Okay, under hard breaking I have to hold the steering wheel straight. My friend said it was the road, cause you know sometimes at the Stop lights there are grooves where the car tires have worn . I can kinda understand that but it's not always like that everytime I break.
I was thinking that the pressure wasn't equal from the left and right and or perhaps there was air in the lines???
Any others with this problem or other suggestions? Remedies?? Let me know

thanks in advanced
