<prompt> Human: Hi,Not sure to post specifically but hoping some folks here can help as I see a lot of financial conundrums answered. My girlfriends cars brakes were making a slight sound this week. Sounded like it needed new brake pads, probably only 1 corner was close to wearing out. She has a trip this weekend so took it to the dealer to get it done quickly. She got a quote this morning of over 3000. Theyve told her they need to replace all 4 rotors and calipers and also her rear brakes are shot... which makes no sense as the rotors and calipers ARE the brakes.. so what else are they doing on the rear?I know a little about cars and often swap pads on my own car, total job is about 30. I expected the dealer to use expensive parts plus labor to be about 100 but this is nuts.What should I do here? I know theyll have excuses as to why all those parts need changing but its excessive to me. Rotors dont realistically wear like brake pads and a single caliper needing replacement suggests a serious problem, let alone all 4... the car would have been a death trap its not, its only a couple of years old. I feel they saw a young woman come in by herself and knew they could say anything. Shes now afraid of saying anything about it as they insisted to her this was all necessary. I think they saw someone they thought they could take advantage of. What, if anything can I do about this? Edit: Thanks for some follow up. I do understand all parts can need replacement. However Im experienced with cars and mechanics. She only noticed the sound this week and was worried, she also needs the car for a trip this weekend so needed it ASAP so wanted to take it to her regular mechanic at the dealership. Ive never been to him. I think shes been taken for a ride as I dont believe what she was told to be true. Also what they told her they are replacing doesnt make sense The caliper, the rotors, the pads oh and also the brakes need changing... Um, what?  <response>: Take the car to another mechanic.
