High speed braking vibration
Help me diagnose. I have high speed braking vibration. Only occurs at 45+ speeds and vibrations can be felt in steering wheel and brake pedal. When I brake at slower than 45 I do not get any vibration

Sounds like warped rotors to me. I would have them resurfaced or get a new pair. Do you notice any noise from any specific wheel when stopping?

I have the same exact problem, so I just got new front rotors and pads. I'll let you know if that fixes it as soon as then go in. It'll be a couple of weeks though.

Did you check all the caliper bolts and make sure the rotor is sitting flat? Really sounds like warped rotors. Could dial indicate the rotors while on the car if it comes to that.

Key word here - seem. Its pad material transfer.
You can try to take 120 grit sand paper to the rotor surfaces and then re-bed the pads. But if that does not work, you will have to get them turned.

So deposits of the pad on the rotor? I will try sand paper. Also the rotor is free moving right? Just held on by the lug nuts and pad? I noticed that I can pull on the rotor to get it to wobble

It stops wobbling when you torque the wheel and lugs on.

No. "Warped" is the feeling you are getting in the wheel/brake pedal. They are not warped at the rotor surface level. It is pad transfer.

Doesn't matter how many times you bedd them. It's matter that if you did it right or not.
Vibration, did you notice it right after replaced the brakes?
