Why racecar does not have ABS?..

[eterna22]

simple, with ABS drivers cannot do late braking.

 

[Northiswara]

i ever drive ABS brake car and if u want to play emergency brake u better dun play larr. cozs the stupid brake is not so makan like the old normal brake.

 

[FVel]

I did find them (ABS) to be a factor in rain/wet conditions though....but that's just me. Other than that, most seasoned drivers (I'm not saying I'm one) tend to prefer non-ABS for the various reasons stated here.

 

[b00n]

sorry cos I'm lousy driver....I need ABS!.....hahaha
We're not driving in a racing circuit, every now and than you see pot holes, wet patches, some @ss suddenly cut in etc......
Yeah, I need ABS for all that....thank God my 11 year old car got ABS or else I guess I'll fish tail myself every now and than....

OK.....another fact, ABS is for emergency braking to swerve around the obstacle. Since one is on race track, why da hell he need ABS if he's going in circles around the track? Oh, just in case the car he's tailgating in front crashes so he can brake and controll the car to swerve out of the direction?! How many incidents are there as compared to normal driving?
It's not about racer don't use ABS as there's no need for it in the race track.

Even defensive driving course wouldn't ask you to take off the ABS. Just pure common sense.

Blackhowling
if i so skilled .. i dont need that old junk lo
not like you can take off and landing .. no need brake at all la


Overall it depending how you drive as well la

 

[Northiswara]

bro,

u all know what is ABS or not??
as the professor from junkyard i will explain to u what is ABS.
ABS is invented by professor junk in 1900.
ABS means AKU BRAKE SENDIRI.
ABS was first use by flintstone. u ever watch flintstone movie? he use his foot to brake his car. well that's ABS.

 

[Doink]

when u have racing with ABS on board
1.when u brake the brake wont jam...aiyo how to do last minute braking
2.when u race suddenly ABS lights turn on...aiyo masuk pit again
3.when u race then ABS relay rosak or short circuit...look for fire extinguisher
4.when u brake then come out new warning...AYC problem come out...

A detailed read and have highlighted the first important point in regards to this thread:
Racing Schools - Driving Tips - Antilock Braking - RacingSchools.Com

In my first braking article, earlier in this series, I promised a separate article on antilock braking systems (ABS). A recent report by the Insurance Institute for Highway Safety (IIHS) has raised questions about the effectiveness of antilock brakes and prompts me to follow up with this article.

Strictly speaking, antilock braking isn't a racing technique, since most race cars don't utilize antilock braking. There are two primary reasons for this: 1) It isn't entirely clear that antilock braking will reduce stopping distance for the skilled driver; and 2) Antilock brakes add system complexity, cost and weight to the race car, the disadvantages of which outweigh any possible advantages.

The IIHS report, issued December 10, 1996, notes that in single-vehicle accidents, cars with antilock brakes are as much as 44% more likely to produce fatalities than are cars without the antilock system. While the Institute declines to give a reason for this, it seems to me that the reason is simple and obvious. I don't believe that it indicates that antilock brakes are ineffective or dangerous in and of themselves. The problem is that stopping with antilock brakes, in an emergency situation, requires an entirely different braking technique than the one used with conventional brakes, and virtually no drivers have had or taken the opportunity to learn this new technique.

Different ABS systems work and react differently under extreme braking. While they all prevent the brakes from locking up, many of them generate pedal feedback -- pulses or bumps -- when they're working. They may seem to be pumping themselves; they may alternate between feeling firm and feeling soft; they may feel as though the pedal is going to the floor. The instinctive reaction for most drivers when they feel this strange brake pedal action is to reduce brake pressure, which deactivates the ABS, increases stopping distance and can actually cause a loss of control by upsetting the car's balance.

I said earlier that it isn't entirely clear that ABS will reduce stopping distance for the race car driver. It is very clear that it will reduce stopping distance for the everyday driver -- except perhaps in loose gravel or loose snow -- but that's not its primary purpose. The primary function of ABS is to enable the driver to steer the car while braking at maximum effectiveness. But steering in an emergency stop is itself a new technique. Abrupt or severe steering movements under these conditions will, again, unbalance the car and may cause a loss of control.

If you have a car with ABS you must learn to use it. ABS works and works well when you apply maximum braking pressure and HOLD it. DO NOT pump or ease off on ABS brakes in an emergency braking situation, no matter what they seem to be doing. If you steer while in an ABS stop, do it smoothly, but don't, under any circumstances, release or lighten your pressure on the brake pedal until your car is stopped completely. None of the above, by the way, applies to pickup trucks with rear ABS only, which should be driven as though they have no ABS at all.

It behooves every driver of an ABS-equipped car to unlearn his or her old braking habits and to learn the new ones that work with ABS. To do that, take your car to a safe location such as a completely empty and obstacle-free parking lot or a completely unoccupied street, preferably when the pavement is wet, and practice hard braking. Don't "slam" on your brakes, but press firmly, as hard as you can, with the force that would definitely lock up conventional brakes. Start at 15 - 20 mph and try to lock the brakes up while driving in a straight line. Your tires may screech or even skid or slide momentarily, but they should not lock up. If you can lock your brakes up, your ABS is not functioning properly. Stop your practice immediately and get your brakes checked and repaired.

