Default Brake pedal vibration

I jus changed my front brakes and had my rotors resurfaced because they were glazed and started sqealing every time I use the brakes. Now the squealing is gone and brakes work fine except there's a Vibration in the brake pedal that carries all the way up to the steering wheel when coming to a stop from 60 mph, I was in the process of bedding my pads and rotors when it started happening ..anyone have any idea what causes this or has this happened to Anyone that has changed there brakes themselves before ? This is the first time it's happened to me. Any Input would b appreciated thank you

weird possibly the rotors got warped, you may want to take them off again and take them to check straightness again. Or buy new rotors, aftermarket rotors are fairly cheap

Sounds like the rotors are warped......take it back if you had it done at a shop.

Rotors don't warp if they're installed correctly... (course with the timing in this case, perhaps they weren't)

Pedal vibration that's usually mis-diagnosed as warped rotors is uneven pad transfer but if you do a proper bed in, which you said you were doing at the time, you avoid that issue-

Does it do it all the time, or only when you hard brake from 60 to 0?

If you're hard braking and it does it, it's your ABS kicking in, which will give you a pulsing brake.

If it does it all the time under regular light braking, then most likely one of the rotors are are warped.
