If your fluid is that black, I'd probably go ahead and get the entire brake system flushed. I'm going to have mine done next Tuesday.

DOT 3 and DOT 4 mix no problem

the syringe will work, but won't get the fluid in the lines are calipers, so it's not a full solution. Like JD said, you need to bleed the system

Go ahead and flush the brake fluid, just bleed every wheel until it comes out clean.

buy yourself the Motive Pressure Bleeder. It is easy to use.

Take the old brake fluid out of the reservoir.

Add new brake fluid.

Attach the pressure bleeder to the reservoir

pressurize the bleeder to 12-15 lbs.

open your bleeder valve and wait for the new fluid to come through

Just make sre you dont run out of fluid in the reservoir.

It is very easy to use and a 1 person job.

Another solution would be to install Speedbleeders on each caliper. They have a checkball built in them, you open the bleeder 1/2 turn and bleed that caliper. I also used Motorcraft high performance brake fluid. Supposed to be one of the higher boiling point fluids.

That is exactly what I do. I use 2 quarts of fluid, I use Castrol GT LMA (Low Moisture Absorbtion) but many here use Valvoline synthectic.
Yes makes bleeding your brakes a one person job, no need for "help" from the wife.

You could use the syringe, I did mine that way as my brake fluid was dark also. You need to do it at least one a week until the fluid is clear. Mine took 3 times and it's nice and clear.

Heck, it took me 40 years to train my wife on this; and, now, you tell me that she is "not needed." Are you crazy, man!!
