How do these work exactly? It sounds as if the brake system can subtract from the front brakes and apply a higher percentage of pressure to the rear to keep the H2 level.


Standard brakes apply 60% towards the front and 40% to the rear. If there is "Dynamic Rear Proportioning" brakes, what would the percentages be if maximum were applied to the rear and minimum to the front?

a valve hooked up to the suspension moderates the brakes as per the squat in the suspension...more squat=more load=more rear brake action...

That just doesn't sound right to me. If you apply more braking to just the rear, it's not going to make it more level unless you take some from the front as well.

Hi Tomp,

Hope you getting that Carbon Kit installed.
I think at this web site you might get some insight:

Ranger, that link addresses mechanical brake bias and tomp is referring to the electronic version our H2s use.

Dynamic Proportioning in late cars is a product of the ABS system. Some vehicles used to utilize a hydraulic system but ours and most others that claim "Dynamic Brake Proportioning" is fully electronic and it's tied to the wheel spin. It uses software algorithms to determine the differences between the wheel speeds upon braking and to dynamically change braking at each wheel, regardless of the load in or behind the truck.

Thanks Paragon,

The second to last para discussed the issue you speak of (Dynamic Rear Proportioning (DRP), Electronic Brake force Distribution (EBD), and algorithms.

Thanks again,

That link did shed some light on how RDP brakes work and confirms what Paragon stated. Thanks to both of you!
