What is the noise from the bottom rear when entering and exiting the vehicle?

What is your question?

My Fit was a brand new car, currently has 34,108 miles on it. I had a mobile brake job yesterday afternoon where the technician came and jacked up the car. He ended up just cleaned the front brake pads and the brake shoes, saying that it was very dirty, and ensure the noise would be gone. He then tested drive my car; the rear tires had abnormal noise (sound who-whoo) when he brakes, he then jacked up the vehicle again and used a flat to tighten up the shoes (he pressed down the little metal part for 23-26 times, then he turned the circular metal to feel the tightness. He told me the job was called axle cleaning/shoe adjustments, charged me $79. I didn’t move my car at all, but when I came out from work, I noticed that there is loud noise (wreak-wreak) from the bottom rear - it sounds like a 600lb-person sitting in the car, pressing down, and the vehicle can’t stand the weight… I’m super worried about the noise. Can anyone help?What is wrong with my car? Thank you in advance!

What makes this problem better or worse?
