In a panic stop from approx. 50 MPR the front brakes do not lock up not do I feel any pulsing in the brake pedal or hear any clicking noise. I have done this repeatedly and always get the same results. Normal day to day stopping is OK. When I turn the ignition switch to the start engine position the ABS light come ON and when I release the key the light goes OUT. I've taken the truck to a local dealer and they find to error code(s). Rotors and pads both front and rear have been replaced and are almost new.

If the ABS lite is comming on, the module is detecting a problem in that system. There will most likely be a code in the computer. take it to your dealer and have it check. The most common problem i see in these is a failed speed sensor.

I have experienced problems with my Passat, when working on the brakes it is very easy to hit the sensors, these are a push fit, if they are not fully home the light comes on. simply push the sensors until they click home.
On a side issue I have problems with the traction control affecting acceleration in a corner, I traced this to a garage fiting a 60% tyre instead of a 65% tyre
Hope this helps

the brakes have to be bleed you wrote that when you start the car the pedal goes to the floor that means the booster is working fine take it back and tell them you want the brakes bleed

What happens is if you have a bad front wheel bearing when you brake that wheel will turn in or out,when this happens it throws the four wheel alignment out and since this is a solid rear axle,it's forcing it to flex on the suspension,wich could cause the rear tires to bite on the outside edge of one tire and the inside edge of the other,thats one possible the other would be that the rear brakes are are not slowing the wheels evenly causing the same issue.I saw this problem with a bad front wheel bearing on a Nissan Pathfinder but not as pronouced due to the independent rear suspension. Check the front wheel bearings,which of course will mean getting the calipers off the rotors,and then check for any movement in the rotor,if there is check the hub nut,if it's loose tighten it and check for play in the rotor if there is still play that's going to be caused by a bad bearing.You can check the braking in the rear with a simple spring scale(like the ones used for fishing),with the wheels removed have someone apply enough pedal pressure to just engage the brakes but still allow movement attach the scale hook to a wheel stud and pull until it starts to move and note how many pounds of pressure it takes to move the hub.If it's uneven chech your adjusters and even them if needed and then retest,if still uneven you'll need to bleed them again.As far as the dark black substance in the fluid I would say you may gotten a contaminent in the fluid.Brake fluid gets kind of a rusty reddish residue when it breaks down.If I missed anything or you need clarification don't hesitate to ask I'm home all day.Hope this helps solve your problem.
