fullmoonflyer Posted December 17, 2005 Share Posted December 17, 2005 Howdy- I have most of the parts ( I think) for the drum-to-disc conversion on my EA-81 Hatch. My big question to you folks that have done it before: Is it necessary to change out the brake proportioning valve? Where the heck IS that valve located? I looked all over my hatch & couldn't find one, nor could I find any reference to one in either the "How to keep your Subie alive for the compleat idiot" nor in the Haynes manual covering 80>88's. I found reference to the proportioning valve in the Hayne's covering 80>94 stuff, but it was nebulous on the specific location of the alleged valve. I got my parts out of a 87 turbo wagon with manual trans. Does the master cylinder/hill holder system need to be changed out as well? I would greatly appreciate some experienced advice here.

bratsrus1 Posted December 17, 2005 Share Posted December 17, 2005 Hey Fullmoon This is Jerry, no you don't need to change that valve. I am the first person that done this swap over that i know of. It is very simple mod to do. Just unbolt the rear brakes and bolt the rear disc on and blead the brakes your done. Thanks Jerry Link to comment Share on other sites More sharing options...
