I had to replace my original MC because the seals were shot. I bought a new, not rebuilt Cardone unit, hoping it would be good because, well, its new. Anyhow, I put a DRM bias spring in it on the bench, bench bled it, and put it on the car. I had the bias spring on the original MC with no problems.

From the second I put it on the car I have quite a bit of fluid coming out from the cap on both reservoirs. Could I have installed the bias spring incorrectly?
