[Closed] Shimano wandering bitepoint solved

Also, if leaks from the master cylinder due to wear was the main problem, using lower viscosity fluid would make it worse, not better. If the OP's post is to be believed, lower viscosity fluid helps. Therefore, the Red Panda kit isn't the solution.

Guide RSC’s (second hand) with the Bleeding Edge port and was expecting a bit of a tussle but they were an absolute doddle. Proper easy.

Let me guess, there's no wandering bite point? And in a few months or a year's time there'll still be no air inside? Come on Shimano, it can't be that difficult!
