Hi All,

Well after 10 years of weekend builds on Aug. 10th the L-4H will be getting assembled at the hangar. Two question for the group.

1. I have OEM expander tubes, I read all the posts here and find a few different recommendations.
Q: So what is the majority recommendations on the brake fluid I should be using? 5606H? 5606A? DOT 3 .... or?

2. I have a C85 completely overhauled with new Superior Millennium cylinders.
Q: What brake-in oil should I use and after the brake-in period, what oil should I use in the engine?

Thanks again for the help. Pictures will be posted soon!
