What tools do I need to fix my brakes

If you don't know what tools you need, or if you don't have them, and you have never done mechanical repairs, before, I would suggest that you take it to a mechanic.

You would need to dissassemble the wheel hub, while the car is jacked up. You would need quite a few expensive tools. It can also go horribly wrong if it isn't done right. I don't know what the problem is with the brakes, but I would suggest that you don't do it. If the brake isn't perfectly aligned, you could have a loss of braking power on that wheel and end up swerving when you brake, you could wear out your brake pads, there's many ways it can go wrong.

Let me know if this answers your question!
