brake proportioning valve

[ginericLC]

My friend's internet is down. He called me tonight and asked me what the thread and pitch was of the proportioning valve. I didn't know off hand but that brings me to another question.

He is driving a 91 FJ80 that he installed my old 94 rear axle in. So he went from drums to discs. The factory LSPV was not working for him at all so he removed it completely. His brakes work great now but of course the rear wants to lock up first. Anyone know of a factory Toyota part that would have an adjustable proportioning valve. I was thinking an older Supra might have what he needs. Maybe a newer Celica? any ideas? Or should he just be looking at buying an aftermarket adjustable one from Summit or ???

Any and all suggestions that lead to a solution are greatly appreciated.

gineric,
I am interested in what you find out. I have been thinking about doing an axle swap myself. I was wondering if there would be any ill effects.

Find one from a '93+, or use the manually adjusted summit type.

There's no way I would go to the stock piece...

Get a manually adjustable one from Summit or similar place and adjust it so the rear wheels lock up just after the front on a gravel road.

I do believe he is going the Summit route now. But there are a lot of fittings to convert it to work with the Cruiser lines. That is what he was trying to avoid.

Get a flare tool and new fittings, cut off the toyota fittings and put on some standard ones.

Summit sells the Tilton 7 position adjustable in metric for around 90USD. Napa sells any adapters lines (M10 x1 to M12 x1) if needed. I installed these in my 4R and several in the metric audis I work on. The only issue with the routing of the lines in the toyotas I've found is that there is an overrun feedback to the front lines, requiring an extra T fitting. The toyota dealer can source these for under 20USD with a mounting bracket attached, btdt.
