2000 Silverado brakes quit working on rough asphault!

[CN Spots]

As much as I love my truck I have discovered a lethal flaw dat needs fixin. There is a patch of road that I drive on everyday that has a washboard distortion to it, not bad but on more than one occasion, while braking hard the brakes seemed to give out. I can't think of a better way to describe it. Something up front made a humming noise and I lost about 75% of my stopping ability My guess is that the anti-lock got fragged from the vibrations. Anybody else run across this? Thanks.

Yes its probably your abs coming on. I don't know about the new chevs but the older ones had that exact problem your talking about. It was like the factory made them too sensitive.
There was an icy spot right in front of the chev dealer and it was fun watching them try to stop before going into the cross traffic at the inter section. Then thay would have to explain to the customers why thay just about totaled there vehicle.

And it's not just chevy either, I had a ford xlf250 that did the same thing, the rear tires would (without a load) bounce off the ground. the computer would release those wheels. It is not a good feeling blowing through a stop sign you thought you had time to stop at I have talked to several dodge owners that say sometimes they push the brake pedal and nothing happens! That could explain why I see so many bent dodges,,,,

Well, at least it's not in my head. What engineer thought anti-work brakes was a good idea?

There was a TSB on that ...the seal at the sensor allows water =salt in re-seal usually fixes the problem....also good time to do a complete bleed ..get all the water out of the fuild...it destroys Ford controllers and not so good for others

You know ive thought about that. If you know how to drive you don't need them. In my opinion I think you can stop faster and safer with out them if you know how to use your brakes correctly. But with them any one can brake safe. I guess its the difference between knowing how to drive and just driving the automobile.

It goes against everything your body will tell you, but the quick fix is to release the brake pedal. I had a '99 new body style that would do the same thing over railroad tracks. A quick pump of the pedal would get past the ABS and allow full brake pressure.

In reality, there's nothing inherently wrong. The truck suspension allows the wheels to bounce, slamming on the brakes causes the lightened wheel to slow, and the ABS kicks in. The issue is the timing since the ABS doesn't work as fast as the wheels are bouncing up and down.

You know the road, you know the truck reacts that way, don't put yourself in a position to have to slam the brakes at that point.

I don't think the TSB for the wheel sensor causes the problem you're experiencing. If it's the one I'm thinking of, the wheel sensor goes bad, throws a code, and the ABS just doesn't work. Different issue than you are experiencing.

ABS isn't designed to "stop better" in all situations. It's purpose is to allow a wheel to keep turning, theoretically allowing the driver to maintain traction and turn to avoid a collision, instead of locking up the brakes and skidding.
