When I was working on gyro's the discussion was about anodizing, in the fact that the process did weaken the base material aluminium as the heat applied and that a very thin layer was weakened in the process. I don't think a chassis would be under such stress as to be a worry. But I thought I would bring it up.
With regards to the twin master cylinder setup, It looks like if one side should fail for some reason , then the balance bar would kink over at such an angle that it would still push on the good master cylinder. That's why the 20 thou clearance and washers adjustment is important so it can only go a certain angle.
I assume that the switch near the master is the brake light switch? And the other on the chassis the fail?
I'm trying to work out how that is routed?
So could you now call a pace a true kit, seeing that just about all the components come in a big box?
