So I've been away from my bike while I've been at college, so I haven't been able to work on it. When I got it, the master cylinder reservoir was missing the cap, diaphragm, diaphragm plate, and the little metal protector that sits in the bottom of the reservoir. Since it's been sitting in the barn, it's collected a lot of dust and dirt in the reservoir. What would be the best method of fixing this? I know I can't just wash the brake lines out since brake fluid is Hygroscopic. Would my best bet be to just replace the line? And for the reservoir, could I just blow the dust out with some compressed air? Any help would be appreciated, it's a 1988 Honda shadow VLX.
