Lately my cars been shaking really bad when I step on the brake. I can't even hang on to the steering wheel when I make an emergency stop. Sometimes when I'm braking and turning, it seems like I can't complete the turn. I've check the wheel and it's properly tighten and the brakes squeeks but it's really minimal. What could be the problem? Thanks for any help.

FYI, it's a 95 intergra, stock
