i have a 1993 dodge d250 with a one ton front and rear end . i just replaced the brakes all the way around but when i start engine all warning lights will go off for a minute then the ABS and parking brake warning lights come on , i have bled the brakes and checked everything i can think off does anyone out there have any ideas on what to check. thanks

 

I have the same problem. Mine happened after master cylinder replacement. I replace brake light switch, no help. Also check sensor on rear axle. Let me know if you found a fix. Thanks

 

I took care of my problem. There is an abs valve with a bleeder screw above the left rear wheel. Also, I found corrosion in the connector to the abs sensor mounted on the rear axle. Hope this helps.

 

Same thing happened to me after I did a complete brake line replacement and brakes. I also replaced the ABS valve mounted to the frame at rear and the sensor on axle.
I did not replace the sensor on the rear diff.

The parking brake and ABS light still wont go off. Any solutions/advice out there?

I'm about ready to get into the dash and delete the warning lights.

 

probably air in the lines somewhere. no need to pull the bulbs. just unplug the abs module behind the glove box should turn the light off unless there is still air in the line causing the proportioning valve to keep the brake light on
