Pressure applied to the brake lever during the brake fluid renew process must be
applied and removed smoothly and slowly. It must take a minimum of five seconds
between lever positions (from fully released to stop).
Failure to do this slowly can allow air to be drawn in to the system through the bleed
screw threads.
7. Get an assistant to slowly pull the brake lever to the handlebar and then slowly
release the brake lever.
8. Repeat step 7 until fresh brake fluid appears in the bleed tube.
9. When fresh brake fluid is in the system, apply pressure to the brake lever, close the
bleed screw and tighten it to 8 Nm.
10. Remove the bleed tube.
11. Replace the bleed screw cap.
12. Fill the reservoir to the upper level with new DOT 4 fluid.
13. Repeat steps 4 to 12 for the other front brake caliper.
14. When the brake fluid has been renewed, make sure the brake lever operation has a
firm resistive feel to it, does not feel spongy and that the lever cannot be pulled
directly back to the handlebar. Take remedial action as necessary.
15. Fit the insert to the diaphragm seal. Make sure the locating lug on the insert fits into
its hole in the diaphragm.
16. Fit the diaphragm and insert assembly to the reservoir cap. Make sure the holes for
the fixings are correctly aligned.
