Pump the brake lever several times and hold the lever in. While holding 
the lever in, crack open the bleeder valve. The front brake lever will 
travel all the way to the grip and brake fluid and/or air will come out of 
the bleeder valve into the 6 mm hose. Tighten the bleeder valve before 
releasing the front brake lever. Pump the lever several times again and 
repeat the process. 

 

Be certain to check the master cylinder reservoir occasionally to make 
sure the reservoir doesn't run dry. Add more brake fluid as necessary. 
Continue this process until clean brake fluid comes out of the bleeder 
valve and there are no air bubbles. The brake lever should feel firm. 

 

Tighten the bleeder valve to specification and push its rubber cover over 
the nipple. 

 

(Air Bleeder Valve Torque: 7.5 N-m or 5.5 lb-ft) 

 

 

Make sure the reservoir has the proper amount of fluid.
