Rear disc brake conversion


Recommended Posts

...coax the companion flange (Ford's term) off the pinion.
It has threaded holes that will work with a common bolt-grip (steering-wheel-style) puller.
When I bought my Horrid Fate 'Pittsburg' puller...
I spent up for a used (ebay) SnapOn bar puller set, and a new OTC slide hammer set (which can also be used with its included standard-size pressure-screw; IOW same screw as the SnapOn).

On some older Honda front wheel hubs, I found it MUCH quicker to use the 4-slot frame on the lugs, but the slide hammer (hitting in BOTH directions) instead of the pressure screw. For whatever reason, that seemed to break them loose much faster than the pressure screw alone, or only hitting outward with the slide. That might be necessary for a stuck companion flange. The guy who regeared my disk swap axle said he & his son had a helluva time breaking mine loose from the pinion splines. Fortunately, I already had another flange cleaned & painted for him to use, so it didn't matter what he did to that one.

Steve, I actually used my Snap-On balancer puller with a pair of 5/16-24 X 1 1/2" Gr 8 bolts and some thick washers. I thought about the steering wheel puller, but didn't think it would be strong enough.

Here is the pinion being driven out using Ford tool T85T-4209-AH

Here is the 10 tooth pinion after removal, note the rusty area on the shaft, that is where the outer bearing was.

That's what I was referring to as a "steering-wheel-style" or "4-slot" puller.

Ok, because I have a steering wheel puller, and no way would that have gotten it apart. Remember this is a 10.25" full floating from an F350 DRW pickup and everything is bigger and heavier.

I just realized that's a yoke - not a companion flange.

This shows those bolt-grip puller holes, closer to the center:

Steve, I call it a yoke, but Ford's manuals for some reason known only to Henry I call it a companion flange. I was using their terminology.

Jim, it is internally threaded 1-18 so it screws over the end of the pinion and seats against the end of the splined area, there is also an installer that screws on the end, then has an outer section that presses the flange/yoke down against the bearing and slinger.

You don't have hydroboost on Darth, so it is just that the brakes are working correctly? Couldn't all be the big rear brakes, right?

All of the E series with the Sterling rear end use the 8 on 6.5 lug pattern. All the way to 2006 at least. They have been using discs on the rear since 99.

Also, they have the internal cable operated parking brake. Not the type that bolt to the rear of the tranny.
