Steering wheel and brake pedal pulsate when braking...?

I have a 99 mitsubishi eclipse.The faster i brake in my car the more the front end of it seems to shake as well as the steering wheel and brake pedal shakes. I looked in my haynes manual and it doesnt say much. I just changed the outter tie rod today bc it was blown. i do know i need an alignment now but beside that my front end is still doing the same shuttering when i brake. Could it be the wheel bearing?something else? also my rotors are fine but i do need to change the drum brakes but that i dont think has any thing to do with it but throwing it out there. any ideas would be great thank you!

You have a very common problem. Your front brake rotors are warped. The fact that it only does it while your braking and that the steering wheel shakes is a dead bang description of this. A good shop will check the rotors using a micrometer to measure the 'run out' and repair this accordingly by either turning the warped rotors on a lathe or replacing them with a new set as well as making sure the rear brakes are fine and verifying the repair with a test drive.

Notice %26quot;only when i brake%26quot;.

You have one of the following.. warped rotors, and/or, your calipers slide

pins NEED to be greased, because their supposed to be able to %26quot;float%26quot;,

when they dont float only one side of the pads gets pressed against the rotor, that

causes a pull first of all, and uneven brake pad wear. pulsating is warped/ out of round

rotors.. ABS does pulsate but only when your on limited traction surfaces.
Could be a few things. Warped rotor, bad master cylinder, bad break booster, if it has power brakes. That's why everything would %26quot;shakes%26quot; as you apply the breaks. I doubt it's the alignment that would cause that. Not when you brake.
any time you change steering parts you need a wheel alignment and now what you need is either new brake rotors or have yours resurfaced as they are heat warped and causing the shake when you brake.
