Am seeing that when I apply brakes, the steering wheel vibrates a lot. Also since few weeks I am seeing Brake signal appearing. So I went to Midas to get an estimate and they gave it as close to $800. Am very new to car repairs so wanted to get an idea. Can someone please tell me if this is too much or OK. Midas told me that they will be changing rotors and brakes pads on both front and rear. Thanks in advance !
