I needed to replace a cracked rotor on the buggy and after researching rotors that I would not have to redrill to 8-6.5", I come up with this.
I use a set of 99-04 Ford Superduty outers on the 609 in the buggy. The Superduty brakes are very good at locking up the tires almost too good. Hydroboost and matching Superduty master cylinder. I wanted to have a lighter simpler brake setup with plans to use for years to come.
Parts needed.
Rear rotors: from a 2002 E-350 club van. They have a 8-6.5" pattern not the metric 8-170mm pattern. They do need a little machine work to open up the rotor hub register to 5.085" This could be done with a grinder if needed. The wheel studs could also be removed and the unit bearing machined to allow the rotor to slip on as well.
Front calipers and pads: from a 1977 GM C-20 pickup. This is the same caliper used for rear full float disc conversion.
Then you need to fabricate a simple bracket to mount the steering knuckle. Then drill and tap a couple holes to mount the caliper to.
The new rotor, caliper combonation saved 15 lbs per side or 30lbs from the front axle.
Additional benefit is lower cost of replacement brake parts and having matching calipers front and rear.
Hopefully we will see some vendors start making their version of the bracket to allow a bolt on kit for these axles.
