Took my CL into the shop to install my Wilwood BBK finally, and one of the calipers is not working properly. The two outer piston are retracted and don't seem to move (like they are seized). I have had them for six months at home and bought them on acurazine of a member not sure how long he had them for. They are brand new never been installed so... Just looking for some help on the issue if anyone has had this happen to them. My mechanic seems to think there is a problem with the caliper internally (the chamber inside where the fluid channels).
