Before you take your first full-ride, the disc brakes on your bike should be bedded in.
Bedding in the brakes will put the brakes through the necessary heating and cooling cycles to sculpt the rotor and pad to each other so they mirror one another. This will increase the contact area of your disc brakes and maximizes the effectiveness of your braking.

You will need to repeat this procedure twice: once for your front brakes and once for the back brakes.
Find an empty strip of road or parking lot; somewhere you can get up to speed and have lots of room.
Get your bike up to a medium speed before slowly braking to a walking speed. Do this without fully locking up the wheel and remain seated while you increase pressure on the brakes.
You do not want to come to a complete stop during this procedure! Reduce speed and come to an incomplete stop before resuming pedaling and getting back up to a medium speed again.
Reduce speed, come to an incomplete stop, resume pedaling.
Repeat the process 20 times. You will notice a gradual increase in stopping power as you repeat the process.
Get your bike up to a faster speed then firmly apply the brakes until you are at a walking speed, remaining seated the full time. You do not want to fully stop or lock up the wheel during this. Reduce speed and come to an incomplete stop before resuming pedaling and getting back up to a faster speed again.
Repeat the process 10 times. You will notice a gradual increase in stopping power as you repeat the process.
Let your brakes sit and cool down for a little bit
Your brakes are now bedded and ready for riding!
