Note. The brake system should be bled after repair work or if air is suspected in the brake lines.
Pic. 6.6. Filling the expansion tank with brake fluid
Fill the expansion tank with brake fluid (pic. 6.6).
Brake fluid: SAE J1704 or FMVSS #116DOT4.
Removal of air from the main brake cylinder
On models not equipped with Stability Control (VSC) Using the SST tool, disconnect the brake lines from the brake master cylinder.
Pic. 6.7. Bleeding the brake circuit
Note. Bleed the master cylinder if it was disassembled or there was no fluid in the reservoir (pic. 6.7).
On models equipped with a stability control system (VSC) Using the SST tool, disconnect the brake lines from the brake master cylinder.
Slowly press and hold the brake pedal.
Pic. 6.8. Blocking the holes of the brake cylinder
Close the master cylinder holes with your fingers and release the brake pedal (pic. 6.8).
Repeat the bleed operations 3 or 4 times.
Removal of air from the tubes of the brake system
Connect the vinyl tube to the bleed valve.
Pic. 6.9. Removal of air from the tubes of the brake system
Press the brake pedal several times, then loosen the fitting while pressing the brake pedal (pic. 6.9).
As soon as the brake fluid stops flowing out, tighten the fitting and release the brake pedal.
Repeat the operations described above until the air is completely removed.
Tighten the bleed screw.
Tightening torque: 10 Nm.
Repeat the described sequence of actions and remove air from the brake pipes of other wheels.
Checking the brake fluid level in the hydraulic reservoir
Check the fluid level in the hydraulic drive reservoir, add brake fluid if necessary.
