I flushed the brake fluid and immediately after that, I am noticing a pulsation (similar to when your rotors are warpped) when I step on the brake 1/2 way at highway speed. I am pretty sure this is not warpped rotors as this problem didn't surface until the fluid change.

Any idea on what I should look for??

 

anyone?

 

Air in the lines?

 

Probably is "warped" rotors* You feel the pulsation more now b/k the OLD fluid was compressible enough to absorb the pulsations and the NEW fluid transmits them to the pedal.

* Rotors don't "WARP" per-se they develop thickness variations due to brake pad deposits and hardness variations caused by improper cool down after hard use.

 

Thanks for the feedback. I loosened the lugnuts a little and the pulsation seems to be less noticeable. I'll drive around a little more to see it's completely gone away.

 

The lug nut worked!!
