Ive Code RSC (Came on 2018 bike) and they havent been ridden much in last year. Just been to shed and found the front brake rubbing, no more bite point adjust left so pushed pads back a little. Now lever wont return. No fluid leaks that I can see.

Anyone had this or similar?

Thought Guide lever was the same but apparently not although are internals the same?

Seems quite a common issue on Guides and you just replace the lever piston which Im fine doing (Changed Elixir lever internals on several occasions!).

Anyone know the part number required for 2018 Code RSC brakes?
