I have a 99 F-150 two wheel drive. When I turn left at a slow speed and engage the brakes the ABS comes on and goes through the cycle system. You can turn right or go straight and everything is fine. The ABS light will come on when it happens and when you use the brakes again it will go out. This is when you do not turn left but just normal straight braking. I know some of you will tell me not to turn left and it will be okay but I can't do that. Thanks for reading.

 

Jack up the front end and carefully check each front wheel for a worn or loose front wheel bearing.
When you turn and use the brakes, the wheel bearing may shift slightly where the wheel speed sensor can’t quite read the ABS tone ring and the ABS thinks that wheel is sliding and invokes the ABS.
