How to prevent brake fluid loss?
It is possible to minimize fluid loss by applying a vacuum to the top-side of the brake master cylinder reservoir, so that fluid is drawn up to the reservoir, rather being allowed to spill out of the open hose/line once it’s disconnected. However, you’d need to fabricate some kind of cover plate or cap with a vacuum port in it to which you could attach a vacuum pump of some sort. But even then, it’s still quite possible that you’d lose some fluid when disconnecting the line from the caliper. In addition, once you disconnect the line, the negative pressure in the reservoir will more easily draw fluid back up the line to the reservoir, which will introduce air into the system, which will then need to be bled out.
How often should I change brake fluid?
As to protecting the entire system and your life, it should be obvious that you want to replace all the fluid about every 2 years or a max of 50K miles. Please don’t argue with me about this, I have spend the last 40 years researching brake fluid, while developing OEM bleeder systems and OE Approved brake fluid testing strips. All Brake Fluid has an “acid shift” with usage (heat and pressure) and this raises acid leve while destroying the important anti-corrosives and buffering agents. This slow acid build-up will eventually allow corrosion to begin and that means parts will experience expensive damage and or failure.

In old cars bleeding the brakes is simple. But in new cars you want to be careful as some special tools can be needed to make sure all the bubbles are removed. I can tell you right now that there are vehicles on the road that have small air bubbles in the brake system that got trapped by the ABS system due to old school guys not understanding the new ABS systems. Sometimes a vacuum style bleeding can minimize those bubbles but the proper procedure will make sure there are no bubbles at all. Brake systems will often work ok with teeny bubbles but it will never feel quite right and will be annoying to anyone with any sort of OCD.
