AE86 proportional valves (brakes n shizno)

[rthy]

Update: All of my assumption are incorrect. See Jonny's post on the 2nd page

Due to the lack of proportional valve stock at toyota... whats the difference between the rear drums and disk proportional valves?
besides the drums has a single piece proportional valve and disk two piece?
is there a way to modify the drum propvavle to work with disks the same way as the disk propvavle?

the reason why i ask is that the drum wheel cylinders require more liquid for the shoes to hit the drums... so when swaping over to a disk rear end the rear brakes force will be stronger than the front.

i did look around on the internets but didnt find anything solid with modding to the drum pv to use on disks rear ends.


edit: this is for drum to disk rear end, factory swap over
Using the Factory ADM PV can you modify it to use disk rear end?
not after adjustable/aftermarket pv as i would have got one along time ago.
