I'm driving a '12 VW Scirocco. Last Friday I had my winter tires put on at the shop, and I went for a 700 km road trip here in Norway. After some 100 kilometers I noticed my car making a cluncking/thumping sound as I applied brake pressure, and I also noticed pulsation in my brake pedal. The problem seems to have worsened over time. The pulsation and sound follows the rotation of the weel – ie. at high speeds the pulsation is more frequent than at low speeds.
I immediately suspected a warped rotor, but I am not sure how to resolve the problem. Do I have to take my car back to the shop and pay them a lot of money to get this fixed, or do you have any suggestions as to steps I can take myself to resolve the problem?
Thanks in advance.
