I took my 2001 blazer in to replace the upper and lower ball joints, pitman arm, and to have the tires realligned. As soon as I left the shop my brakes started acting up. The ABS system kicks on every time I brake. This was not happening before I had the work done, but the shop denies the work they did has anything to do with it. They say it's because the brake cylinder is leaking, though it looks to have sufficient brake fluid. Are they wrong?

 

Look at the wires from the ABS sensor on each wheel to see if they were damaged in any way.

 

I am going to take it to the dealer tomorrow. I will mention your advice. I wouldn't really know what to look for if I did it myself. If they do find damage, do you think I can get the shop that did the initial work to fix it for me, free of charge? I'm having a hard time believing they had nothing to do with this new issue.

 

They will probably say that they didn't do it even if the sensors are damaged. They will say that the damage occurred after you picked up the truck.
