Bleed your brakes without the worry of pushing a bunch of air into the brake system. This syringe can also be used to suction old fluid out of a brake system.


  • Heavy duty 60ml syringe
  • 6 inch chemical resistant hose
  • 1 spring clamp to secure hose to bleeder screw

Starting from a dry brake system with no fluid:

  1. Compress bleeder plunger all the way down inside syringe
  2. Put the end of the hose into a bottle of DOT4 brake fluid and pull plunger out, suctioning fluid into the syringe
  3. Connect end of hose to the bleeder valve on caliper, securing hose in place with the clamp
  4. Make sure master cylinder cap is removed so air can escape out the top, and loosen bleeder valve on caliper
  5. Push fluid into caliper by compressing plunger, it helps to tap or flick the brake line so no air bubbles form as you're adding fluid to the system
  6. Continue pushing fluid until the master cylinder is at 3/4 way full
  7. Make 100% sure you don't run out of brake fluid in the syringe, this will add air into the system
  8. Close bleeder valve
  9. Pump the lever several times to build up pressure in the system
  10. If you are not happy with the lever feel, you will need to bleed the system

Bleeding Brakes

  1. Pump the lever a few times and hold pressure
  2. Loosen the bleeder screw on caliper for a second, then tighten back up (you can leave the bleeder on the valve to catch fluid)
  3. Pump lever several times again to build up pressure, repeat process again until you achieve adequate pressure
  4. As you're bleeding, keep an eye on the fluid level in the master cylinder. If it runs dry you'll have to start all over again since you now have air in the system
  5. If you're bleeding by yourself and cannot crack open the bleeder valve and hold lever at the same time, try the Tusk Brake Bleeder from Rocky Mountain

Bleeding Troubleshooting

  1. If you cannot get good pressure with your brake system, try zip tying your lever to the handlebars overnight. This will force all the air bubble to the top of the system
  2. If all else fails, check master cylinder and caliper for bad seals and inspect brake line for bulging or leaks

Removing Old Brake Fluid From System

  1. Compress bleeder plunger all the way down inside syringe
  2. Connect end of hose to the bleeder valve on caliper, securing hose in place with clamp
  3. Open bleeder valve and pull plunger out, suctioning the old brake fluid into the syringe
  4. Refer to the first section of this guide on how to add new fluid and bleed the system
Watch this video on how the bleeder syringe is used.
