My 1994 toyota landcruiser vibrated while braking . before this happen i changed all four rotors and the first drive test after changing new rotors i notice right away when braking it vibrates the entire car, first i thought rotors were warp ,i changed rotors to new rotors two times problem still the same and than i bleed 3-4 time still the same. Please help. Thank you.

 

First welcome, second I would say either another set of warped rotors or you still have air in system.

 

Check the runout in the rotors, then check/change your pads.
