• The cables on my new Shimano MT401 disc brakes are not yet connected but the inserts have been installed already. I'm not going to cut these so glad to have them there already but it looks like there is a clear plug pressed into the insert. There's very little to grab onto but i'm assuming these should be pulled out at install?

  • If it's in the barb, it's likely just the plastic film/plug/bung that get's punctured when you install the hose. Pics would help though.
