Bold reference numbers in this section identify parts not shown in the figures alongside the text, but which can be found in the exploded view diagram.

Open all the retainer clamps of the front ABS sensor cable (2): refer to table of Sect. 7 - 6, Flexible wiring/hoses positioning.

Undo the fixing screw (1) and remove the front ABS sensor (2) with the calibrated gasket (3), sliding the cable from the cable grommet (18).

Before refitting, make sure that the contact parts between the front ABS sensor (2) and its seat are not damaged and are perfectly clean.

Check the air gap between the front ABS sensor (2) and the front phonic wheel (19) as indicated in Sect. 7 - 7, Adjusting of the AIR-GAP phonic wheel sensor.

Tighten the screw (1) to the torque of 10 Nm ± 10% (Sect. 3 - 3, Frame torque settings).

Restore all the retainer clamps of the front ABS sensor cable (2): refer to table of Sect. 7 - 6, Flexible wiring/hoses positioning.

Open all the retainer clamps of the rear ABS sensor cable (5): refer to table of Sect. 7 - 6, Flexible wiring/hoses positioning.

Remove the rear ABS sensor (5) from its seat on the rear calliper holder bracket (7), undoing the fixing screw (1) and collect the calibrated gasket (3).

Check the air gap between the new rear ABS sensor (5) and the rear phonic wheel (D) as indicated in Sect. 7 - 7, Adjusting of the AIR-GAP phonic wheel sensor.

Fix the sensor to the calliper holder bracket tightening the screw (1) to a torque of 10 Nm± 10% (Sect. 3 - 3, Frame torque set­tings).

Restore all the retainer clamps of the rear ABS sensor cable (5): refer to table of Sect. 7 - 6, Flexible wiring/hoses positioning.

Drain the brake fluid in the pipes disconnecting these from the pump and from the calliper (Sect. 4 -3, Draining the brake circuit).

If it is necessary to replace one or more pipes, follow the instructions indicated in paragraph “Flexible wiring/hoses positioning” of this section.

Tighten the screws (17) to the torque of 23 Nm ± 10% (Sect. 3 - 3, Frame torque settings).

Refit the ABS pipe cover (4) and tighten the screws (16) to a torque of 3.5 Nm ± 10% (Sect. 3 - 3, Frame torque settings): make sure not to quench the cables placed underneath, especially the generator and the fuel tank ones.

To fill up the system, carry out the instructions for replacement of fluid of the pump or calliper to which the pipe is connected (Sect. 4 - 3, Filling the brake system with fluid).

If the ABS control unit is replaced, this must be supplied with secondary circuit already full of fluid; the control unit must be fitted and the system filled and bleeded as a traditional system.
