Started feeling a pulsing in the brake pedal awhile ago. Drove it until I couldn't bear with it any more. Bought new pads to change. When I took the old ones off. They were in great shape.

Put the new pads on anyhow, same problem. Changed the rotors thinking maybe they were warped. Same problem. Rear rotors look good.

Pulsing isn't that noticable (if at all) in the steering wheel. Is there anything sensor-wise?

At 10 MPH if you push the brake slightly, you can feel a slow, rolling pulse. At 50 MPH, it is a very strong, steady pulse that shakes.

Machine or replace the rear rotors, that should take care of your problem

Took me awhile to get the time to do it, but I wanted to report.

The rear end was the problem. The inside pads (the ones I couldn't see) were worn down completely. Replaced rear rotors and pads and the problem disappeared completely.

Thanks.
