Brake and Oil cooling question

SeattleLion

I have a touring sport (just 3 weeks now) and have been enjoying this forum. There have been a number of threads about the brakes failing and oil overheating. These threads have been in the context of tracking the Z.

I don't plan to race. I do drive windy mountainous roads that sometimes demand braking and extra push from the engine (at least the way I drive).

Is there any reason for me to be concerned about brake failure? Do I need to flush the system and replace the brake fluid with SAE 5? Do I need to add an oil cooler?

I have not experienced oil overheating or brake issues to date. On the contrary, the Z's sport brakes feel great on the road.

Oh, one more thing. This is probably silly, but since this car is brand new to me, I think about small changes. When I took delivery and for the first 1,000 miles, the voltmeter locked in at 14 volts. Just what I would expect to be the generator output. The last few days it reads a solid 15 volts. I realize it is only a one volt deviation, but the fact that it is a change and not a transient one makes me wonder.

Thanks for your help.
