Need some help I have Audi 2000 2.7T Quattro manual that the front right and back left brakes are locking up after about 6 to 8 miles of driving I pull over and the 2 brakes are very HOT the car will not move until it cools down . I have replaced the ABS Pump & Module ($1300) but that didn't work but the ABS light dose not come on any more Please any feedback would be much appreciated.

 

Did you replace the hydraulic block bolted to the module? Or just the module?
Its sounds like the valve inside the block is getting stuck, the right front and left rear brakes are tied together.

 

Yes I Replaced the ABS Module & the Pump Every body I talk to is stumped

 

Something is stuck in one of the lines then, when they changed the block it might have gotten something stuck in the block or the lines. Its the only way that can happen without any fault codes.
I would have them take all the lines off of the pump, take off the lines from all four calipers and use compressed air to blow out the lines, and use compressed air to blow out the ABS block.

 

this is a very strange case, it would sound to me as if there is a faulty sensor in play here, am sure you have a already checked the ABS sensors, i will go with wild guesses, take a look at the speed sensor and electronic stability sensor if the car is equipped with these
