Now it’s time to install the barb. Our SRAM barb
comes with a handy threaded piece that can be
screwed into the hose using a T10 Torx fitting. If
you’re using Shimano or another brake brand, the
barb may need to be hammered in.
The barb must be fully inserted into the brake line to ensure the hose will hold
in place under high pressure (when you really need the brakes to work!). Be
sure the head of the barb is mounted flush with the end of the brake hose.
Now, with the fitting kit fully in place, it’s time to insert the hose into the brake
lever. If you’ve done this quickly, you will not have lost much, if any, fluid.
Push the hose all the way in until the barb bottoms out on the
inside of the lever. This is where it will be compressed into place
with the compression nut.
Now, while holding the line in place fully inserted, thread the
compression nut into place until it begins to snug. This is a terrible
nut to cross-thread, which is why we’re using our hands first and
a wrench next.
