I took my car in to get my brakes fixed because they were squeaking. The guy told me I didn't need new brake pads but I just needed them "deglazed" well that was 100$ and they squeak worse than ever!!!! I took it back and he said he would re do it but if it still doesn't work I would have to buy new brake pads! So that original 100 I spent just went down the drain! My boyfriend told me what deglazing meant and it's like spraying a coat on there. And I got worked! They were just taking advantage of me because I'm female like most audio places do!
