front brake rotors, pads, hardware, have been replaced three times with parts from Advance Auto covered under 2 yr warranty. I'm frustrated with the same issue in fairly short periods of time. I get a pulsating noise in the front brake at 30 mph and above. I can't figure out if it's parts or something else that's causing the problem sliders were removed / replaced and coated with silicon paste and also replaced boots. any thoughts ideas that might help resolve the issue would be appriciated

 

Noise? What does it sound like?

Or is it a pulsing feeling through the pedal?

More details would help. Does the issue appear immediately after installing the new parts? Or does it occur following some event?

Example:
-The brakes are fine after install. The problem resurfaces after I've braked from 80mph on the highway.

Something like that.
