I drove my 91 740 today and when i went to break everything worked fine, right up untill the second before the car completly stoped. It felt like i was on ice and my car felt like it was sliding a little(it wasent), and the wheel jerked and then it stoped. It is comming from the front i know that. But im not sure what it could be, this just started happening. I know my rotors are a little warped, but maybe they become more warped?

 

Maybe the Strut rod bushings?

 

Hmm. I dont know what thoes are. But could they jsut go bad all of a sudden?

 

Went out driving jsut before, and the problem was gone. Maybe they were just sticky with the heat.

 

Might also be dirty ABS sensors if you have ABS on your car.

The strut rod bushings stop the control arms from moving foward and back.
