Hey guys... I just was looking over the car (79 racecar) ... and I noticed that my "factory" brake bias is still on the car. (ok)... However I also have a manual adjustment inside the car......

My question is do I need to eleminate the one on the master cylinder in order to get a true adjustment inside the car....

 

Take the valve out of the factory proportioning valve and test it out that way. Saves having to redo the brake lines.
