Changing the rear brake circuit fluid
Remove the rear brake calliper (1) by loosening screws (2).
Undo screws (A) and remove the two cable grommets (B) and the upper cable guide (C).
Unscrew plug (3) of the rear brake fluid reservoir (4).
Rear brake calliper (1) shall be set as high as possible during the whole procedure (with drain plug facing upwards, as indicated in the figure).
Fit a shim of the same thickness as the disc between the rear brake calliper pads.
Connect a transparent tube to the bleed valve (5) and immerse the end in a container.
Warning
We recommend using a new container of SHELL ADVANCE BRAKE DOT4 fluid.
1
Press the brake pedal to pressurise the circuit.
2
Keep pedal depressed.
3
Loosen bleed valve (5) by 1/4 if a turn so as to allow fluid to come out and push the pedal all the way down.
4
Tighten the bleed valve again.
5
Release the brake lever and top up reservoir (4) until fluid level is between the "MIN" and "MAX" marks. During such operation always ensure that the fluid is above the minimum level in order to prevent air from entering the system from the reservoir.
Repeat the operations from 1 to 5 until you see clean fluid with no impurities and air bobbles flowing out.
Tighten bleed valve (5) to a torque of 4 Nm ±10%.
Use absorbent paper to remove any fluid residue from the drain plug hole and after that, refit the rubber cover.
Move the calliper pistons completely back pushing onto the pads; then, top up the reservoir until the MAX fluid level is reached.
Remove the rear brake calliper shim.
Apply the recommended threadlocker on the screws (2).
Insert the rear brake calliper on the brake disc, aligning it with the holes of the calliper holder plate. Then tighten screws (2) to 25 Nm ±5%.
Operate the brake lever repeatedly until the pads rest against the disc and make sure that the fluid level in the reservoir is between MIN and MAX marks; if not so, top up.
After removing the membrane from the plug and before fitting it again on the reservoir, clean it and dry with absorbent paper.
Tighten plug (3) of rear brake fluid reservoir (4).
Position the upper cable guide (C) and fix the two cable grommets (B) by tightening the five screws (A) with pre-applied threadlocker to a torque of 5 Nm ±10%.
Test the motorcycle on the road at a speed of about 50 Km/h; activate the ABS 10 times at least, by operating the rear brake only.
Ensure that the rear brake lever stroke has not increased and if needed repeat the bleeding procedure.
