Reading through some catalogs from last years SEMA show I noticed that EBC brakes says that the Harley Davidson SuperDuty came with 14.5 front rotors stock and 13.5 rear.

Looking at replacing brakes on the excursion and if I can do a factory big brake kit for less than everyone else pre made kits why not right?

I am thinking at most I should only have to have new Caliper brackets made. Unless there is more that I do not know about. Also looking into SSBC calipers I just don't know if i truely need 6 or 8 piston calipers. I already have an exhaust brake to install and soon will have an exhaust brake function on my tune for the turbo.

Just throwing out ideas

I'm also interested in this.

 

well I found that you have to change out the knuckle for a 2005-7 style knuckle if you want to use the factor calipers. New they are $300-$400. Looking for a nice used set up at the scrap yard. We will see how this goes.

Looking at a 2005 axle swap too so now its time to break out the calculator. lol

How are you doing the exhaust brake? I've always read that's a terrible idea on these. That may only be for the 7.3 though, not 6.0.

 

I am new to powerstrokes but if you can use your turbo as an exhaust brake why couldn't you use a regular exhaust brake especially if you switch to a fixed position turbo? Should be the same thing. I wouldn't run both. It's depends on what my needs are. Typically a locking torque converter and head studs are all that you should need for an effective exhaust brake.

If there is some other flaw, I'd like to know too.

 

If you go to something like a Powermax turbo, you'll need a setup like BD sells for about $1300 which is the true exhaust brake. You won't need head studs as the back pressure on these is only about 40 lbs. Since you'll already have a tuner because of the Powermax, you can have your writer mod the tune to keep the converter locked in all the way down to about 1100 RPM.

Or, Banks sells a pod you plug in that does it all with the VGT turbo. Closes the vanes on the stock turbo, locks the converter. Seen them work, and they do a nice job. Not as effective as a traditional set up though.
