2006 Silverado brakes

Anyway to clean the sensors at the front wheel bearing assembly or is that wishful thinking. The truck takes an extra second to fully stop. I don't mind doing the work but trying to figure if I should just take it to a pro and be done with it.

Is there a vibration and feedback in/from the pedal from the ABS when stopping? If not, the sensors have nothing to do with the increased stopping time. The cleaning prodedure is in post #6 in the link.
I think most people end up replacing the hub assembly, some seem to get by with cleaning, but you may have to do it multiple times.

I had similar issues on my 2001. I researched how to fix it, didn"t like what I learned, so I pulled the fuse and disabled the ABS. Best thing I ever did to that truck. On dry pavement, the truck will now stop in a much shorter distance than it ever did before. Even when new.

As mentioned there is a fuse just for the ABS in that fuse box under the hood. Pull that and see how it works. The two speed sensors that control the ABS are probably failing. Had that happen on my 2005 late last year.

dads got a 99 chevy and did the same thing, most of the time the sensors snap off when you try to take them out, i replace one hub/bearing while ago cause it was noisey, so i replace other one abs problem solved but he claims its back now but it hasn't done it to me yet

Are you just having a perceived stopping issue, or is the MIL on? If so, did you pull the codes, if NOT, thinking the sensors need to be cleaned is pure speculation!

The cure I have heard about is just pull the sensors and clean the rust and put them back in. I have been told this is a common problem. Soak them with some ATF and go for it.

Despite what everybody thinks, the ABS proponents never said that you could stop sooner. They brainwashed everybody into thinking they were so much better by saying that you could control your brakes from locking up on slick or wet conditions. Matter-of-fact, most state driver's handbooks will clearly state that ABS braking may take longer than non-ABS brakes. They even had the insurance companies tricked into giving cheaper rates to owners of cars with ABS. As said previously, pulling the fuse will not hurt anything except to disable the ABS.

Is it setting an ABS code ? If not ,leave it alone . There is nothing to clean that will make it work any better if there are no codes .

And you're saying that ABS DON'T work better than "regular" brakes on snow or wet conditions? If you are, that is a truckload load of BS.

Have you ever ran into one that goes into false activation if not its no fun and it will not set a code cuzz it thinks a wheel is sliding when its not,, it will scare the ell out of you cuzz it will just roll on thru a intersection while you are standing on the brakes...

I'm sure he'd agree with me, but ABS does next to nothing in the way of stopping distance, other than increase it in nearly every condition. What it does do is allow your wheels to continue to turn, which gives you directional control. That's the ONLY reason it exists, and for that it performs as designed. If the ABS cycles, you would have stopped sooner than if it weren't there, the only exception being pure ice. Slow down if your ABS cycles on wet pavement. Short of a small car with slick tires like a Corolla or Civic, ABS should never activate on wet pavement.

The purpose of ABS has never been to reduce stopping distance, which is not to say it doesn't do so under most conditions. A very good driver without ABS can equal the stopping distance of ABS under the right conditions, maybe even improve on it, but overall ABS is going to give shorter stops.

Why? Two reasons: First, most drivers will lock up the brakes in a panic stop, and the static coefficient of friction between tires and pavement is much higher than the dynamic coefficient of friction. (That is to say, a sliding tire has less traction than a rolling tire.) Second, unless the vehicle's weight distribution is just right, the rear wheels will lock up sooner or later than the front wheels, which means you can't get maximum friction out of both front and rear brakes at the same time.

But stopping distance isn't the point. The real question is "are you safer with or without ABS?". A study done by NHTSA came to the conclusion "four-wheel ABS has essentially zero net effect on fatal crashes, but significantly reduces nonfatal crash involvements". So you're much less likely to be in an accident with ABS, although you're equally likely to die in an ABS versus non-ABS equipped vehicle.
