2004 CTT Brake Fluid Flush Capacities

[pastorom]

I already have the motive bleeder and two liters of ATE Typ 200. My current brake fluid is also amber in color, so the traditional color change method doesn't work here, for me to figure out when to stop bleeding each valve. Given that there are 8 valves on the CTT, how much fluid per valve should i be draining? I figure measuring this is going to be the safest way to make sure i have a clean flush.

The lines are different lengths so measuring will not be accurate.

Just bleed until the fluid coming out (use clear tubing) is clear and the color of new brake fluid.

One liter should be enough to bleed all four brakes and PSM.

I tried one of the brakes, and the color of the fluid coming out was the same as that of the new fluid. There was a little debris for like the first few ml, but then it was clear. No bubbles either. I guess this is a good thing because it means that the old brake fluid is clean, but i find that a little hard to buy given that maintenance records (and the PO was meticulous) show no brake flushes for 195k miles!!

 

In any case, makes figuring out when the new fluid is coming that much harder. I let it go on until the fluid looked absolutely clear, no bubbles etc. 

 

I've left the power bleeder still connected, so will tackle the rest of the brakes later this evening.

Sorry to revive an old topic.

 

I have never done a brake flush before - I am taking it in to my Mechanic. Which one of these should I get:

And if so, how much of it should I purchase?

 

Thanks.

ATE Typ 200 is what the factory fill is. I would stick with that.

As I said in post number two: "One liter should be enough to bleed all four brakes and PSM."
