Hey yall, I figured I would look for some input here....

Just did a complete brake fluid flush on my truck. I cycled 2 1/2 Liters of new fluid through the system starting at the p/s rear pulling 3 pints of fluid from the caliper, then 3 more from the d/s rear on to the p/s front pulling 2 from there and 2 from the d/s front never letting the reservior get below the LOW mark.

The thing is, it never got clean. It stayed looking green and very very dirty, like it had a carbon dust in it clouding it very dark. I was emptying it into a mason jar from my vacum hose so I saw it all the entire time. Hell i have never seen green brake fluid for that matter..

The brakes feel a bit stronger but nothng to brag about like i have read on other threads. Does anyone have any thoughts on this or is it normal and i just need to flush it more.

Thanks yall
Mike

You can cycle the fluid all you want through those brake lines, and it won't come out clean. My guess is that it gets discolored from the inside of the brake lines/bleeder screw due to corrosion, but nothing you have to worry about. Just cycle enough fluid through to get the old stuff out and the new stuff in.

I do believe im gonna put steel braided lines on it where ever I can real soon. Not only will maybe solve that it will also firm up the dang pedal a bunch.

Did you start by sucking the majority of the old fluid out of the master when you started? Usually that helps doing that, then adding your new, then start with the bleeding...

And, the source of your poor brake performance, especially post #7 http://www.dieselplace.com/forum/showthread.php?t=146597&highlight=soft+brake

Well I have to say that now that I have read the entire spongy brake thread, and how to fix it, it all makes great sense. I just discounted the fact that this was a newer truck and shouldnt have to worry about stuff like this...Oh well, looks like I have another project to do...good times

Thanks for the input and tech advise

To answer your question, I went almost to the LOW mark but got a little nervous, my driveway is on a bit of a slant so I didnt want to suck in air. I really dont think the fluid is the problem after reading the other thread so i think Im gonna do what HEYMCCALL was sayin and take some pics while im doing it....We will see how it works out..

thanks again

Hopefully you'll take better pics than these.

Those weret bad pics, they get the job done. The bad part is I have a 1000 mile trip to take and dont have the time to do this before I go. When I get set up in my new garage in NC I will be sure to do a nice little step by step and have my wife take the pics while im working..lol

Again thanks for the help, I wouldnt have even thought about the caliper floating problems.
