TRAC/Brake Fluid flush with DOT 4 ?
I am just in the process of performing the routine maintenance of flushing the brake fluid which I don't know the age of, but it looks nasty. Also, I am getting the TRAC light fault after the traction control has been used a few times. SOOOOO, my question is if it is advisable or not, to replace the existing DOT 3 fluid, with DOT 4? What would the advantages or disadvantages be? Are they interchangable if completely flushed/replaced? Is the TRAC compatable with DOT 4?
Thanks for your advice.

My thoughts were 1) A higher boiling point might help the pressure problem with the TRAC system faulting out. 2) My understanding is that DOT 4 fluid was designed to be superior to DOT 3 in all aspects, and that it is supposed to be compatible as a drop in replacement for DOT 3. So, I thought it would only improve operation.

I Have been Searching in many different Pages on ways to perform a Flush on the System. I Read that i am supposed to Turn on the Vehicle and Loosen the Bleeder that is located on the Nitrogen Canister Until the Fluid comes out Clear. After i am supposed to Repeat the Procedure on the TRAC Pump itself. but when i loosen the Bleeder on either location no fluid comes out. not even a Drop of it. Is there a way to make the pump work while the Vehicle is Idling?? Or is it supposed to be working on its on while idling??

BTW, from my searching, I believe that it would make sense for my particular issue to be caused by bad fluid in my TRAC and lines. I will elaborate on my TRAC fault issues once I have had a chance to change all the fluid.

From all of the searching I have done on all the forums. It appears that if you raise the drive wheels off the ground and put it in drive, then put on the brakes, it will sense different wheel speeds and actuate the pump.

As your TRAC light is already on and there is no fluid coming out when you open the bleed nipples on both the nitrogen canister and the pump it may be due to the fact the nitrogen accumulator is empty.
What TRAC fault code do you have? If it is the usual error 41 TRAC motor running for too long chances are it will be the accumulator.
Even with the engine off there should be enough reserve pressure in the nitrogen accumulator to push the brake fluid out.
I had the same problem with both the TRAC light on and unable to bleed fluid but after replacing the accumulator with a spare I had regassed all worked as it should.

I Don't have a TRAC Light on. My system Just Doesn't work. i Try pulling codes and i get Continuous Flash (No Codes). So if the Canister is Empty The TRAC System will not work?? Where can I get a Canister Re gassed??

Sorry I read you were getting the "Trac light on when the traction control has been used a few times" so I assumed it was stopping on indicating a fault/code.
I had my accumulator done at a local hydraulic engineering company here in the UK, there is also a guy at the UK Soarer Santuary who offers a complete exchange rebuild with new seals for around $180.00 (120.00GBP) but I don't know if he ships internationally.
Could you not try pressure bleeding the brake system?
