Got all the parts together to change over from vacuum assisted brakes to hydraulic but have one small issue. The vacuum brake sensor throws the service brake engine message on DIC everytime you start it. Anybody got any ideas to make computer think its good so it quits throing messge everytime? It has 3 wires going to the sensor a grey, a orange aqnd a yellow w/black stripe.

 

Maybe have someone flash it with a tech II?

 

If it can't be tuned out you may have to try running a vacuum tube from the intake with an inline check valve. There are several of us here wanting to do this upgrade at some point so any pics and reviews you can post will be much appreciated!

 

Man, i'd be scared if my brakes stopped me any faster! My brakes are amazing!
Isn't that another perk of getting the 6.2L is the extra large brakes?

 

Get a cam and all that changes. My cam killed my vac.

 

How big is your cam? Do you have a 5.3?

I have had cams in the 23x range before in 5.7s and had no vacuum issues at all.

 

4 wheel discs were definetely on my "want list" along with the 6.2

I can see bigger rotors and powdercoated calipers in my future....

 

Trust me, I pray each time I hit the brakes, after the cam swap.

 

Just thinking out loud here BUT....


Old school drag racer method of Vacuum canister OR some sort of electric vacuum pump any sort of workable option? Or is it just not worth messing with and youre better off going hydraboost? Ive had several Dodge Diesels in the past and I gotta say I was spoiled with the hydraboost brakes by comparison...
Like THIS but cheaper(obviously)

Belt driven vacuum pump off a cummins (designed for the "jake" exhaust brake) would also be a great option if it wasnt so expensive
