I'm in need of a brake master cylinder for my ride. Appears to be leaking between the reservoir and the cylinder (picture). Is there a seal that I can replace inexpensively without buy a whole master cylinder assembly? Can't tell if the master cylinder is the same as used on the Trooper because I don't have a Trooper parts manual. I don't know if the master cylinder is different when they went to the 1100cc engine. Has anyone had experience with master cylinder make for the Kinrod Joyner line of rides (I believe it's a German company)? They are available on Amazon but the configuration isn't the same as OEM.
