Navy, a little confusing here, you said no piston advancement but then it moved out and back in? Just trying to figure out if its "#2 - The sprag will seize on the inside of the piston and will never work again" or what. I still say swap a front & rear caliper which would check your master cylinder as well as valving, about 15-20 minutes should tell something then. Just really curious at this point.

I thought that might be confusing. When the e-brake is applied it pushes the piston out but retracts without adjusting the brake when released. The sprag seems to only work with a full throw of the e-arm on the caliper, that can only happen when the caliper is off the rotor or a pad is removed.
