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.
Removal of the rear brake system
Important
The brake master cylinder manufacturer advises against servicing the brake master cylinder due to the safety critical nature of this component. Incorrect overhaul of this component could endanger rider safety.
Operations should be limited to renewal of the pads, fasteners and the bleed valve assembly.

Operation | Section reference
Draining the brake system | D 4, Draining the brake circuit
Remove the banjo bolt securing the hose to the rear brake master cylinder and recover the sealing washers | F 4, Removal of the rear brake master cylinder

Unscrew and remove the banjo bolt (1) securing the hose (6) to the rear brake caliper and recover the sealing washers (2).
Notes
Keep a cloth at hand to wipe up any brake fluid that leaks out of the hose.
Undo the screws (A) securing the brake hose to the swingarm and remove the hose (6), complete with clip (B).
Before removing the brake caliper (3), remove the clips (C) securing the wire of the rear wheel speed sensor to the brake hose.
Unscrew the screws (5) securing the rear brake caliper (3) to the caliper mounting bracket (10) and remove the caliper.
Notes
For the brake pad renewal procedure, refer to Sect. D 4, Checking brake pad wear and changing brake pads.
To remove the speed sensor (13), undo the screw (12) securing it to the caliper mounting bracket, taking care not to damage the spacer (7).
Only the following parts should be renewed:
caliper: pads, fasteners and bleed valve assembly;
master cylinder: control pedal, bleed valve assembly, reservoir and its components.
Refer to the exploded view at the beginning of this section for indications on renewal of the above components.
To remove the caliper mounting bracket, first remove the rear wheel (Sect. G 4, Removal of the rear wheel).
Slide the caliper mounting bracket off the swingarm pin (D).
Refitting the rear brake system
Relocate the caliper (10) on swingarm pin and on the pin (D).
Refit the rear wheel (Sect. G 4, Refitting the rear wheel).
If removed, locate the speed sensor (13) on the caliper mounting bracket with the spacer (7) and tighten the screw (12) to the specified torque (Sect. C 3, Frame torque settings).
Fit the copper sealing washers (2) to either side of the hose end fitting when connecting the brake hose (6) to the brake caliper. Orientate the end fittings of the hose (6) on the caliper as shown in the photto.
Warning
If incorrectly positioned, the hose can affect brake operation and foul moving parts.
Tighten the banjo bolts (1) to the specified torque (Sect. C 3, Frame torque settings). Locate the brake hose (6) on the swingarm and secure the clip (B) with the screw (A).
Fit the rear brake caliper (3) over the brake disc, aligning it with the holes in the caliper mounting bracket. Grease the threads and undersides of the heads of the screws (5). Tighten the screws (5) to the specified torque (Sect. C 3, Frame torque settings).
Notes
The gap between the sensor (13) and the brake disc screw (12) must be between 0.6 and 2.2 mm.
