Not all mechanics are created equal. I was lazy and brought my car into a mechanic in Miramar to change my brake pads. I don’t know why but he end up removing the brake lines. When putting it back, he messed something up and it end up leaking. Luckily I wanted to change my lines anyways. The next time I needed to change my pads, I go on one of the forums, there were step by step instructions with pictures. It took me more time to remove my tires and jack up my car than to actually replacing the pads. So, moral of the story is, DIY on maintenance is always better if you take the time to read the instruction and are at least a little bit handy.
