I was researching a rear disc / full floater swap.
I was not enamored with the rumors that the "supra" parking brake didn't really hold the truck well.
The flipped over bleeder screw thing wasn't making me thrilled either.

The Wildwood Combination Proportioning Valve looked like I could readily install it under the hood.

There is a mounting bracket that might need to be modded a bit to work with a Toyota MC
Wildwood makes a LEFT and a RIGHT sided bracket

I was also planning on the 1" MC upgrade

And or course the 86 Turbo 4Runner Dual Diagram brake booster...

and then the Full Floater Axle with the Rotor upgrade

So - the question is
a) any one using that Wildwood prop valve?
b) any one running that DRotor (4Runner disc / drum parking) conversion>

 

I never used that model not needing to restrict the front flow.

Put a single stage one to adjust fluid to the rear for a person that just had to have one

Learning to drive without any Valves you just got used to the braking of the vehicle

The Toyota`s on the road I drive the LSPV`s were removed first brake job

 

I run no rear valves aswell. Braking is better i find. Thats with stock drums though....

 

That proportion valve will require more pumping than a single circuit one. I'm currently doing disc convertion. Trail tough's kit and adding a line lock. I'm using Jeg's line lock, several jeeper guys had reviewed it good for trail stops which is my intended use. So yes I'm loosing emergency brake, but that has only intermittenly worked since i've owned the truck.

Looks like a solid set up but spendy. You can also use the V6 dual diaphragm brake booster without issue. Atleast I had no issue and been using it for years.

The FROR kit is choice, have read mixed reviews about parking brake so may be a matter of installer and parts used.
