While driving on the freeway and applying my foot on the brakes the vehicle failed to stop. abs, traction control and a wrench light came on. grinding noise came from the vehicle. this incident happened while driving my wife and newborn home from the hospital. after taking it to a shop, the mechanic noticed that the tone ring or abs ring was cracked. this must be replaced in order for the vehicle to have functional brakes. the shop told me that the abs ring had a different part number and the material was much thicker than the old ring. *tr