No matter what the car or the brake pedal does in this practice, don't let up the braking pressure. Get used to what your ABS feels like when it's working; then do the same thing from 30 - 35 mph. At each speed, once you are comfortable with the feel of the car in a straight line, practice turning smoothly but positively while under maximum braking. Repeat this exercise several times, particularly at the higher speed, until you are completely comfortable with the way your car will react to a maximum braking situation and are confident that it won't surprise you.

ABS technology is expensive, and the more expensive the car the better the quality of the ABS system it is likely to have. There is a world of difference between, say, the ABS in a relatively low-cost Chevrolet and a top-of-the-line Mercedes. Both, however, require learning new driving habits.

Learn your car's ABS braking, what it feels like in your car and how it's different from what you have learned in the past. It is an exercise that can save your life in an emergency.

What does it cause? (ABS light turn on)

Antilock Braking Systems have come a pretty long way since its early days. Now its quite sophisticated, like a lot of other electronic safety/driving aids on a modern car like traction control and stability control. They really do work. Manufacturers spend tons of money and time to develop these systems after all. And they test it in the most extreme conditions (in Sweden on a big piece of ice basically) that you nor I will ever encounter here.

It is without question that for most people, they need ABS. To argue otherwise is to be an indescribably huge asshole.

Now for people who may want to indulge in more enthusiastic driving, there are a few considerations. Not all ABS are made equal. Most passenger cars are built with any level of driver in mind and therefore have ABS tuned so that it may cut in very very early. If it detects the slightest thing wrong it'll interfere. Which is kind of kill joy for people who enjoy a bit of hard driving. ABS found in more performance oriented cars may come with ABS tuned to be lazier and therefore interferes as late as possible, which is good since it theoretically allows maximum braking and only cuts in when a lock up is imminent and ideally that is what you want.

1.when u brake the brake wont jam...aiyo how to do last minute braking
.

Does late braking necessarily require you to lockup your wheels ?

 

[SentraVIP]

That's different kind of last minute braking. It's the last resort of braking before kissing the curb...

 

[FVel]

LOL Oh you mean 'that' kind of late-braking.

Well, I'm no racer, but in any case you might like to try this simple exercise out for yourself.

1. Find a large, long and wide open space of pavement, for example an large and empty parking lot.

2. Mark out your start line at one end, and put a traffic cone at the other end of your informal 'drag strip'.

3. In a non-ABS car, accelerate hard from the start line. As soon as you reach the cone, apply maximum braking.

4. Do two sets of runs,...one set is maximum braking without locking up your brakes.....for the other set, you slam on the brakes as hard you can to induce lockups. Measure the distance it took for your car to come to a complete stop.

5. Make an honest run everytime and I bet you will find that the panic brakers with their sliding and smoking locked wheels will require a longer distance to stop compared to the guy who did not lock up. That's my limited experience anyway (maybe I'm doing it all wrong)

WARNING :- Of course I take no responsibility if you decide to do experiments with your driving. You are responsible for your own actions and consequences.

 

[TitanRev]

My opinion is that some race cars don't have ABS is because,
1. To save weight. (as mentioned by most here)
2. Can show you how skill is the driver on braking because without any braking aid, the driver will have to use his own technique to control during braking.
3. Might cause more electrical or electronics problems since the cars are always driven under hard condition.

ABS is good considering most drivers are average people and not M.Schumacher.

 

[si|verfish]

Jamming your brakes and locking up your wheels is no good (in fact its the worst). Like FVel's excellent explanation earlier, it simply increases braking distance and control of the vehicle is lost (because grip with the surface is broken). Anybody who argues otherwise is arguing against physics. Making more noise and tyre smoke in the event of braking isn't necessarily stopping faster.

 

[Northiswara]

nowadays there each car manufacturer have their own ABS architecture. the way it works also differ from each car. afterall the car manufacturer wants to improve the car safety.

 

[escaflowne]

well, abs is great for normal road driving condition.Heck, it makes my life LOT MORE easier when there is an emergency.

Why racer dun prefer ABS? Just like silverfish said, the blardy ABS engage way too early and it just spoil the fun.In terms of safety, a racer can gauge how much i need to brake for this condition and how far i can go before i lock my wheels AND if i lock my wheels what i need to do get back the traction.

If we are talking about straight line emergency brake without ABS, manual ABS. It will not be as efficient compare to the ABS,but at least u wont skid right into something.

 

[vitrous]

hmmm...
i wonder..how to emergency brake without ABS?..
how to control the feet eh?..
please anyone give us more info...

and 1 more question..

cars like evo7, skyline have ABS or not?...(hehe..quite noob)..
