So I’ve deleted my ABS system and I’m trying to dial in my new proportioning valve.
My new brake system consists of the original vacuum booster and master cylinder with 3/16 braided stainless lines to a Wilwood adjustable p-valve.
Front brakes are braided stainless 3/16 lines from the p-valve to the factory 3/16 hard lines on the frame. Calipers and everything at the wheel is factory.
The rear brakes are a braided stainless 3/16 line to a 10lb residual valve to the factory 1/4 hard line on the frame. Everything from the rear hard line back is factory.
The brake pedal feels firm and great and the brakes work great in normal operation but the rears lock up a little still if I completely stand on the brake pedal, even with the p-valve turned all the way out (less rear brake). Nothing dramatic, but it seems odd.
Is this a sign that the front brakes aren’t getting enough pressure, or that the rears are somehow still getting too much or normal for a truck without ABS.
All in all, it’s waaaaay better than the twitchy ABS locking up the rears constantly.
