Just installed some Napa Rotors and Ceramic pads... After a day and a half of driving I started hearing a popping noise from the front left while braking... If I brake softly I do not hear it... Any idea's?

After turning the front rotors and buffing them, the brakes work great... Never knew you had to turn new rotors out of the box...

Some inexpensive aftermarket rotors have alot of runout. I don`t know the ones you bought but the cheapest aint always the best route. I`ve run accross a couple of nasty ones that were premium rotors too but mostly the over seas garbage has the problems.

your right croozer.

New rotors should never be turned. If they were factory defective though, the problem should have been there from the first test drive. Many factors here that we don't know about.

new rotors that check out to need turning because of excess lateral runout and parallelism are factory defective!
