    Sensitive ABS

    Does anyone find that their ABS kicks in a bit too easily? I think mine does, unless it's just crap tyres (Nexens. i've never heard of them, but the garage replaced all 4 before i picked the car up when i bought it, so probably cheapo ones?) My previous car was a Pug GTI6. I thought the brakes on that were quite good. In the dry, you could quite literally stand on the pedal and it would stop without a flicker of the pedal. But in the Astra, even in the dry, too much pressure and it starts to kick in, and judder. I just think that it's letting the brakes down a little. And i don't see the point in upgrading the brakes, as then it'll just lock up easier, and the ABS will kick in quicker.
    Any ideas?

    Could be the tyres. I've zero problems with the ABS on the Astra. Now, the Corsa C I had was a different matter. The ABS went off if you looked at the brakes.

    Are the tyres the same size front & rear and at the correct pressure?

    Sorry if this is teaching granny to suck eggs! The reason I ask is that the only ABS problem I've had related to running different radius tyres front & rear during a phased changeover to slightly larger diameter tyres. This confused the ABS electronics so that it operated nearly all the time. Restoring equal radius tyres front & rear eliminated the problem.

    Don't think I've ever had the ABS going in the coupe and I drive like a complete tool.

    I've often thought mine kicks in a little early too. Your sure theres a little more grip left, but then it kicks in. I'm running Eagle f'1s all round so its not the tryres. I may just be wrong and the wheels might be starting to slip, but I dont know if I like it, It seems to take away a little of the stoping power. I used to be pretty good at feathering the brakes on the verge of lockup on non abs models. Then again, I'm not complaining, Sooner or later that ABS might just save me.

    Come to think of it, I'm sure I read on vx220.org that some people had changed the electrical module on the top of there abs block/pump that give you less agresive ABS, it might of been off a vxR220.

    If so, it wouldn't kick in as easily as it would be less aggresive.

    I find mine comes on if I brake round a high speed corner.... Now I know you shouldn't be braking round corners but sometimes your forced to! None of my other cars had this problem and it really makes the car unstable i've got a gsi with eagle f1's all round.
