well what is the deal with the brake pulsations? im doing 135 and start braking, 1/4 pressure mind you. and at about 90 i get brake pedal and steering pulsations all the way down to 0. pay my toll, hit it and after about 5 mins the pulsations are gone.

i was already thinking of the zx big brake swap but, now im positive about it. anybody experiance this?

ps pads are 50% frt rear and the rotors have 50 with one cut about 100 miles ago

As tech is alluding to, the rotors are likely warped and need trued or replaced

i'll ask tech tomorrow if hwe did on or off car lathe. the strange thing is if they are warped it should pulsate now but it doesnt. it didnt even pulsate when i pressed the brakes at 135 it started at 90
