these are the hose inserts you need if you're doing a trim and bleed. I shouldn't have had to buy this since my first pair of brakes came with extra inserts, but the 2nd pair didn't.
Works with Dominion A4
Works well with my Dominion A4 from 2020.
Very well machined, perfect fit!
Worked perfectly, and great that they came in a pack of 10. Always good to have back ups
Switching my A4s to another bike and this is a must have items. Easy to install and no leaks!
