2002 chevy z71 - I had a pretty bad pulsating in my brake pedal so about 2 months ago I had the rotors turned. It was better but not perfect for a couple weeks. Lately it has gotten really bad. Today I went out and bought new rotors and put them on. (still have 1/4 inch of brake pad) It is better but there is still a slight pulsating feel. Any ideas of that else this could be? I have a feeling, since when I turned them and it was a little better, then got bad again the new rotors will do the same. Oh and just visually, the rotors that I had turned 2 months ago looked fine when taking them off. There was nothing that looked warped but again that was just visually checking. Any ideas?

 

check your hub and axles.

if your hub is warped at all it can cause that problem and i have a buddy with a trailblazer and his axle got bent and that caused his pedal to pulsate which also caused his rotor to wear only in certain places so the pulsating got worse over time

 

I assume when you had the rotors turned the first time, you changed the brake pads?
