Height Sensing Porportioning Valve
On my 88 Dakota 3.9L 4Wheel Drive I have a brake valve that senses the
load in the bed. The valve controls fluid to the rear brakes by
sensing if the truck is squating from weight.
The problem being that I have no brakes on the rear, plenty of braking
power in the front.
The fluid path is as follows:
Master cylinder to the Combination Differental and metering valve.
It splits off from this valve to the front brake cailpers.
It also splits off to the rear brakes and goes to the height Sensing
Valve. From this valve it goes to a tee where it splits off to both
rear wheel cylinders.
When I bleed the rear brakes I get very little fluid from the rear
bleeder screws. No air bubbles and very little fluid flow. I think
this valve may be bad and at 156 dollars I don't want to do a parts
changing operation to determine if its bad or not.
Question:
Can I by pass this valve by connecting it directly up to the
Combination Differential and metering valve? Is this a bad thing to
do? I know that I will have to plug the bypass port on combination
valve but am not sure if the system will work right with the height
sensing valve removed. Any thoughts?
I could run a pressure test if I had the gauges. Any sugestions on a
good gauge set for testing pressure in brakes systems?
