ok so i changed my brakes and i put them on so i drive my car and when i stop it shaes like crazy and then so i decide to push it harder and like my car goes to the side when i push the brake harder what could it be it feels like if one tire is braking harder than the other how do i fix that and the shaking

 

Check to see if your rotors are warped. Also bleed all of your wheel cyl.

 

this question is kinda stupid. obviously you didnt bleed the breaks good enough or theres something wrong with your lines. the shaking is cuz the rotors are either warped or just suck. or you didnt put them on right.
