Ace of Pop Posted November 29, 2013 Share Posted November 29, 2013 On a Dry Road does A.B.S extend the breaking distance over an identical Car without it.?. Link to comment Share on other sites More sharing options...
stevenl Posted November 29, 2013 Share Posted November 29, 2013 Depends on who is driving the car. For many drivers it will decrease the braking distance, for the exceptions that can brake without ABS exactly to the anti blocking point it will decrease the distance.

tom21 Posted November 29, 2013 Share Posted November 29, 2013 with ABS you can steer the car when braking heavy. that is all you that matters 1 Link to comment Share on other sites More sharing options...

There will be very few exceptions in the case of an adrenaline charged panic stop! The main point is consistency and control [steering]. 1 Link to comment Share on other sites More sharing options...

There will be very few exceptions in the case of an adrenaline charged panic stop! The main point is consistency and control [steering]. Even the best drivers in the world can easily lock their brakes under extreme braking, you just need to watch any F1 race to see that. As tom21 says, once you've 'locked up' you lose steering ability, you also lose lots of stopping power depending on the surface. Without ABS 'cadence braking' is the only way out of this. ABS in most cases will improve heavy braking ability unless you're name is Vettel or Alonso Link to comment Share on other sites More sharing options...

Ace of Pop Posted November 29, 2013 Author Share Posted November 29, 2013 I was thinking, 2 Identical Trucks , side by side at say 130,both stand on the brakes,i recon the non abs would get the edge but would have flat spotted the 2 front tyres.Not sure,thats the debate intended.

WarpSpeed Posted November 30, 2013 Share Posted November 30, 2013 (edited) with ABS you can steer the car when braking heavy. that is all you that matters Yes but a skilled driver can threshold brake and steer and then lift to steer at the optimum timing if the tires loose traction by exceeding their maximum grip and provide a quick direction change if you need to take avoiding action.

Actually they're not in all cases, not all teams run the same pressures nor do they always run the same temps produced by those temps, a lot of factors go into grip levels versus tire wear it's no so black and white, that's one of several differences between the front runners and the back markers...

Actually Yes and No. I'm not saying they are not factors but I'm assuming tyre compound, tread pattern, pressures suspension & chassis stiffness etc,etc would be the same for an ABS and non-ABS example. I'd also agree that with a concentrated, skilled driver he'd probably have the advantage over the best setup ABS configuration. That's why compeition drivers mostly disable ABS on cars equipped with it when racing. However, the average somchai in his pickup has never heard of 'threshold braking' and would have little concept of what it means or how to avoid locking his brakes. So in most situations for most drivers, ABS will improve extreme braking (and car control), otherwise why would it be an option ? I think I'm a pretty decent driver but I know ABS has saved me a few times especially on damp/wet/slippery surfaces. I've also noted sometimes ABS kicks in prematurely so it needs to be setup correctly. The OP subsequenty posed the question if he 'stood on the brakes' which is better ? In that case ABS no question. 1 Link to comment Share on other sites More sharing options...

Right but the OP doesn't distinguish from Somchai nor does it refer to Thailand and you used the example of F1 as well which is also what I responded to. Actually in most racing series the ABS is considered an unfair advantage especially in the rain which is uncertain as to when it may come or not? Additionally it can also be used as a traction control device so thus most series disallow them as the bigger teams have the money to make them more effective, this is why F1 outlawed it..

cooked Posted November 30, 2013 Share Posted November 30, 2013 In Switzerland before the days of ABS we were taught to rapidly depress and release the brake pedal to prevent wheel locking. It works in snow. I wonder if this would work on a car with automatic?On my last truck I had the ABS working three times, twice on the Expressway, avoiding a shunt, and once to avoid killing a dog. In 6 years. Link to comment Share on other sites More sharing options...

Ace of Pop Posted November 30, 2013 Author Share Posted November 30, 2013 O.K. Identical Trucks,same Geometry and Tires /Compound on a Dry Road , straight line from 125 to 0.. Whos the Winner.?. Il go for the non ABS........... Flat Spots expected, and rear tires adding very little to help the situation. Link to comment Share on other sites More sharing options...
Spoonman Posted November 30, 2013 Share Posted November 30, 2013 (edited) I reckon it will be the ABS model. If your flat spotting your tyres on the non ABS you are losing grip and as such are not slowing down.

transam Posted November 30, 2013 Share Posted November 30, 2013 The first car I had with ABS was a 1988 Volvo 760. The ABS feature really was a revelation for a safer ride. Previously I had three Ford Granada's, all heavy cars, drove a zillion miles in them and for sure the ABS really made a big difference in a sticky situation.
