Re: DO NOT TRUST BTV

I don't know if anyone has considered those particular items or not. The ones pictured appear to be firewall mounts and aside from having brackets ready made would still have the same issue of not being able to go in the original spot or use the original pedal ratio. They might be an option if someone is considering a firewall installation. The common US suppliers -- ABS and Master Power Brake -- that seem to get most of the Packard retrofit business probably have them too. As they are assemblies and would still require some ingenuity believe most just opt for the individual piece and universal equivalents and go their own way with brackets and/or pedal mods.

That VW master that resurrected this thread is intriguing and really would like to see someone test it to see what it is capable of doing with the original pedal and no vacuum to the power assist. If the originator of the mod won't be able to do it anytime soon, maybe someone contemplating doing the current mod requiring the pedal change would be willing to spend a bit extra and try this first. Not sure how much the adapter piece would cost but the extra for the VW master and fittings is not much. Anything else bought and any mods made could still be used if it turned out to be problematic. If you still wanted to go with the known mod with dual master and the pedal change it would just require a different master, a few more fittings and a bit more time to do the pedal mods. If the VW cylinder worked satisfactorily in the original spot it would likely be adopted by many.

Will admit I have my concerns if it will work with the low pedal ratio so until proven it can at least slow down the car as well as a BTV with no power, it is just one of the many ideas. Since ABS recommends a higher ratio, I am more concerned about those Electroboost units installed with original pedals. We all know BTVs with no assist are not spectacular when it comes to stopping a Packard and I have my suspicions that those with the ELectroBoost with large diameter masters and low pedal ratios will find almost the same result as a complete BTV failure if something happened to the boost portion.
