When replacing the brake pipes (33) or removing one of the rear braking system components, pay special attention to the position of the couplings on the pump and the calliper.
Warning
If incorrectly positioned, the hose can affect brake operation and foul moving parts. Position the hose as shown in the figure.

Remember to fit the copper faced sealing washers (23) to the hose end fitting when reconnecting the brake pipe to the brake calliper (15).
After orientating the fitting, lock the special screw (22) to a torque of 23 nm +/- 10% (sect. 3 - 3, Frame torque settings).
If the speed sensor (1) was removed, fit it on the calliper holder bracket (a) with the spacer (8) and the washer (32) and tighten the screw (2) to a torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings).
Note
The gap between the sensor (1) and the brake disc fixing screw must be within 0.6 To 2.2 Mm.
If it is necessary to remove the calliper holder bracket (a) in order to refit it, see sec. 7 - 13, Refitting the rear wheel eccentric hub and rear wheel shaft.
Insert the rear brake calliper (15) on the brake disk, aligning it with the holes of the calliper mounting bracket (a).
Grease the screws (12) and tighten to the torque of 25 nm +/- 5% (sect. 3 - 3, Frame torque settings).

In order to fit the pipe (33), the speed sensor (1) and the retaining clamps follow instructions in sect. 7-6, Flexible wiring/hoses positioning.
