Now calipers have been cleaned & sand blasted, work can begin separating & evaluating the assemblies. Rear calipers were fist split removing the 4 bolts followed by the retaining bolt for parking brake clamp arms. Next was the handbrake lever pin. Removal of this required drilling & extracting the split pin fitted. Attempt then made to extract pin, however, pin was severely seized requiring heating & pressing to extract. Once removed, the caliper assemblies could be seperated in two. Both pins & lever arms appear distorted & will require re shaping or replacement. Removal of the pistons was next. The pistons of which were found to be severely seized also. Outer gators were removed & exposed edge was cleaned of any left over rubber. Penetrative solution was then allowed to soak before heating the outer casing of the caliper. An additional solution was then used to cool & shrink the piston within the caliper. Vive grips could then be used to slowly work the pistons until eventually free. At this stage, both rear calipers are stripped aside from the larger piston witch is yet to be extracted
