Doing a full brake service including new seals and pistons in the calipers and replacing the master cylinders. Upon removing the existing master cylinders, I found that the front and rear MCs were reversed. Meaning, the rear MC I pulled out was the 7/10 and the front was the 3/4, instead of vice versa.
I am ready to replace these and put the correct ones in the correct places, but this puzzles me since the brake bias should have been really messed up and I am wondering if there is any reason why I would just leave things in the current configuration since it apparently works and the brake bias measurements were ok.
Does the proportioning knob have enough control to reverse the inherent bias of the MCs? In that case, it wouldn't matter how you installed the MCs, so that doesn't seem right either.
Another possibility is that the brake pressure transducers were also reversed, but in that case, I would have been running with a rear biased brake and I am sure that was not the case.
