i recently install aem O.E. big brake for my car front and back. i am using aem brake pad too. the front is ok. but the rear is driving me crazy now. whenever when i drive my on the morning, it got some scraching noise from the rear. but after i drive a while, the noise is gone. is the quality of the rotor or cause the aem brake pad is different than the stock one?

 

did you bleed the lines and bed the pads and rotors correctly?

 

i check everything is fine. the noise only come out when the the rotor and pad are not warm out. after it is hot. it got no noise
