BLEEDING AND FILLING THE BRAKING SYSTEM (Continued)
With the bleeding apparatus.
Connect the bleeding apparatus [1]on the brake fluid reservoir (1).
Adjust the apparatus pressure to
2 Bars.
For each circuit:
Connect a transparent tube onto the bleed screw, submerge the other end of the tube in a clean container.
Open the bleed screw, wait until the fluid is flowing out without air bubbles. Close the bleed screw.
Remove the bleeding apparatus
[1].
Check the brake fluid level
(should be between «MINI»level and «MAXI»level).
Fill if necessary with the approved and recommended synthetic brake fluid.
Without the bleeding apparatus.
NOTE:Two operators are necessary.
For each circuit:
Apply the brake pedal to place the circuit under pressure.
Connect a transparent tube onto the bleed screw, submerge the other end of the tube in a clean container.
Open the bleed screw, wait until the fluid is flowing out without air bubbles.
Close the bleed screw. Remove the tool
[1].
NOTE:Recommence the process a second time if that is necessary.
Check the brake fluid level
(should be between «MINI»level and «MAXI»level).
Fill if necessary with the approved and recommended synthetic brake fluid.
