When the 5 speed hatchback is in reverse, there is a squeaking sound. Also there is a squeaking sound occasionally after driving for about 20 minutes. I am getting the brakes looked out, and think I need pads and probably rotors. Need to know what to expect when I go in to the brake shop, or should I go to a larger shop who can work on more? Also- I have replaced the cv boots twice before, my mechanic never could tell me why. PS- I don't have a local mechanic at this time and of course am short changed. What to do? Thanks for any advice.
