Replacing brake fluid and clutch fluid. What r some brands that work well, or should I get oem? I have a light hum coming from rear, it slows as speed slows, belt is really tight so that could be the noise. If anyone has any info let me know as I am having it worked on this weekend by a friend that has a shop. Thanks in advance.

Don't worry so much about the brand of brake fluid. Worry about the type! If you put Dot 5 in a Dot 4 system, you could destroy your seals. This could be extremely expensive, give that there are no rebuild kits for Brembo calipers. Mine takes Dot 4. My mechanic buddy was about to pour Dot 5 into my reservoir when I stopped him. Although he seemed irritated that I insisted on Dot 4, I'm glad that I did after reading some horror stories about Dot 5 here.
As per the humming, the rear brake will hum or howl at low speeds. Replacing the pads doesn't help either (to my knowledge).
However, if you hear humming without using your rear brake, check your tire pressure and tread condition. My belt runs silently and it is supposed to be "really tight" with only 6mm (1/4") of deflection with a 10 lb. force (belt tension gauge required). Unless your belt is damaged or misaligned the humming more likely is the tire or wheel bearing.
Paint the inside black too.
