I found that I had a major hydraulic fluid leak after this weekend's Trail must have been lead footed SWAMBO , looking at the fluid sprayed on the inside of the rear right tyre; it was the evidently the Rear Right Brake Cylinder Seals.

The answer - to strip and install a Seals Kit; Moto or Euro Parts Code: P 832 (Generic)

The procedure was pretty straight forward, I tried to document it well given that I didn't do peekchaz when I replaced the shoes last month.
