ABS Explained.

just google braking distance without ABS and the first 2 pages already have many links to articles showing that no ABS can have shorter braking distance. Too many links to copy.

 

Anyway it still depends on the driver. I also saw many links showing ABS have shorter braking distance because no ABS the wheels lock up. So it depends on the driver also.

 

 

Since you already acknowledge that in your test(s) and here that the driver is the key criterion, why bother arguing that an ABS car will stop faster than a non ABS car?

If i am capable enough, i can similarly brake till the extent that i dont activate ABS on my ABS enabled car. How does this brake distance compare to your brake distance on your car without ABS (which you have braked without locking up)?

 

Already mentioned in one of my posts previously that it will be the same...

 

But the point is the stopping distance of ABS and non-ABS cars. If you don't activate the ABS then its the same as a non-ABS car. So whats the comparison?

I am saying a car without ABS can stop in a shorter distance... I never say will, I said can. Just stating that it isn't true that a car with ABS will stop in a shorter distance.

 

I agree ABS is good but the point is whether you can get a shorter stopping distance without ABS or not.

now you are contradicting yourself.

There is no contradiction. You just don't read properly. You asked if you braked till the limits of the tires before ABS kicked in. Isn't that the same as not having ABS? So whats so surprising that the result is the same as a car which doesn't even have ABS?

 

Or did you not understand what I am trying to say? Did I ever say that a car equipped with ABS will have a longer stopping distance? I have only been saying that a car without ABS can have a shorter braking distance than a car with ABS. Can, not will. This is because it still depends on the drivers. If the drivers both practice threshold braking and brake to the limits of the tires rather than just slamming down on the brakes, the ABS won't affect anything since the tires aren't going to lock up.

 

However if you talk about relying on ABS to get a shorter braking distance, then in dry conditions, a driver who doesn't rely on his ABS can have a shorter braking distance if he doesn't lock up the wheels as compared to another driver who slams down on the brakes and let the ABS do the work.

well you did state over quite a few times that a car without ABS can stop in a shorter distance wor. [laugh]

Thought Takumi got man made ABS for mountain roads?

 

It's not the car, it's the driver... :D

how many takumi are there in the world??

 

There are people who can run 100m in sub 9 sec does this mean it is the standard? [laugh]

there is a big contridiction.

 

first you say its the car.

 

now you say it is the driver.

you might not mean it the way we see it. but you cannot blame us. take a look at the following.

 

For certain cars I think its true that ABS off have shorter braking distance. Tested out with my car and when ABS off I get shorter braking distance.

This one imply that you are talking about car.

If you don't lock the tires you will still have control while doing e-brake and have shorter braking distance than cars with ABS. Just practice more. My car has no ABS and I haven't locked my tires since I started practicing how to e-brake. Experienced many times already. Once was on a wet road and the guy infront just ebrake till he stop cuz got ERP gantry. Just need more practice.

 

But I agree that ABS is useful if its snowing though. Quite impossible not to lose control in the snow without ABS and traction control.

 

Even for cars with ABS if you brake just till the point before ABS is activated, the stopping distance is shorter from what I tested. Once the ABS is activated your braking distance is increased already.

 

Here to. you specify Cars with ABS instead of ABS activation.. seems to imply that it is the car..

 

btw, apparently if you didnt lock wheel in snow, its should perform the same purpose if you didnt wheel lock. so i dont see what so useful about it in snow.

 

of course, kudos for this part, you did mention finally that if ABS is not activated then it got shorter distant.

Yep. The other car belonging to my friend had extra 200+km mileage on the tires. My car also had an extra baby seat so the weight might be different as well. Plus my friend was about 20kg lighter than me at that time.

 

Other than that we tried to keep the rest of the variables the same. Same model but different specs so his had ABS mine didn't.

you didnt tell us you are usinghard braking for no ABS abs Slam braking for ABS car. so we are assuming that you are doing the same brake for both.

 

there. this sum out what when wrong.

Try not locking your wheels in the snow. lol. In Singapore's kind of of weather still can.

 

Obviously if you are testing the braking distance of ABS equipped car and non-ABS car, you will want the ABS to kick in right? Need to tell you that before you can understand? If not whats the purpose of testing if both cars you brake without using ABS?

Why don't you read the whole sentence rather than just the part you bold?

 

Isn't that true? It can stop in a shorter distance.

 

Btw there is a difference between can and will. I never said a car without ABS will have a shorter stopping distance. I said a car without ABS can have a shorter stopping distance.

If this is how you are testing, then obviously you do not know how to do a proper testing on the ability of the ABS.

 

Like the name suggest, Anti-Lock Braking system. its suppose to be tested when both configuration are facing wheel lock stitutation.

 

if not, then you are not doing a proper testing.

yes you did. -_-

 

Had two same cars but one with ABS and one without. Didn't lock the tires. If you lock the tires then the car with ABS will stop faster and still have steering control. I braked without locking the tires and the car without ABS stopped in a shorter distance from 60km/h.

Did I mention I was testing under wheel lock conditions? Or you assumed?

 

I was just testing if its possible for a car to have a shorter stopping distance if you don't use the ABS. I wasn't testing the ability of the ABS. I did not even test if the car is still in control. I was only testing stopping distance. Maybe I should have mentioned that.
