- Couple a transparent tube on the bleed screw.
- Submerge the other end of the tube in a clean container.
- Open the bleed screw.
- Wait until the fluid flows out without air bubbles.
- Close the bleed screw.
NOTE:Recommence the process a second timeif that is necessary.
Check the level of the brake fluid
(between the «DANGER»level and
