That is also a symptom of rotor runout, solid brakes till the rotors move and push in the pistons. Check rotor runout for a bent or warped rotor. Tire change time is an opportunity to bend a rotor by leaning on rotor or tipping over the rim.

 

I had the exact same symptoms. Turned out to be a bent rotor.

 

Hey guys and gals. I still haven't figured out what's going good on. We lost day light and energy and needed to get the bike to a safe place. Unfortunately the only place there was a stealership nearby. Waiting for the results now. :-(

 

Well guys it was the rotors indeed. Got a new set coming in before the end of the week and should be back on the road in time for the weekend! Thank you all for your help!

 

bent/warped rotor -- had the same thing happen on my bike -- the guys who changed the tire got to purchase me a new since they damaged the old one
