The other day I was driving my 1992 F150 when the rear ABS and brake light came on and the left rear drum brake strarted draging. I am not sure what would cause this type of problem so I am not sure how to fix it. Has anyone else had this problem in the past and if so what didi you have to do to fix it.

 

My truck would do this the fix was backing up and hitting the brake 5 times hard from 10 mph that adjusts the rear brakes. Check the fluid as well as that will cause both lights to come on. Hope this helps

Yes. It adjusts the lash on the rear brakes.

Or you can take it apart and adjust it manually.
