Feels like warped rotors but it's not
 

Any ideas guys..... When i use the brakes at high speeds my front end shakes. I just did my brakes last month and everything was fine. So i went and picked up another new set of rotors and it didn't change anything. i just dont have any idea what the hell it could be. any ideas would help.

Unbalanced tires
Tie rod ends worn

Also rotors right out of the box are not guaranteed to be flat/true. I always have mine trued up before I put new ones on.

you sure it's from the front and not the dreaded rear brake shudder all these trucks have?

i never thought about getting them trued first. i'll give that a shot. i haven't heard of a rear brake shudder? can it be fixed? I also noticed it gets worse the longer i drive. i would assume that the brakes are getting hotter at the same time? I just hit 51K with no issues now this starts. i hate to say it but i may have to bring it to the dealer.....

jack the front up and give the front end a shake down...shake the wheel side to side if its loose could be tie rod ends.(make sure your steering wheel is unlocked)

bad shoes in the rear?

ya i did that. no play i replaced my tie rod ends and sway bar links within the last year as well

hows the front wheel bearings/hubs?

honestly didn't inspect them to well but nothing was obviously worn. i will double check that tomorrow

same as checkin tie rods...just up and down,iv worked on cars and i always did a quick shakedown on the car id work on and some i found did clunk or had that loose feeling in it...id let customers know whats up but they said no grinding or anything of that nature.

but hey if its none of the above like said above by keaton could be the rear,like a drum unbalanced and tuggin causing the front to jerk a bit under hard braking cause most brake pressure is put to the front anyhow.
