A friend of mine is getting a '91 sonata for CHEAP. Just something to drive that doesn't use too much gas. The cars not actually in bad shape, but the brakes could use a little help. It has new rotors and pads in the front. The problem is, when you hit the brakes, there seems to be very little braking power. When you push it to the floor, the front right wheel will lock up, but it doesn't feel like the others are really helping out. I can't figure out why one wheel would work, and the others wouldn't. The master cylinder has to be working, right? It's really kinda scary to drive this thing as is, even with one wheel locked up the thing barely slows down. I was just wondering if anyone had experienced anything similar to this, and see what I should check for. The fluid level is fine, I haven't been able to find any leaks, and the front has been bleed.
