***I have searched a lot of threads, I have seen a lot of different resolutions; however, everyone has a different combination of parts. I know there are a million ways to do this, but I am seeking everyones input.***
I have a 1968 FJ40:
- '76 disc front axle with 88 4 runner calipers ( they have the 4x 40mm pistons) I believe.
- On the rear I have my stock '68 axle with the monte carlo Disc conversion kit.
- Single diaphragm mini truck style booster and an 80-Series Landcruiser Master Cylinder
-Willwood adjustable Proportioning Valve
I have the common problem that my back brakes are getting too much pressure and locking up the rear brakes... I have adjusted the proportioning valve in every combination (to ensure I was in fact doing it correctly). I have also confirmed that my brake lines are plumbed correctly.
Should i just add an additional proportioning valve in the rear? Like This?
Any help would be appreciated, I was under the impression that this configuration would work. All parts were new or rebuilt (out of the box) when installed. It is pretty close, it is really only most noticeable on Low traction surfaces (wet, sandy, gravel covered pavement, or gravel or snow)
