When a hose needs replacing
Usually one of three: it has been cut or chafed through, it is being shortened after a bar or fork change, or the brake is being rerouted through a new frame.
The caliper-end fitting has to match your brake. A bevelled banjo sits at an angle, for where the hose turns tightly out of the caliper; a double compression fitting is the straight-through arrangement.
This one really is a workshop job
Cutting a hydraulic line opens the system to air, and air in a brake line is exactly why a lever goes soft and pulls to the bar. Reassembly needs the barb and olive properly seated, then a full bleed with the right fluid — DOT for SRAM, and it is corrosive to paint.
Book it through our workshop. See also olives and inserts.
