hey i just recently replaced my brakes and rotors and now everytime when i hit on the brakes the hole front end shakes violently, i do not know what it is everything is fine when driving nice and smooth, but soon as you are to hit the brakes the vibration comes back and goes away when u let off the pedal. please help me.

 

You're rotors are warped. You might have over tightened the lugs on your wheels and warped the rotors. You should have also cleaned the surface of the hub to make sure the rotor sits flat.

 

I have a feeling the 2 rotor screws came off or either you forgot to put them in.

 

The you don't really need those screws. I would check to make sure the rotors are properly seated against the hubs.

jack the front up and before you take the wheels off move the wheels around to see if you can feel which wheel is warped. they will always drag a little but if its as bad as it sounds you should be able to feel one wheel drag a lot as you turn it. there should be a constant resistance as you turn the wheel, if it goes from easy to hard to turn as you turn it, something is wrong.

 

The screws are only there for ease of installation when putting th brakes back together. I personally don't have them or feel the need to.

 

i fixed the problem, the screws that holds the rotor on the end, ended up strippin out so i had to drill it out so i can get the rotors off and i neder took the rest of the bolt out so after i realized this the rotor was no were near flat on the hub so i took it out but everything back together and it runs smooth as a babies a$$
