Latley, I've been noticing that my braking has been very uneven, particularly at high speeds. The car shakes slightly, and I can feel the brakes catch a little harder every now and then. I brought my car to the Acura dealer to get it checked out, and they said that my rotors need to be machined. Is this a likely cause for the uneven breaking? Is it worth getting fixed right away? My car only has ~39,000 miles on it... seems like a weird thing to go wrong this soon.
