Re: Vibration When Braking.. Out of Round Feel In Brake Pedal??

Have you taken a wheel off? I have seen guys over torque lugs and have it screw up their rotors (warping). That would give you that feel. Or they take off the rotors and put them back on slightly crooked and crank the wheel down.
You might also want to check and make sure you don't have a high spot on a rotor, or some brake dust or other crap trapped in there. Blast your wheels out good with a pressure washer (like at a do-it-yourself car wash) and see if it dislodges anything.

I haven't removed a wheel yet it been at the dealer once for an oil change so they shouldn't have removed any wheels..

Couldn't tell by your description just what an "out of round feel" is.
Sounds like you're braking and decelerating normally from 35 mph, then the pedal does some weird vibration at about 30 mph, then you continue braking and it's back to normal till you get down to maybe 20 mph and the brake pedal vibrates again, and smooths out again, and then you finish the stop?
Maybe your vehicle speed sensor is hooked up to the wrong wire and you're overloading that part of the ECM and it's having trouble figuring out how fast you're going. While it's confused it might be activating ABS or ATRAC or something.

When I am at any speed it does it but what I have been doing to try and diagnose it was get up to 30-35mph and take it out of gear and just coast then apply the brakes about an inch or too and keep my foot in the same spot and i get the feeling... the feeling is smooth then a bump smooth then bump and its constant so the faster i go the faster the bump comes around...
When I go to the settings on the Avic D3 head unit and click the vehicle Speed Signal Wire Test it is reading the same speed the car is traveling so I assume it is hooked up correctly..
