Hmmwv proportioning valve question

Pstyckiewicz · Jan 26, 2025

I have an M1152A1 that brakes fine when it’s dry out but add a little snow then the back end seems to slide out way earlier that expected.
Is there a way to adjust the proportioning valve or should I just leave it alone.

Yea... Load the back end up with 12... one hundred pound bags of sand.

No slipping with sand, CAMO

these were set up to have weight in them, and as far as I know there isn't any way to adjust the braking.

Depending on model, 1200 lbs is a good start. Mine likes around 2500 lbs a little better (m1123 with heavy suspension)

You could install a remote stand alone proportioning valve to the rear brakes with an adjustable knob and makes everything very easy. Have done this on equipment over the years.

Haha I figured it was setup to have a bunch of weight in the back. I’ll have to loader up with some sand

Definitly like the idea of adding an adjustment

A little more digging and I found something in the brake system called a brake pressure regulator. A quick google of what that is and it states that it is a proportioning valve. So my question now is where would I put the adjustable valve?
