I put new rotors and pads on my ranger two days ago. Now everytime I brake hard the truck shakes. What is goin' on?

 

is your steering wheel shaking? or the whole front? if you feel it shaking on turns then it's air in your power steering. if you feel it while braking in a straight line, you might want to recheck your installation

 

I haven't noticed it when I am turning, but I usually only brake hard in a straight line. It seems to be the whole front end, but of course I feel it mostly in the steering wheel. Any ideas on what I could have missed during the install?

 

warped rotor possibly, or you messed up something on the installation...

 

Any idea what I could have messed up?

 

could it be rear drums??? or the driveshaft? Mine shakes in rear when braking on hills its the U-Joint I think(on mine)

 

did you get any greese on the rotors while installing them? Or did you wipe them completely off after you were done?

 

it could be that you didn't use brake cleaner before installing the rotors, or you over tightened the bolts on your wheels too much thus warping your rotors.
