- Extract the main cylinder (consult “Extracting the rear
main cylinder” in this section).
- Dismantle the rear main cylinder.
- Check that there are no scratches, corrosion or holes in
the inner walls of the main cylinder and on the outer part
of each piston.
If any damage is discovered on the master cylinder or
on the pistons, change them.
- Examine the primary and secondary seals.
- If a seal is worn, soft (perished) or swollen, change the
piston assembly to renew the seals.

- Check that the anti-dust boots are not damaged.
If they are, change them.
- Check that the piston return is not damaged. If it is, renew it .

engraved side faces outwards.
- Apply a temporary blocking device to the threads of the
brake disk mounting bolts.
- Tighten the rear brake disk securing bolts.
