If you recently purchased a new set of brake pads, you'll want to make sure you observe the bed-in procedures specifically outlined by each manufacturer (click for details). But before you get to that point, you'll need to make sure those brake pads are installed correctly. We can recommend an installer, or you can do it yourself if you're experienced—either way, make sure the pads are installed on new or resurfaced rotors that are clean and without excessive run-out. In fact, if the run-out is more than .004" then you'll want to replace it.
Once installed, you'll want to observe those manufacturer bed-in guidelines very carefully. That means there will be a specific amount of mileage where you'll need to drive somewhat moderately so that the brake pad compounds can successfully develop the necessary film on the rotors. Failing to observe those mileages can lead to excessive heat buildup, which can negatively affect your new braking system.
