• Tried this again after moving the lever reach to different positions but I’m still not able to push brake fluid through the system. Anyone got any ideas? Possible blockage in the hose? It’s strange as the brake was working fine before sending it off to Sram for a warranty on the broken gear shifting. Now the gears work but the brake doesn’t... Facepalm emoji.

  • Why don't you isolate it first. First remove hose from shifter (it's a faff) and see if there's any debris there.
    Then reconnect and remove hose from caliper, see if fluid moves through system. If it does, then move on further down the system. Connect syringe to calipers and push fluid through, see what happens.

  • If you squeeze the lever does it move at the caliper?
