Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question and I will be posting your reply ASAP.

Hey how are you

1- usually the disc rotors will be warped from excessive heat from braking especially if used a lot down hill

2-does the steering wheel shake as soon as you apply brakes and the hard you press on brakes the more violent the shaking is ?

3- I would take wheels off and inspect brake pads & rotors and see if there any groves in them

Please let me know

Thank You

the steering wheel has done the shaking only a couple times when going down a steep hill even when i drop down the gears

there is more to it than just brakes, a sway bar bushing ,ball joints ,sway bar end links etc..

but if it is more evident i would say the brake pads & rotors ,especialy if you never done brakes on it

the trans mount and engine mounts also needs checking ,but when you have it raised on lift you can check all under carriage pieces

Please let me know if you need anything else

Thank You
