WARNING: This is not a do-it-yourself build!
Depending on the car-you can buy a pre-made set that are DOT approved. It is very important that you use these if the the car is a street driven/daily driver. Otherwise, you risk NOT passing your state's inspection for one thing. Another reason is that the Goodridge and Russell lines have been properly tested and certified for each application. Do not attempt to plumb a brake system on your own-there is a considerable amount of engineering involved to make them as safe as possible.
