This happened to me for the first time the other day. I was pulling into a parking space. This was flat pavement and when I went to brake it almost seemed as though my truck was on ice and my peddle popped about 3 times. there was no ABS light and now my peddle seems alot softer then usual. This doesnt happen all the time but has happened to be atleast 5 or 6 times randomly. Nothing really common between all the instances. I had a garage check it and they said it showed a code "Brake Pedal Position Switch Failure" but told me they were unable to help with that. Has anyone experienced anything like this? I have brakes but as i said the peddle now is alot softer and I want my stiff pedal back.
