Ok, Here we go. I replaced the single brake master cylinder with a dual brake master cylinder. I also replaced the wheel cylinders, brake lines, hoses, springs, everything. So, I know I have drum front and rear brakes.My question is, do I need a proportioning valve? I haven't found any information on a Drum/Drum, needing a proportioning valve. If it was disc/drum then yes, you need a Proportioning valve. Help!!! If I drive down the road, And hit the brakes like in a panic mode. The rear end locks up. The front, not so much. The truck has a 235 and My new 410 gears in the rear end. I can get up to 60 miles an hour. I should probably convert to disc front brakes.



What do y'all think?
