Anyone using a brake bias spring?
I have a DRM brake bias spring waiting to be installed. It supposedly makes the rear brakes do a little more work resulting in shorter braking distances. Is anyone running this mod and did it make a difference?? :confused:

I am running it and from what I can tell it keeps the rear of the car down under extreme braking. I believe it does this by increasing the braking to the rear slightly. I am happy with it. I installed it myself and then bled the brakes afterward.

I have the same spring. Installed it myself and had a track event the same weekend. Made a difference as I found I could brake somewhat deeper and the car dove less. Cheap mod and easy install. :yesnod:

Re: Anyone using a brake bias spring? (turboo2u)
Yup, been running one for a while and installed a couple of friends cars. Good mod, worth the money far and away. When I went to performance brakes, the stock pads on the front were half gone and the rear were like new, there was no wear at all on the rear pads. Now the front and rear wear almost dead even! Just be careful with that Brass Block and Aluminum cap. I take the block out of the car wrap it in a towel and put it in the vise, gently. Of course don't forget to plug the lines so they don't leak. Bleed the system. they are right it really reduces nose dive and you can brake a lot later going into the turns.

Any guess as to what the brake bias % is stock...front to rear?? 70/30?
Also, what is it after changing the spring???? :confused:

Mallett has them... and I think the 2000 and above do not need them. (then again I dont get paid to think here... so I could be wrong) ;)

Re: Anyone using a brake bias spring? (Operations)
I think it is the 2001 and up that cannot use the brake bias springs as I think these are the first to get electronic brake distribution. The EBD also changed the brake bleed sequence.
We need someone good at knowing what features were introduced when.

Hate to sound goofy but where do you get one. And are there some year models that do not need them?
Thanks

Dynamic Rear Proprtioning (DRP) is described in the 2001 service manual. I Don't know if the 2000's had it.
From page 5-206:
The dynamic rear proportioning (DRP) is a control system that replaces the hydraulic proportioning function of the mechanical proportioning valve in the base brake system... The DRP uses active control with existing ABS in order to regulate the vehicle's rear brake pressure.
