Just replaced front pads and rotors with Hawk HPS and Brembos. The brakes worked fine on some 30->0 trial stops, but when I first hit the pedal there's a "thump" and during breaking there's a "thupita thupita thupita" type noise. Does this sound like usual noise from new rotors and pads mating, or is something screwed up?

do u have ABS are u sure its just not that , if not check to c if everything is bolted up tight

Yes I have ABS, but this sound is different from the ABS sound (I know what that sounds like).

Suppose I could take the caliper off and reinstall it and make extra sure it's all tightened down properly.

u do that and tell us how it works out

RE AND CHERYL

The thump is not normal, but when I installed my Powerslot rotors and Hawk pads I had a wierd sound from the brakes for a day or so. Not sure how to describe it but I'm pretty sure it was from the pads hitting the slots.

its prolly not the same thing but i added drilled and slotted rotors on the stock settup and never had this happent to me ,

hope u find ur problrm bro

It turns out the caliper was loose . Tightened it down and it's working perfectly.
