Rear Brake Proportion Valve

Does anybody know if there is a way to adjust the brake proportion valve? Is there even on present on the 2nd gen or is all controlled via some computer?

I recently purchased my SAS'd DCab and had to slam on brakes today. The fronts did not lock up but the rear did. I was still able to control the stop although I am sure it looked scary from behind.

I am hoping to take some of the hydraulic pressure from the rear and keep it towards the front.

 

Buy a wilwood porportioning valve and plumb it in the rear line

 

thanks for the advice

 

We have a brake line for each wheel which means I would need two of them correct? One per wheel and then adjust as necessary...

 

Nah just Tee the two separate lines to one, then porportioning valve and cap the unused line

 

Since it's already solid swapped it's easy to get rid of the abs module
