I tried to flush my brake system in my car. I tried to watch a couple of UTubes but they were long winded and I got bored. Dumb. I was originally changing fluid because the brake pedal had gotten really hard to press and was getting worse. I flushed system best I could. Now I have NO brakes at all. After going back and watching vids I now no I shouldn’t have done it by myself, and a couple of other things I did wrong also. I don’t have anyone to help me. I refuse to pay anyone to do it cause I want to learn. Can anyone tell me if a affordable (100$ or less) vacuum pump will work? If u look up mityvac and a few others there is always bad reviews. Thanks
