    I guess you missed this:

    What does a dealer or two say about it? Have you had it in for service, or are you just ranting?

    Well I have idea why dont you let your wife drive your Tacoma?
    Or better yet show us how you can steer around traffic with no brakes on busy intersection after your blow red light. Drain brake fluid hit intersection and show us how you steer around cross traffic. :rolleyes:

    Actually when I had my ABS issue a couple times; I couldn't even steer the truck to make any kind of turn, it would only go straight. It's literally like you are floating on top of the surface of the road in slow motion when it happens.

    To clarify, are you saying that when you turned the wheel, the truck would not turn, OR that you were unable to move the steering wheel?

    The ABS issue has happened to me twice on the road, and once I didn't try to turn because of oncoming cars. The other time I did try to turn, and was able to turn the wheel, but the truck would keep going straight while the ABS was going off, as if I was just floating on top of the surface of the road no traction at all while ABS was hammering away.

    Also, both times when this happened to me the ABS kicked on and would never kick off until the truck finally came to a complete stop, even if you left off the brake for a second and then went back on the brake it was instantly still in ABS mode with not even a second of delay before it started back up. I've never experienced anything even close to that in any of the other ABS vehicles I've owned.

    Although I have not experienced any unusual ABS actions, I will say this thread his made me more aware of potential problems with the ABS in adverse weather and likely increased my caution when driving in such conditions.
    Thank you to all contributors!

    Again, this seems like a tire issue. A tire that is "floating" should be free wheeling and able to steer. If it's not it's a problem with the road contact patch. Again, I'm not saying that snow tyres will fix your ABS problem, but it's the only thing you can change easily right now to allow you to deal with the situation better and hopefully gain a little bit of braking back while at least allowing you to steer.

    Otherwise you disable your ABS and VSC. If that doesn't bug you have at her.

    She does drive my Tacoma, lots, soo..... :notsure:

    I'd rather enter that intersection with no brakes and the ability to steer than neither. That's what I was trying to say. What happens if you have the green and another guy blows the red? Neither ABS or good ole' BlueT's threshold braking mastery is going to stop you in the 50-100 ms you have before impact. However that flinch reaction reaction of hitting the brakes (and deploying ABS) combined with the ability to turn the collision from a 90 degree impact to a 45 degree impact dramatically reduces the chances anyone is going to die. Period.

    We could go for days in this circle lol.

    I can tell you right now it's not a tire issue, I don't care what it "seems" like to you. Until you have experienced it for yourself, you will have no idea what we are talking about. Am I going to change my tires in the near future, yes. Do I think a tire with better traction will help, yes. Is this issue completely related to tires, hell no!

    I'm certainly going to install the disable ABS switch also, so that I can flip it in the middle of the ABS issue happening when/if it happens again in the future.

    Will 285's have an effect on the ABS on this trucks?

    Your Tacoma is made in Texas. How do you expect them to know anything about stopping on snow or ice, with crappy tires, and an uncalibrated VSC?

    Yes. The friction coefficient changes in proportion to the operation angle of the treadle valve actuation dampers motor inertia springs.

    I never said that the issue is 100 percent your tyres. For the last time, I said Winter tyres will allow you to steer if your tyres are rotating at the same speed as the pavement, which is better than no braking and no steering for most people. Hell, maybe with better tires you'll even stop a bit faster which would help wouldn't it? Take some pills :thumbsup:.

    So, I'd need to recalibrate the PSI threshold on the treadle valve or the inertia springs? How many degrees variance is within OEM specs on the operation angle, do I need to calculate the atmospheric density at 0*c vs. compression ratio at 32*f?

    The inertia springs are coil, so no PSI adjustment required. You have to re calculate the rotational mass added to the un sprung mass of the vehicle, then add the correct amount of corresponding frictional surface area to the vehicles retarding devices.

    I would divide the sum of the masses by the product of frictional area and the coefficient of friction. That way, using the ratio of frictional surface radius to frictional area radius the inertia could be modulated at a rate proportional to the angular velocity.
