Today I started to investigate a potential rear seal leak on my cool hub system. After taking my tire off I noticed the Caliper Body Assembly was very loose.. but, the bolts were tight.. after taking everything apart and inspecting it all seemed ok.. pads had a little uneven wear - pads more worn on bottom half then top.. once put back together the caliper body was still loose and would move around rather freely. Caliper is tight and pads are firmly in place..
Any ideas?
