I have searched and did not find a problem similar to mine. My brake and abs lights have been staying on 85% of the time.

Here is my problem. When the brake and abs lights go out, my rear abs comes on when it shouldn't. When slowing to a stop in town, I apply the brakes and have about 1/2 of my normal braking force. I push a little harder and I hear and feel my abs valve. I do not have a abs motor. As the brakes are pulsating I push a little harder and the front brakes grab hard and I come to a stop. It seems to me that the abs valve is malfunctioning or something else that controls it. I have replaced the master cylinder, sensor in rear end, front rotors, calipers, and pads. Has anyone had this problem? Can I just bypass the abs valve. In my opinion the the rear abs is useless and I can do with out it.

Thanks for your help

Check to make sure your brake shoes are not covered in rear axle lube. The rear axle seal wear out and leak, causing the shoes to be over senitive.

Bigdenny,

My brake shoes are fine and there are no leaks. I need to know what makes the rear abs work, so I can look at each part in the system. When the abs/brake lights are OFF is when the rear abs acts up. When the lights are on, my brakes work fine. I just don't have rear abs.
