brake pads, like any two surfaces which rub against each other, must ' seat' as it is called and then the pads will have 'adapted' to the irregularities of the vehicle's rotor surface. And,,, it could be that the more expensive rotor needs to be replaced as well - ouch$$$. This seating should take place on average, during the first week of driving. If not, check your bank balance and then humbly go back to the installer.
Pads are much cheaper and should be checked often to prevent rotor damage. It also DOES NOT PAY to have cheap pads installed. We are busy people and don't have time to keep checking things like this, just to save a few bucks on brake pads. 'yeah, I just saved ten bucks on brake pads'
It must be the rear brakes at fault.
They need replaced when they wear out.
Your rotors are warped. You need new brake pads and the rotors turned at a machine shop or replaced.

The most likely problem is warped rotors. Have rotors turned or replaced. Replace front brake pads.

Have the front rotors turned on a lathe at a dealership. check brakes and rotors
You will find that the front brake rotors are located behind the front of your wheel spindle, (behind your wheel and brakes). There you will see the rotors.
