I have been receiving all the components to add the additional disc to my 750 K2, some of them in not-so-good condition. Everything is apart, and the threads are full of corrosion (galvanic action, steel and aluminum) So all threads have been chased, the bracket pivot taken apart, starting to paint everything before the new piston and seal are installed. As a former auto mechanic/technician, I am fortunate to have plenty of tools. This is a full-metric tap and dye set which sure comes in handy.
