My Tr3A developed a major leak in the clutch master cylinder over the summer and when I took it apart I noticed that the rubber components had become soft and mushy. I'm wondering if this could be caused by contaminated brake fluid?? I converted the system to silicone fluid years ago and have never had a problem until now, so I'm thinking that I may have mistakenly topped up the m/c with synthetic rather than silicone fluid. Although the rubber parts in the slave and brake cylinder appeared to be okay I replaced them anyway, just to be on the safe side and now I'm trying to think of the best way to purge the brake system without possibly contaminating the rubber in the calipers and wheel cylinders. Any suggestions appreciated.
