I'm experiencing a slight vibration when hard braking at higher speeds (30+). It is more of a pulsing feeling in the steer wheel than vibration...best way I can describe it. I have just installed Power Stop rotors/pads on the front, had all tires balanced and steering/front suspension inspected. Everything appears to be in good working order so not really sure what to look at next. I know the back rotors/pads need replacing, but not sure that would cause the vibration in the steering wheel...those will be replaced next week. Could this be a caliper or ABS problem? Any advice is greatly appreciated!

 

Could be a spot of grease on a front rotor.

 

Did you follow the procedure to bed the pads? There are stops from different speeds followed by extended drive to cool. The procedure is printed on the box for the pads. If not, I would start there.

Also, I did have a rear rotor contribute to the issue you are describing. Ended up having it turned under warranty. Later I replaced all 4 with powerstop and followed the bedding procedure.

 

Improperly torqued (wrong sequence) or especially over-tightened front wheel lug nuts can cause a slight feeling in the steering wheel when braking.

 

Thanks for the replies!
I will check, but pretty certain the rotors were really clean before I put the calipers back on. I made sure they checked the torque when my tires were balanced so pretty sure I'm good there. I also made sure the follow the brake in procedure once the new rotors/pads were installed (55 to 10 x5 and 35 to 5 x5, 5 mins of moderate driving). I'm going to look at it again this weekend. I appreciate the comments!
