Brakes problem
2003 Chrysler Grand Voyager limited 6 cyl Front Wheel Drive Automatic 134000 miles

I have a chrysler grand voyager 2003 limited edition, had an abs problem which I fixed it by changing the rear abs sensor. 2 days after I fixed the abs problem the car brake warning light in dash cluster started to come on when I put foot on the brake pedal. It turns off approx 10 seconds after I take the foot of the pedal or with in 2-5 seconds after putting the foot on the accelerator. Tried to retrive codes from computer but there is nothing there. Your help in this matter will be highly regarded thanks
