Brake Fluid Tester

[racingbmwm3]

you're going to spend more on testing than the cost of new brake fluid. it only takes a couple pints to flush the system. unless you are using Motul racing fluid, which is very unnecessary unless you are racing the X every weekend, at which point you need to change racing fluid more often anyways.

every 2 years will prevent you from having corrosion problems in the brake system. That's all you should be worried about. It takes a good 3-4 stops from triple digits before you have to worry about a lower boiling point caused by moisture content.

Buy a pressure bleeder (Motiv) for $50~ and a few pints of brake fluid. Your return on investment is 1 brake fluid flush. Every flush after is saving you $70-100. Recycle your old fluid at the parts store or the hazardous waste collection center. Don't mix with other fluids as it makes those other fluids no longer recyclable.
