SignUp Now!Proportioning valve will only change where the fluid goes to it won't change how much fluid the master cylinder pushes out. With larger calipers and more Pistons more fluid is required to push them. I was wondering about maybe a 4x4 tacomas master cylinder swap but am not sure on fitment or if the bore is larger since the calipers are 4pistons. I have been looking into The swap because I would really like to do a rear disc setup with my 360mm front bbk the stock master can't push enough fluid so I have not went that route yet. I have seen on a few other sites ppl swapping out their master for one with a bigger bore but it was all 4x4 guys and usually older tacomas. Def will be keeping a close eye on this thread.
Thanks for the info. I have heard about a lot of the older trucks and getting swaps but I was not really sure with how our clutch is setup as well. I have never personally done a master cylinder swap so if anyone does one and has good results with a write up I wouldn't have a problem trying it myself.
Hate to dig up a somewhat old thread but has anyone tried doing this with success?
