Instead of buying the test strips, I always check to see if I'm getting conductivity thru the brake fluid by hooking up the negative lead of my DMM to the battery's negative post, and putting in the positive lead of the DMM into the brake fluid reservoir (only touch the fluid) -- look for less than 0.5VDC (less than 0.3VDC is preferred).

You can also use this technique for the coolant to see if you have bad grounds which would cause conductance through the coolant.
