My car has been sitting for like a month or so and today I went to take her for a spin and noticed some serious vibration in the brakes. The passenger rear to be exact. I did'nt drive it long to see if the vibration went away. Just wondering if anyone else had this problem. I have all new rotors and calipers and pads. Do you think the caliper could be loose? I cranked on the bolts. Should've probably used a torque wrench huh.
