for my project im building, im going from a 95 camaro with drum brake rear to a LT1 posi disk rear. i have all the parts, and ive researched but i cannot find any info on what needs to be changed up front? i know the masters and boosters are all the same, but shouldnt there be a difference in regulation between drum and disk? is the abs/distribution block the same? or do i have to change it? just need to know what i need to make this swap 100% proper

 

I would remove the guts of the stock proportioning valve and install an adjustable one.

PM me and I'll tell ya how

 

pm'd anyone else got any input?

 

I've done the conversion to my 96 and only changed the calipers etc. in the rear. It works fine without changing anything up front, but the guy who did the work said if it didn't seem right that I night want to replace the proportioning valve. So I'd say look into that if you want.
