oh, I guess you haven't then

well the mech were supposed to check brake fluids during the check up!!

yep, I always check behind people who mess with my car, I can't stand letting anyone work on my car without me present. Even when I have tires put on I make sure I am in the shop when my car is.

Hopefully they did check, or if you didn't want to spend too much money hopefully they didn't

This prolly wont help u but i had a problem somewhat similar problem. I was trying to get up a snowy hill and my tires were spinning (3,000 ish rpm in 1st) and rite at the top (wheels still spinning) my anti-lock light on my dash came on and wouldn't go off. so i shut off my car and turned it back on, nothing happened. I was pretty worried so after awhile i started my car and headed home. On my way home I wanted to test to see if my abs was malfunctioning and slammed the brakes in the snow, to my surprise the abs worked and after i stopped i looked down and it was off and hasnt come on since

That's normal, though. ABS often freaks out on snow.

Something else that I can't believe I didn't mention. If the problem happens when you're going 160 km/hr.... then don't drive 160 km/hr.

Actually it's about 100MPH. I've been well over that speed so I'm not going to rag on him, just thought I'd let you know what the speed was though.

the funny thing is.... when i brake hard in the snow..the abs braking system goes off..however i never see the abs light actually light up...

Because the ABS light only goes off if the system is malfunctioning, I think.
