Anti lock rear brakes

[frank-id]

Ya know, I really like my old 1991 Ford F250 Diesel Lariet
Pickup Truck. I use this truck for every task. While joyfully driving to get some lumber, the anti lock lite on the dash comes on. The roadway was dry and smooth, and the lite came on. My brakes are good and work well. What and where shall I check to turn off the lite.?? I have had no previous problems with anti lock system. In Idaho, Frank

Check your brake fluid level.

Your rear brakes could be out of adjustment.The automatic adjusters don't work for crap

There's a RABS sensor on the top of the rear axle. Check to make sure the conector didn't come off. The sensor sometimes go bad, or the rabs module could be bad.

There are a few tests out there to trouble shoot the parts. Apparently I cannot find them on my computer.

There is a troubleshooting proceedure in the manual. There is a test lead you short, and the light will blink out a code that will point you in the right direction.

the only time the abs light came on for my truck is when the fluid level was low
