Bleeding the brake system without the brake bleeder - SAT 1175B -
  Caution
If one of the chambers in the brake liquid container is completely empty, also bleed the coupling system of the vehicle. Follow the instructions in → Rep. Gr.30 the switching instruction of the gearshift installed in the vehicle.
  Note
To carry out the post-bleeding, the aid of a second mechanic is required
   
–  If installed, remove the protective caps -1- of the four bleeder screws of the brake calliper / cylinder.
  Note
Mount the hose of the collector bottle -SAT 1175B/1- accurately on the bleeder screws so that no air enters the connection.

–  Beginning with the right rear wheel, connect the bleeding hose -1- of the collecting bottle -SAT 1175B/1-to the bleeder screw of the brake calliper / cylinder. Do not loosen the bolt yet.
–  Keep pressing the brake pedal controlled for building up the pressure in the cycle.
–  Press the brake pedal with force and maintain pressure while the second mechanic opens the bleeder screw, to which the collecting bottle -SAT 1175B/1- is connected.
–  Close the bleeder screw if the brake pedal reaches the end of its pedal travel. Then slowly loosen the brake pedal
–  Repeat the two operations described above until it is observed that the brake fluid appears without air bubbles.
