    ABS and snow do suck. The bypass mod is helpful, but I would recommend not overlooking increased following distance and engine braking.

    Sometimes, in slippery conditions, you don't have any brakes, regardless of what system is installed on your vehicle.

    All true

    it's also true that ABS INCREASES stopping distances on snow

    It's tough for an auto maker to include systems for every climate, you guys get snow and ice while some of us never deal with it. I feel for you guys but am grateful the stock system works for us in the warmer climes. Good luck finding a work around.

    ABS increases stopping distance in any weather.

    ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers; however, on loose surfaces like gravel or snow-covered pavement, ABS can significantly increase braking distance .[1]

    The semicolon was the giveaway. :D

    Check this out, from the same page:

    "In gravel, sand and deep snow, ABS tends to increase braking distances. On these surfaces, locked wheels dig in and stop the vehicle more quickly. ABS prevents this from occurring. Some ABS calibrations reduce this problem by slowing the cycling time, thus letting the wheels repeatedly briefly lock and unlock. Some vehicle manufacturers provide an "off-road" button to turn ABS function off. The primary benefit of ABS on such surfaces is to increase the ability of the driver to maintain control of the car rather than go into a skid, though loss of control remains more likely on soft surfaces such as gravel or on slippery surfaces such as snow or ice. On a very slippery surface such as sheet ice or gravel, it is possible to lock multiple wheels at once, and this can defeat ABS (which relies on comparing all four wheels, and detecting individual wheels skidding). Availability of ABS relieves most drivers from learning threshold braking."

    +1 here 2012 O/R TRD with OEM tires - did fine today in the snow. Was in 4x4 most of the time, turned it off for a bit in a parking lot so I could understand how she handles when the ass end lets loose.

    There's been some speculation that the OR's ABS may operate differently than the others. There are differences in the brake system due to the use of A-TRAC on the OR, so it's possible.

    I hope you see enough snow and offroad use in the Tacoma to make up for the loss of the M3. Those are some mighty fine cars.

    Not at all, hence the :D. I wasn't implying that you'd done anything wrong. My apologies if that was your inference.

    I'm not disputing any information given in this thread, I hate the ABS in the snow just as much as you guys do. It feels like it never lets go, or pulses like other systems do... BUT

    In low traction conditions, you guys should really consider 4WD and downshifting a gear before ever touching the brakes. When you're in 4WD and you downshift, stopping power is essentially 50/50 between front and rear axles. When you step on the brakes its more like 60/40 front and rear, respectively. Its much easier to brake the tires loose by using the brakes than downshifting.

    Drive safe, as you always should. When approaching a stop, downshift 1 gear, down two gears is acceptable if you're not bringing up the RPM's above say... 3,000 rpm. Lightly use your brakes to increase your stopping power, but you'll find you wont to use them as much. I've been able to stop much faster this way without triggering the ABS.


    Food for thought. I may look into this ABS kill switch for winter though, but in the summertime it has saved my ass once.

    My '06 DCSB base with the vaccuum booster is way oversensitive on snow and ice, I don't think its just the Sports. Decent tires help a lot, as do driving to conditions. Replacing my base tokico shocks with TRD billies helps some too, more on bumpy roads. That said, this ABS system doesn't seem to allow enough % of slippage to give any braking once it engages. It even engages at less than 10kph, where its of no real value. Compared to other modern ABS equipped vehicles I've driven without issue, I've found it downright scary a few times. ABS is indeed designed to give steering (directional control) priority over braking, to allow the driver to avoid a crash by steering around an obstacle, but it should modulate threshold braking at the same time, something that doesn't happen well in my experiences. Installing the disable switch was one of the best mods I've done on my tacoma, as I often combine snow and "off road" driving. And, with a flip of the switch, I have it enabled again for safety at higher speeds on road.

    There is no opportunity to utilize threshold braking at all

    Nods! Sometimes you have four tires, and sometimes you don't.

    Another note about ABS: It isn't neccesarily designed to bring your vehicle to a complete stop. One of its main functions is to keep your vehicle straight when you apply brakes - especially important when you are driving at speed.

    Impacting an object straight on with the designed crumple zone is better than an irregular collision at a slightly lower speed.

    Obviously the focus isn't on crashing your truck every time you hit the brakes in inclement weather...I'm just making an argument for why having ABS turned on at higher speeds is an intelligent choice.
