oh! that would do it then lol

whilst I am wait for the brake grease to arrive I thought I would possibly change the rubber sealing boots on the sliders although they seem ok i.e. no splits etc, Question is do Honda make a standard slider boot? or are they like all thing 24 only made for the NC24 model (groan), I checked Out David Silvers and Wemoto but they seem to only stock replacement rubbers for the rear brake, i suppose that leaves only Lings as a possible stockist.

correct me if I am wrong but are the part No.'s 45132-166-016 and 45133-MA-006

Your part numbers are correct; I'm getting some (for my NC21) from CMSNL as part of a bigger order. They cost 2.5 Euro and 3.5 Euro respectively.
