Dominion K2 Hydraulic Hose Kit

Everything needed to replace brake line. All necessary hardware included. If you reuse any of the original hardware the new parts can be saved as spares.

I used this to swap an A2 front brake to be a rear brake. I was able to reuse the old banjo bolt and seals so now have extras of those because this kit includes that hardware. Bleeding was quick and easy. Use a bleed cup on the lever and leave it open when reinstalling the caliper bleed screw to minimize air ingress. 10/10 would buy again.

Comes with everything needed to swap the brake hose on A4/A2. The hose is thicker than comparable SRAM/Shimano hoses, so fitment on internally routed frames can be more difficult if the openings are not wide enough.
