I have always had a problem with my brakes pulsating due to warped rotors on my '97 FZJ 80. I have had to replace the stock rotors with Toyota OEM two times. Then I finally put on DBA slotted and drilled rotors. They were smooth for a while but now after about 30K, they too are pulsating under braking. It really frustrates me and I feel like the brakes would not work like they are supposed to in an emergency situation. I don't think I can turn these new rotors because of the slots and holes, so I will eventually have to just replace them again. I am not sure what padds were put on the DBA's or if that would even make a difference. What should I do? Has anyone else had this problem.
