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. G 9.2, Flexible wiring/hoses positioning.

Remove the front mudguard (Sect. E 4, Removal of the front mudguard) and remove the speed sensor mounting bracket (4): the bracket is fastened by the two screws (B) retaining the front mudguard (left-hand side).

Before refitting, make sure that the contact parts between the front ABS sensor (2) and its seat on mounting bracket (4) 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. G 9.3, Adjusting of the AIR-GAP phonic wheel sensor.

Fix the bracket (4) with sensor onto fork leg with the screw (1) and tighten it to the specified torque (Sect. C 3, Frame torque settings) then refit the front mudguard (Sect. E 4, Refitting the front mudguard).

Restore all the retainer clamps of the front ABS sensor cable (2): refer to table of Sect. G 9.2, Flexible wiring/hoses positioning.

Remove the right-hand footrest bracket (Sect. H 4, Removal of the footrest brackets).

Open all the retainer clamps of the rear ABS sensor cable (5): refer to table of Sect. G 9.2, Flexible wiring/hoses positioning.

Remove the rear ABS sensor (5) from its seat on the rear calliper mounting 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 (11) as indicated in Sect. G 9.3, Adjusting of the AIR-GAP phonic wheel sensor.

Fix the sensor to the calliper holder bracket tightening the screw (1) to the specified torque (Sect. C 3, Frame torque settings).

Restore all the retainer clamps of the rear ABS sensor cable (5): refer to table of Sect. G 9.2, Flexible wiring/hoses positioning.

Refit the right-hand footrest bracket (Sect. H 4, Refitting the footrest brackets).

Drain the brake fluid in the pipes disconnecting these from the cylinder and from the calliper (Sect. D 4, Draining the brake circuit).

Should it be necessary to replace one or more hoses, follow the procedure outlines in the following paragraph to determine the hose routing on the vehicle.

In particular, use a new gasket set (11) and tighten the screws (23) to the specified torque (Sect. C 3, Frame torque settings).

To fill up the system, carry out the instructions for replacement of fluid of the cylinder or calliper to which the pipe is connected (Sect. D 4, 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 bled as a traditional system.
