1963 Dodge Dart Wagon drum to disc Brakes
The most important safety system on any car. Never cut corners on safety. If your budget doesn't let you do it all at once, start with what you can do.
Make a list of what you need to do and just check it off as it gets done. Eg.. brake lines, wheel cylinders, shoes, hardware, drums, etc...
Eventually you will have a safe, trouble free system you can rely on. Safety first.
