OK I need some help I have an 02 f250 7.3 4x4. when I brake from 50-40 I get a noticable shake....but once I hit 40 the trucks shakes like its gonna fall apart. I checked brakes everything seemed fine rotors were a little dirty but cleaned everything. any other ideas on what it might be?

 

Have the rotors been cut ???

 

yeah did the whole brake job

 

Sounds like it could be a warped rotor.. That is what are Excursion did when it had warped rotors..

 

but it is a brake problem right because it only happens when I brake?

 

Maybe those rotors have been cut too many times & they are too thin & warp

 

so more than likely they did a wrong job at the rotor place?

 

Once your rotors get thin (If that's the case) you have to replace them.

 

if the rotors are warped to begin with you can try and cut them. but sometimes you can't take enought off to get them true. then once there thin they warp very easily. i'd just replace them.

 

Yes that is a brake problem. When the rotors warp. The brake pads do not hit the rotor right. So they vibrate REALLY bad..
