Brake Fluid Testing Lab?

[RWebb]

I'm thinking of testing some old brake fluid when I flush it out this year.

What is a good, inexpensive testing lab to send it to (% moisture)?

Why not test it yourself?
There are many brake fluid testers available.
Some fancy digital ones are more expensive ($150), decent less accurate ons are about $40, and test strips are very cheap.

I use a refractometer at work and have an OTC 4598 at home

Randy,
Feel free to send it to me - I'll test it for you at no charge (metals, viscosity, oxidation, water...). Still have my address?

YEs, I do - Thx much!


BTW - are those $30 DIY electronic testers accurate?

[M.D. Holloway]

Conductivity meters I believe. Only thing it would tell you was if water was present. A quick and free way to test is the 'crackle method'. Get a metal spoon and put your test fluid in it. Put a flame under it as if you were prepping smack. If the oil crackles and pops when it gets really hot that means you have entrained water...
