I'm trying to remember if ABS helps in snow.

Yes, but not on ice.

I can't remember not being able to brake on ice with ABS. |

So, on icy roads, if all 4 wheels (on a car) are locked the ABS assumes the car is stationary.
In that situation, and heading towards an immovable object, it may take great inner courage to remove ones foot from the brake pedal and pump repeatedly.

Even with ABS I cadence brake without thinking about it. Comes from years of driving cars without ABS or even much grip to speak of.

Yep, I do the same in bad winter conditions.

No amount of cadence breaking affects the grip of a tyre. Cold hard compounds grip less than cold soft ones. Just about nothing grips polished ice like glass. But most real Road ice isn't like that, so things like tread depth and pattern and rubber compound affect braking ability. And good abs works for the same reason. All 4 wheels rarely lock instantaneously together on real Road ice

Been looking at sets of winter tyres, Nokian WR A3 looks good.

Agreed. On ice, it can regain control if you're fast enough, since ABS can go brain-dead in those circumstances.

My Volvo has an outside temperature display, and at (and below) 2/3 degrees C it shows an icicle, so warning of possible icy conditions.
I assume it is common on modern cars ?
Also my auto box has a snow setting which disables 1st and 2nd gear, so starting in 3rd using the torque converter to limit power to the wheels. It really works to limit wheelspin on ice and wet grass.
I know it can be done with manual gearboxes, but I hate slipping clutches.

Yep, my ice warning shows at 3°C and I put my auto box into manual 2nd to pull away.

Thanks Is that the Mondeo floorpan jobbie ? Estate available too which is on the list of needs Auto might also have to be on the list too She'll love AWD The Freelander 2 also uses the same floorplan. |

Just how often do you get to test your cadence braking against the abs? You can't turn it off and do 20 a:b's. Either way - it's no substitute for good rubber. Your tyre is the only component in direct contact with the road surface. Good ones are priceless |

Lots of times.I come from Braemar, in an area of the Cairngorms that gets the worst winter weather in the UK. I have a lot of experience driving on snow and ice.

There's a bad spot on my daily commute into work in the mornings, that I get to at about 05:40. Of a cold winter's morning, a long stretch of it can go to black ice. More than once I have felt all grip go - you know the feeling, steering goes light and no directional control. I have braked and felt the ABS go stupid, but I have then backed off, reapplied and repeated and managed to slow down enough to regain control. It's not exactly pumping, that's too crude. But you can feel through the pedal, despite ABS, what is going on at the wheels. |
