I have a 96 2wd 4.9L f150. I have owned it for two years now. Its starting to get cold outside again, which brings me to my problem. Last year I noticed that the rear antilocks weren't funtioning properly when it was cold and the vehichle had been setting awhile. In the morning on the way to work, when i touch the brake for the first couple of times the antilock system engages. It engages with very minimal pressure on the pedal. What would normally be a soft stop turns into wiplash. And it usually does it when i try to stop from 5-25 mph. I dont notice it once the truck warms up, or when i make higher speed stops. I know that they have had problems with the RABS valve in the trucks up till 95, but they suposedly fixed it in the 96 model. It NEVER does this when it is warm (above 60). My front discs are in good shape, and the rear drums are imaculate. Has anybody else had this problem? I keep getting told by mechanics that it is "normal" for cold weather... I think bunch of BS... any thoughts?

Thanks ahead of time

 

I think Ford has a revised brake shoe(s) that are tapered . Any moisture causes the brake shoes to grab . The tapered shoes dont have the squared off edges which is why they grab esp when wet . Its a common problem if you live in cold damp climate or when winter weather sets in .

 

I have the same problem on mine. The way I avoid the problem is when I start up in the cold morning,is to pump the brake several times before leaving the driveway. This has worked for me.

 

I have the same problem in my 90 F-150. It seems the anti-lock is only for the rear. But I usually ride the brakes for a few feet after taking off. This warms them up and hopefully gets rid of the moisture. I'm sure the brakes wont last as long, but I don't like having them lock-up after barely pushing the pedal.
