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.

Brake fluid is corrosive and will damage paintwork. Avoid contact with eyes and skin. In case of accidental contact, wash the affected area with abundant running water and consult a doctor if necessary.

For all the maintenance operations (wear check and replacement of brake pads and brake fluids, etc.) see Sect. D 4, Draining the brake circuit.

For the ABS front braking system, also refer to Sect. G 9.1, ABS system operating information, Sect. G 9.2, System components, Sect. G 9.3, ABS components maintenance.

Unscrew the banjo bolt (6) securing the brake hose to the master cylinder and recover the sealing washers (4); slide hose (8) out of front master cylinder.

Remove the hoses (8) and (26) from ABS control unit (Sect. G 9.2, Removing of the ABS control unit).

While removing the front brake hose, if you damage the hose clip (24) you shall renew it (Sect. E 4, Removal of the front mud­guard).

Remove the master cylinder (Sect. F 3, Removal of the front brake master cylinder).

For correct position of the ties fastening the ABS sensor cable (B) to front brake lines (15), please refer to Sect. G 9.2, Flexible wiring/hoses positioning.

The front brake discs consist of an inner carrier, which is mounted to the wheel, and an outer rotor. Both parts must be changed together as a pair.

Critical safety components. The manufacturer of the brake calliper advises against servicing the internal components of callipers. Incorrect overhaul of this component could endanger rider safety.

To check brake disc wear, refer to the service limits given in the paragraph “Hydraulic brakes“ (Sect. C 1.1).

Before refitting the brake disc to the wheel, clean all contact surfaces thoroughly and smear a medium strength threadlocker on the threads of retaining screws (14).

Tighten the screws to the specified torque (Sect. C 3, Frame torque settings).

When reassembling the system, pay special attention to the position of the end fittings of front master cylinder-control unit hose (8) (onto cylinder and control unit), of control unit-front calliper hose (26) (onto control unit and calliper) and front brake line (15) (on callipers).

When reconnecting the brake hose to the calliper, the control unit or master cylinder, make sure to install the sealing washers (4) either side of the hose end fitting.

After orientating the coupling, lock the banjo bolt (6) to the specified torque (Sect. C 3, Frame torque settings).

Reconnect the hoses (26) and (15) to the front brake callipers (3) and (10) and tighten the screws (17) to their specified torque (Sect. C 3, Frame torque settings).

Duly reassemble the hoses (8) and (26) to the ABS control unit (Sect. G 9.2, Refitting the ABS control unit).

Tighten the screws as a first stage to the specified torque (Sect. C 3, Frame torque settings).

Repeat the operation for the left brake calliper (10).

Hold the lever pulled in towards the grip and tighten the calliper screws (2) to the specified torque (Sect. C 3, Frame torque set­tings).

Insert hose (26) in bracket (12) and tighten screw (16) to the specified torque (Sect. C 3, Frame torque settings).

For correct position of the ties fastening the ABS sensor cable (B) to front brake lines (15), please refer to Sect. G 9.2, Flexible wiring/hoses positioning.
