The main reason people have problems with brake balance is because they don't check the pressure at the wheels with a gauge.... Setting brake pressure by feel is like guessing at water temp by touch!!!!!!

Another reason I'm such a big 9" fan is the ease of changing gears...Just have your spare center section set up with your alternate gear choice.....

Another good item that just came out for braking systems is a junction block, proportioning valve and brake light switch all combined in one unit...Wilwood sells it, decent price, too.

Disc brakes front and rear, when sized, set up, and pressure balanced correctly offer a huge increase in stopping power over drum or drum/disc setups!!!
