I have been doing a lot of research on the rebuilding of the master cylinders on my 2001 Scout. One recommendation was that the fluid should be changed after 2 years because of moisture in the fluid. My bike has 17000 miles on it so I decided to do a rebuild with new DOT 5 fluid. After removing the cover on the rear master this is what I found. Water and contamination in the reservoir! I am also installing new brake pads and found that my Scout did not have anti-rattle springs installed. Mark at Moto Indian told me that some of the early Scouts came from the factory with no springs because of a clearance problem between the pads and the rotor. I ordered new springs and will install them if I have enough clearance to do so. I would be interested in other members experiences with the brake system.
