Re: BTV replacement

Hi Fred,

The pullers I broke, one was a normal flimsy 3 prong bearing type puller hooked up to a home made flange bolted on with the wheel bolts, the 3 prongs on this just bent open. Next I used a purpose made hub puller the type with 3 lugs on one side and one opposite designed for 4 or 5 bolt hubs with a square thread bolt running through pushing against the shaft, the lugs on this cast body snapped...
I realize I need a hammer type with jarring action to shock the tapered hubs off as shown in the Packard service manual, my only concern being while hammering, the turning motion is surely only being stopped by the parking pawl in the twin Ultramatic, is there any chance of breaking this instead of the hubs coming loose..? I also couldn't find one of this type.

The brake set up I now have installed is a manual master cylinder hooked up to a remote mounted 3:1 ratio vacuum booster mounted in the inner fender above the vacuum tank which I lowered slightly from it's original position. The brakes are still single circuit as with the BTV though all components are now new and I don't think there is as much chance of failure with the components used as with the BTV.

As for pedal position, my brain is now accustomed as to where it is and I would still rely on this more than stomping down on a BTV only to find my foot on the boards some day. I wanted to use the original pedal to keep the look original but that wasn't to be so I did what I could copying someone else's design that works.
