Blocked brake proportional valve

[BARWICK]

Hi guys,
just completed a drum to disc conversion on the rear of my ae86 and im trying to bleed my rear brakes with no success. Ive worked out that the JDM AE86 brake proportional valve i just puchaced is blocked.

Does anyone have any solutions on clearing out/repairing this valve?

Kind regards

Correct me if im wrong but doesn't the drum brake proportional section have a valve in it, and the disk brake has nothing inside it.

I would dare say an overnight soak in petrol would clean almost anything.

You can pull it apart (unscrew the brass fittings) and clean out any junk inside.

Also it is rumoured that the ADM bias valve can be modified to suit rear discs by removing/shortening one of the internal springs.
