For some reason when i am driving (all of a sudden happened went on brake and drove around car was fine and after work it happened) and press the brakes the brake pedal makes a grinding noise that u can feel intensely in the pedal fallowed by the sound of a pump once u let off, its only if u step on the brakes past a certain point like stomping on it, i can only slow down to the point of stopping then fully press the pedal, it got cold and snow outside randomly and might be the cause, thing is its not the pad or rotors because i'll turn my car off while moving and then hit the brake and the work like normal somebody please diagnose?!! ABS maybe?

First, re-write this post in English.

Second, check your brake pads/rotors.

If you are trying to drive in the snow and the possibility of losing traction is high then that noise is your ABS motor kicking in to help keep traction.

Pads and rotors are fine, I think minilogoguy18 has the right idea, we did get alot of snow in one day. When i turn off the car while driving the brakes work fine, turn it back on however it happens again and then the sound of a pump once brakes are let off. I'm sure there's a way to bi-pass the ABS on ludes, any ideas? pull fuse or unplug? thanks for the suggestions, as for the english part i musta been a little flustered when i typed it as it just happened and i wanted to get help quick haha

The noise of the pump is absolutely normal, let the ABS do it's job so you don't slide off the road.

ABS wont let put me use my brakes so i'm sure thats more likely to send me off the road. I'm just gona pull the fuse for it, brakes work fine when i'm not on snow, on snow they make unusual intense grinding sounds, like worse than grinding gears while shifting. and the pedal feels like i'm shoving metal through a grinder with my foot, thats not normal

I understand the pump sound is normal for a functional ABS, its the ****ty reaction before the pump sound is what I don't understand, i was just adding the pump sound detail to get proper diagnosis, I figured i'd visit the lude forum rather than google it and hear some kid say his cavalier has the same problem lol but my previous car had no ABS and i got used to it, i guess to buy another ABS is pretty pricey too which i'm guessing by the horrid sounds its making now is what i'd have to do, so in the mean time any ideas on how to bypass it? not remove obviously, just temporarily disengage it until i can get someone to look at it, and other than the ABS not working which would be obvious is there any other consequences?

I know i am triple posting here, but you might just be right this is my first year driving it in winter and I read that some cars just have harsher feeling ABS than others, my previous cars were a heck of a lot smoother i'm guessing maybe all the snow and slush might of dirtied up my sensors making it kick in alot sooner than it should,but other than that thanks for the help and if my previous posts sound abnormal for a prelude just post suggestions please
