I have a 1994 brougham. While I was driving the ABS and traction control light both came on the dash and wont go out. The brakes seems to be working fine when I stop. The only difference I have noticed is that when I start to stop or turn corners or even sometimes when I take off I hear squealing. The squealing seems to be 50-75% of the time. I have taken off slow and fast and drove around corners slow and fast and you still hear it squealing. All brakes are only about 1-2 months old. What could be causing the abs light and traction control light to be staying on and is it still safe to drive in your opinion?
