Remove the rear eccentric hub (sec. 7 - 13, Removal of the rear wheel eccentric hub and rear wheel shaft).
Undo and remove the four fixing screws (13) of the brake disk to the wheel axle and remove the rear brake disk (14).
Loosen the four screws (24) and remove the rear phonic wheel (25).
The brake disc must be perfectly clean, with no rust, oil, grease or other dirt and no deep scoring.
To check the wear limit of the brake disk refer to sec. 3 - 1.1, Hydraulic brakes.
Place the rear brake disc (14) on the rear wheel shaft (26), by orienting the bevelled edges (s) faced upwards.
Fix the disc by starting the screws (13) with prescribed threadlocker.
Note
Make sure to centre the screw heads in the relevant seats on the brake discs.
Tighten the screws (13) to a torque of 27 nm +/- 10% (sect. 3 - 3, Frame torque settings), in the sequence 1-2-3-4.
Position the phonic wheel (25) on the brake disc (14) by orienting it as shown in figure.
Fix the phonic wheel (25) by starting the screws (24) with the recommended threadlocker.
Tighten the screws (24) to a torque of 5 nm +/- 10% in a crossed-pattern sequence.
Refit the rear eccentric hub as described in sec. 7 - 13, Removal of the rear wheel eccentric hub and rear wheel shaft.
