Auto Scanner: How to put the brakes on Ford Ranger's problems

I have a '98 Ford Ranger with 100,000 miles on it that is having Anti-lock Braking System issues. A few days ago, I had an occasion to stop very quickly in highway traffic and the ABS engaged. Now, whenever I stop quickly at approximately 15 to 20 miles per hour, the ABS will engage, and the wheels feel like they're gliding to a stop. When I engage the brakes softly, there's normal stopping. I've had my trusted buddy mechanic check all of the brake issues, the ABS sensor was replaced, and for the most part, the brakes are OK except for the hard stopping issue. There was a rubbing sound coming from the brakes while driving before, but now that has been greatly diminished. It can only be heard if you concentrate on it and there is no background noise. Do you have any advice for how I can fix these problems?

Let's start with the year and make of the vehicle. The '98 Ford Ranger had many issues with the rear spring shackles rotting out. When the shackles rot, the rear end can move on its own, independent of the body. So when you step on the brake, they will indeed lock up and cause the ABS to be active. The rubbing sound could be anything from a bent backing plate to a piece of anti-rattle hardware rubbing — or even a bad wheel bearing. That would have to be seen. So the first things to check are the rear shackles. If they are OK, go with your buddy for a road test, and attach a good scanner to the ALD port. Monitor wheel speeds, and when you apply the brakes, see which one falls out first, and you should have your culprit right there. Sometimes, especially with Fords, the rust under the sensor will give it a false reading. The next issue is the AllData monthly subscription your friend has. There is a wealth of information in the AllData system, and I consider it one of the best out there. I use it each and every day, as do millions of other shops worldwide. Here's the deal on AllData or any other information source: you have to know where to look for it. And that's where the problem is. There is no lesson that teaches you how to look within the system. This takes time, experience and experimentation. The nice thing about AllData is it has an A to Z look-up in the middle upper area of the menu. There, you can find just about anything.

Car Care Tip: Did you know Sylvania now sells a new and improved back-up light bulb? It's called the Silver Star Signal. It gives 30 percent brighter and 20 percent whiter light when backing up. Installing it is just like changing any car light bulb.
