On my 2014 Tri-Glide, I am having a difficult time getting the left rear wheel caliper piston to recess and seat inside its caliper housing. As mentioned to me in an earlier inquiry, I do not see two (2) holes or indentions in the piston's front facing surface area, so I don't think the piston has to be first turned "clock-wise" to recess into the caliper housing. In turn, as a possibility, I am considering the use of a "C" clamp to recess and seat the rear caliper piston. Has anyone used a "C" clamp to recess/seat the rear wheel caliper piston(s) when replacing their Trike's disc rotor(s) and brake pads or is the use of a "C" clamp a definite "NO-NO". I would appreciate and look forward to receiving your responses. Thank you, Allen S.
