^^^lol

In all seriousness peter you will probably find your actually locking the rears as you smash the pedal hard and a violent weight transfer occurs. See aarons post for how to brake properly..

Other things to consider, its harder to lock a tyre the faster your going and your brakes are only as good as the grip a tyre offers.

Now think about what you said about guys on a track, more often than not a lockup occurs deep in the braking area due to not releasing the pedal enough, rarley does it happen in the initial part of the braking area.

It is completley normal to feel some feedback through the pedal while abs is doing its thing. Triton does it to me all the time, thinks ive locked a brake when I downshift to 2nd at 70k's in the rain.....weeeeeee

this. The ABS kick in my F6 is exactly the same in my mate's STI, same in my old XR5, GTI, ancient E34 bimmer... feels like the front of the car is scraping the road and the pedal sinks and then kicks abruptly. Better tyres will mean you can brake a lot harder before ABS has to intervene.

I run eagle f1 asymmetric 2s....not exactly cheap rubber.

I understand the pedal sensation is normal, and the dipping, but I guess the bit that shocked me was the clunk kinda noise. Like maybe the pad moves in the caliper funny...maybe sticky pistons? (and yes I read that the abs process involves the caliper pumping so to minimize lock up?). I'm sure im being crazy and still haven't gotten an expert opinion...but 95% sure its normal and I'm just crazy.

Its one of those things I dont know how to explain properly...plus only done it 4 or 5 times. I rarely get in those emergency situations on purpose

Now stop bumping this thread till I confirm my stupidity....I better send Dags a PM

When I did the defensive driving course at AHG (free with buying the Falcon and being under 25) they wet down the course and got you to lock it up from 60km/h. Felt like the entire front of the car was tearing apart at the time, but it's normal.

yeah the clunk is normal. I describe it as a sudden grinding/scraping noise with a distinct kick on the pedal. I'm not sure what exactly causes it, probably the hydraulics releasing pressure suddenly and the ABS system starting the automatic modulation. I've hammered the brakes enough times to know it's normal. If it indicated a problem with my brakes, I'd have put the car into a concrete barrier by now.

I've just got braided lines and new 660 fluid in, did a quick brake check to test the pedal firmness and managed to overcome the grip in my nitto invos almost immediately. It doesn't take much on street rubber. My NT01s hang on way longer on track.

Peter I dunno about expert opinion but a few people that have commented have been thrashing cars for a long time, some without ABS I imagine. I can recall having my vn ss dancing hard on the way into a corner, having the feather the brake treading a fine line between making the corner and going straight ahead. I also remember locking a brake to much and looking for a bail out option. Aaron is pretty handy at the wheel from what I hear, Tochii and furiousgibbon have tracked falcons regularly. The other that have commented im not sure but I imagine theyre not pelicans....

Experts maybe not, well informed, I think so. The overwhelming majority say ITS NORMAL BRAH.

Lay off the meth karnt, u and kokentoe....
