Hi all! Hope for input on this. Just purchased A4 Avant Wagon. Was told it had a frozen caliper front passenger side. I replaced the caliper no problem however this did not correct the issue. After a short period of driving. you can start to feel the drag and shortly after that it starts to shutter feeling like from the passenger side? Both front rotors are HOT to the touch and the rears are cold? This is A DYI project and any input would appreciated. Thanks!!
