Hydroboost Conversion

[yARIC008]

Did you delete the OEM proportioning valve since all 4 wheels are disk?

As far as I know the original proportioning valve was in that spacer dealie at the master cylinder. I installed a slightly larger master cylinder that didn’t have that spacer. I installed a new proportioning valve on a custom bracket right next to the new master cylinder. The original bore size of my master cylinder was 1-1/8” and I replaced it with 1-1/4”. Pedal has less travel and works well with the hydroboost, however I might change it to a 1-3/16” soon to give a little more hydralic pressure.

I was looking at Battleborn Hydroboost, does anyone have experience with this setup?

This is a special made hydroboost booster that has all of the same mounting specs as an OEM 1987-1998 Ford pickup vacuum brake booster. It bolts in exactly like an original vacuum booster and accepts your existing master cylinder. No modification to your brake pedal is needed. These are far more...
