Front brake fluid level check

I want to be sure that I'm interpreting my V7III manual correctly: "Turn the handlebar so that the fluid is at the same level as the plug." The "plug" is where the brake fluid line connects to the reservoir...correct?
 
You want the cover of the master level. Then check the sight glass. The translation probably refers to the sight glass as the "plug". About half way is good. Also when you fill, do not overfill as the caliper may not release as there isn't anywhere in the reservoir for the fluid to go.

I have a center stand. Do I put the bike up level on the center stand and straighten the bars to read, or do I use the side stand and then straighten the bars to read the level...(which is what I normally do)? Either is ok as long as the cover of the handlebar reservoir is level with the ground?
Thanks!
 
It is an important concept to understand, that a hydraulic brake is a closed system.

Unless there is a leak someplace, the level of the hydraulic fluid in the system, remains constant.

One should never need to add fluid normally.

Brake fluid in a manual brake system, should be flushed completely at least once every 2 years.

Brake fluid in an ABS brake system, should be flushed completely once every year.

Indeed.

And bleeding the ABS brakes on some bikes requires special software. This software activates the ABS circuit, allowing the otherwise trapped fluid to be expelled into the hydraulic circuit and ultimately flushed with clean fluid.

On the “special software” for bleeding: the rear brake on my V85tt is near useless with regard to the extreme amount of pedal to get effect. Using the syringe method I have completely flushed through more than 100% of the fluid to no improvement. Following that I have conventionally (pump, hold, bleed) bled enough to probably replace all the fluid again. No progress. Not clear how the anti skid unit impacts this flushing but I certainly don’t have, or have any idea how to apply, “special software”. Is this likely my problem? Any more info or explanation available? Thanks

The special software merely releases the trapped fluid in the ABS circuit to ensure all fluid has been displaced with clean fluid. You should be able to obtain effective braking by bleeding conventionally.
