    Anyone else think it kicks in too early? or is it just me?

    i was coming home on some brilliant windy b roads, got a bit carried away like and was heavy breaking into some corners, it was bone dry, fairly grippy roads, and it kicks in. I felt that it could've braked a bit harder, or maybe i was gettin the max outta them, as we all know they're a bit poo.

    i was also thinking if i replace discs and pads for some such as grooved ebc and ferrodo pads for example, it will break a bit harder and possibly break grip sooner, meaning the abs will come in even earlier!

    what are peoples thoughts on this?
    should mine come in so early?

    I must say my i've only had my abs kick in once, i had to do an E-STOP when some F**ker pulled out on me.

    I've got EBC Ultimax Disc's and DS2500 Pads and seems to be fine.
    Like sportstractor said it could be tracking.

    I can't believe nobody has said this yet, but it sounds like **** tyres to me!

    The more poor your tyres the easier it'll be to lock up the wheels. I'm able to slow down quicker than any s3 on 312's with my Porsche brakes and toyo t1r's, but the abs very rarely kicks in at all unless you're being VERY stupid.

    I have black diamond discs and ds3000 pads and my abs rarely comes on.

    Picked my s3 uptoday from 4 wheel alignment and it feels so much better, much more stable etc. Worth paying for

    Good point J, your 312's with ds3000's were definitely the best 312's I've ever known

    I can safely say i have never had my abs come on but that may be down to A, good tyres B, turbo groove disc's and DS2500 pads

    I'm thinking it could be the tracking then as the ABS light and the ESP light have a habit of coming on at the same time and I've read that can be a cause other than the longtitude sensor!

    well i've got bridgestone potenza re050 all round, they seem alright, not very good in the wet but in the dry they hold the road quite well. they are coming to the end of there life though, took a fair bit of stick at the ring but served me well indead! so maybe that contributes to it. Il have to upgrade my discs soon enough anyway so il get pads too and see what happens then. ds3000's you say?

    i've not had abs for a while, put a new longitudinal sensor in yesterday and it definately works now lol.

    scoobyra as i just said the sensor fixed mine, only my esp still doesnt work due to a awd fault. have you heard alignment can be a cause too?

    Don't know what suspension you are running karl, but knackered front shocks can cause early ABS kick in also. My S3 stopped with no ABS kick in on a bumpy road when I had my Bilsteins fitted, on standard shocks, the ABS would kick in if I braked hard over uneven surfaces at speed.

    suspension is standard. although all round it does feel quite tired. i was planning on new bushes all round, top mounts too. but new suspension will have to wait. but thanks that does make alot of sense.

    I run standard suspension and standard brakes and can honestly say I've never had problems with the abs kicking into early, only time it may kick in is if I jam them on to come to a complete stop especially n the wet,

    Brake fade is the biggest problem with constant heavy breaking,

    When I first bought the car it was sitting on crappy budget tires and I still never had an issue...

    Your ABS system cutting in a bit earlier than usual is likely to be down to your tyres wanting to slip under breaking. Could have poor tyres which cannot which stand much loading under braking or your tires are worn past there best.

    The ring has killed them lol, all in good fun though.

    What are RE050's like as I have been meaning to try a set. Whats the grip and feedback like and whats the wear rate like on them.

    well i wouldnt get them again. dry grip is good, holds well and you get pretty good feedback, you know how much grip you've got left etc. as for wear well they seem ok, they're not that high on the 'sport' spectrum if you know what i mean so the compound is fairly hard compared to some. What lets them down is wet weather. I did some research after i got back from the ring, where i span in the rain, and they do pretty badly in wet weather testing, aquaplaning was a massive issue, and all that feel just dissapears.

    my next tire of choice is the falken fk452 i think. my mate has them on his golf, although front wheel drive, the grip is amazing, even in the wet, a little softer than the re050's. so wear faster. but they should inspire alot more confidence than the bridgestones. i hope.

    Tyres & also check the abs rings on the driveshafts are clean and not damaged as this can send incorrect pulses to the system.
