3/16 going to the front is a smaller line then 1/4 or 4/16 going to the back. If Discs take more fluid to opperate, then that meams more fluid would move farther in a smaller line then a bigger one. Fluid only moves if it has some place to go. If one side of a wheel cyl is froozen up, the brakes will only wear on one shoe and will not on the one side that is froozen up. That happened to me. I needed to replace the wheel cyl all the bolts broke off. The 2 mounting ones, the bleeder and the line bolt stripped.
I will be replacing with a dual 7 in power brake booster and replacing all my lines. I have a 53 long box truck with a newer 14 bolt 3.75 ratio rear end. I do not know what size my lines are at the master cyl, or what size I should use on the rear end etc etc. Also I want to change from the right side to the left going to the back and change the mounting braket to the flexable like to the rear end. Has Any one done this to there truck? Let me know.
