The problem really is a "chain of events" 1.st The cover for the E-brake has cracks, this 2.ndly leads to moisture enterring the area where the axle enters the brake caliper, 3.rdly this causes the axle to corrode as the picture shows. 4.th the corroded axle "chews" the O-ring and causes the caliper to leak.
