hi guys, just a quick question to all the octy owners who've had ABS kick in on them... when it kicks in i think that my brake pedal is actually rising an inch from where it was depressed to cause it to kick in. is this normal? having never had it before its quite disconserting to try emergency brake to have the pedal "lift off" of its own accord. whilst the abs is working it also appears to be impossible to depress the pedal further, is this supposed to be the case?

i hope someone understands me out there?

air trapped in the abs hydraulic unit???

i dunno if anything is wrong or (and its probably this) im unfamiliar with the sensation of abs, i mean it stops like nobodys business anyway just curious inquirey.

Never done a really hard break in my vrs but in a seat v5 i had a couple of years ago the abs used to make the pedal vibrate to calm you down, not sure if your car uses the same idea

when it did it the first time after thinking i dmamged something i looked it up in the manual and it explained it and the reason behind it etc

Calm you down? You're having a giraffe surely??? Its nothing to do with the modulation of the brakes going on and off and you're feeling it back through the pedal then???

Ha ha best laff i've had for ages!!!!!!!!!!!

yea i didnt calm me down when i had it happen to me in the snow

I seem to remember that when ABS first came out, it lead to an INCREASE in accidents, as people jammed on the brakes, felt the pedal vibrating, thought, "What the hell's that!?!", took their foot OFF the brake pedal, and drove merrily into whatever it was they were trying to avoid! :(

One of the few occasions where 'consumer education' might have actually been worthwhile (thinking about these off-road courses Land Rover drivers get offered when their new purchases won't ever go near a muddy field, let alone a pile of logs or a giant see-saw )

Having tested the ABS "properly" (with a genuine emergency on snow), you're going some to set it off in the first place, but it does kick back a touch when it does. It's a vibration from the valves cycling, not any form of "pedal pusher" though.

I think its probably better to turn off your abs in the snow, drive smothly and try to avoid the brakes altoghether.

My ABS is always going off when braking firmly in the damp and driving over manhole covers or other slippery objects. I find it comforting that when one wheel has slipped slightly, in the space of a couple of feet the car has recognised this action and already correct the skidding wheel by modulating the bake line pressure to the offending wheel. It is a marvellous invention.

Most new cars (a la Octy II) have Brake Assist anyway, which detects panic breaking and applies maximum pressure almost instantaneously. I think it

I think its probably better to turn off your abs.

you cant! hth:D unless you take the fuse out

i though that they had got rid of the fuse trick??

Just for errrrr diagnostics what number fuse would it be?

completely agree with that. when it snowed not so long ago, i just turned the traction control off and took it very carefully. just as i turned the corner into work the front lost all traction so i yanked up the hand brake in a sort of panic but it kicked out to the side, i took it off again and proceeded round the corner quite normally. i was well shocked to say the least. but it worked!!!

back on subject though, the judder through the brake pedal is the pressure changing via the modulators. its perfectly normal for an emergency stop/ skid.

Personal comment. I just find it worrying but not surprising that when people get a car they dont take it out and practise an emergency stop to get to feel how it behaves when you do this. ABS can save yours and others lives but only if the driver knows what to do with it when it becomes active. Its no good thinking whats that funny vibration in my right foot as you crash into the object directly in front. ABS does have limitations based mainly on tyres, the vehicle dynamics and road conditions, but too many people think it will somehow save them by magic and when it starts vibrating they panic and release pedal pressure. Thats why newer cars have emergency brake assist to keep the pressure on and use the ABS to its max advantage. My daughter is 17 next week, shes been driving my old V8 90 around fields for a few years now but she will be practising emergency stops in car very soon until I'm confident about her abilities. Also ABS keeps your tyres round.
