's manual will list the correct torque which will be around 80 lb/ft. Make sure anyone removing a wheel use a torque wrench and torque them correctly.

Brakes just dont seem right.. dealer said they put on new front rotors when i 1st complained.. but only got alittle better, brakes still seem like i have to apply with alot of force, when with my wifes...


If the vehicle has rear drum brakes, I would check the adjustment on them, if they are too loose, this will cause the brake pedal to go down low.
