ABS, is this a necessity?

[Fortress]

Certaintly...disengage the ABS ECU which is a MIL spec connector (probably wrong term). Not too sure about Japanese cars tho as they do not used such connectors for some cars. After disconnecting, it is just like your usual brakes.

Interesting. The article makes sense. So I guess it is better on wet or slippery roads in helping the driver to maintain control of the car then. But the stopping distance will b more on gravel or snow. Lucky we don't have much of that here.

 

But for wet roads, it sud shorten the braking distance by preventing the tyres from aquaplaning when the driver slams on the brakes.

 

I do remember seeing tests being done on cars with & without ABS on wet & slippery roads & the car with ABS stopped quite a distance shorter. Or were the tests rigged???

Quote" ...Vehicles equipped with braking systems without ABS have been shown to outbrake vehicles equipped with ABS. For example, the British car magazines "Evo" and "Autocar" conduct periodic tests of sports cars and compares their ability to accelerate from a standing start to 100mph and then brake to a stop

I was thinking that when u lock the brakes in water, the tyres push the water in front which makes it more likely to aquaplane whereas if the ABS kicks in, the tyre wil turn which helps to pump out the water in front of the tyre.

 

Hmmmmmm.......Now it seems the ABS is not as good as it was thought to b when first introduced. Something like air-bags. It has been discovered that air-bags can actually kill children if it hits them in the face. It only takes some real-life scenarios to reveal all these flaws.

locking the wheels is not called aquaplaning leh.. it's called skiddin rite? aquaplaning is even without braking ur tires floats n slips ard..

[Elfenstar]

even if what you thought was true, when we brake, the weight of the car shifts forward and theres more pressure on the front making it harder for water to push it up.

 

Especially with the advent of EBD, ABS would be safer in more scenarios for the average driver than a car without provided the drivers don't think of it as a miracle stopping aid.

 

As for thee airbags, take my mom's upcoming punto for example... the fromt airbags have sensors which adjusts their inflation power according to distance from the person in the seat, and in some older cars, the front passenger airbag can be deactivated should the driver require it.

For jap cars, just pull the fuse for the ABS controller. It will deactivate ABS and cause the ABS light on the dash to light up but nothing else is affected.

That makes sense. The grooves on the tyres are useless in dispelling water when the tyre isn't rotating. So if the wheels lock, the tyres will effectively be skidding on water.

[Fortress]

Not too sure about Jap cars, as I understand that if you disable the fuse, the ABS warning light will come on and it is irritating...too disable it, you need either physically removing it or, remove the ECU on it and make the main ECU to read that the car do not have an ABS. Then the light will go away.

ABS is useful for people who freeze like a cat during an e-brake situation.

 

often it's a less than 2 second thing... how fast you can pump the brake and steer away from collision manually?

 

 

it's actually a good thing to have ABS, I hope the govt enforces it, considering that there are many drivers who can't drive defensively in singapore.

 

just over last year i witness a few cars skidding across lanes and reflecting off the side walls like a pinball. i'm definitely for more safety features, so that other cars won't skid and hit me.

hey bro,last time when i drove a matrix,i tried very hard to stop,but still ski..Think got ABS or not is no different.Unless my one not working?

[Nothingtodo]

huh, u r the 1st person to tell me skid when e brake.... better go chk it bro

[Ronnie]

how fast were u going before u ebrake? skid when turning? did you stomp on the pedal?

right..... its strange Y LTA don't want to enforce it, make it a standard feature for SG rd, like Europe and USA. LTA always say they take que and reference from these continents.. but when it comes to some things... they keep quiet.

 

Just like rear passenger seat belt for e.g, they want to enforce on cars... because Europe, US, Australia, etc... already enforce it. However, they openly allow people to seat behind lorries, pickup without any restrain. No positive reason were given. I think this is very dangerous. When que on this, they plainly kept quiet... how else will SG drivers think and kept to its rear seat belt rules when TP half hearted effort and no power to stop people seating behind open trucks and pick-up.

========================

 

If u slam the brakes on a very wet road, the wheels slow down or stop turning which causes a build-up of water in front of the tyre. This build-up will cause the tyre to lift up off the road & this is aquaplaning.

 

U r right to say that wheel lock-up is not aquaplaning but it wil cause aquaplaning if the water cannot be pumped out fast enough.

 

What do u think causes a car to skid when a driver slams the brakes on a very wet road?

========================

 

I wud think a car skids when a driver slams on the brakes on a very wet road cos the water cud not b pumped away fast enough so it aquaplanes & skids? If it does not aquaplane, the tyre rubber is still in contact with the road & u still have grip.

 

This is the "fine tuning" manufacturers r doing to improve on an already good thing.

=========================

 

All along this was my thoughts on 1 of the main reasons why a tyre aquaplanes during hard braking. That's why ABS was invented to prevent this from happening.

If the light bothers u especially during the night, just put some sticker over it to cover it up.
