Squeaky Brakes on Brand-New Bike

Hiya guys!
About two weeks ago I took delivery of my brand new 2016 Speed Triple R and unfortunately at the end of my second ride my rear brake started producing a low-pitch squeak under hard braking. I have since noticed that it only makes the noise when reaching a full stop and only when the brakes are already a bit warm (after 30min or so of twisties).
When I took the bike to the dealer for its first service I reported the issue. They checked the rear brake and took the bike out for a spin but didn't notice anything unusual. They replied that some bikes develop a "characteristic" squeak and other don't but they hoped that with time it would sort itself out.
After leaving the dealer I had a small hope that somehow something they did would have miraculously fixed the noise. Unfortunately it's still there.
Have any of you guys experienced anything like this? Any suggestions?

Thanks!

 

Thanks guys,
I'm still waiting on a quickshifter to arrive at the dealer which was offered as part of the purchase deal. It should arrive by this week and I will bring this issue up again when I go there to get the quickshifter fitted. I will suggest a thorough cleaning of the brakes.
Anyhow, I'll keep this thread updated.

Ride safe!

 

UPDATE:
Ok, so last Friday morning I took the bike back to the dealer armed with a video I recorded capturing the squeaking noise from the rear brake. As I was about to leave my house I noticed that the brake light was on. I pulled the rear brake pedal slightly upwards and it stopped. Then I pressed it again to see if it got stuck down again and it did. When I arrived at the dealer I immediately told them about this.

Today I got the bike back. It turns out that the squeaking sound was due to glazed brake pads. It could have been due to the dragging brake and/or some moisture getting caught between the rotor and the pads. Their course of action was simply to remove the surface of the pad that was glazed and adjust the rear brake pedal so that it wouldn't drag anymore.

It almost doesn't squeak now. I thought of taking it straight back to the dealer so they would remove a bit more of the pad but decided to give it a few days and see if the noise dies-off. I have since found an article online that states: "glazed brake pads can be addressed by driving a short distance (1/10th or 2/10th of a mile) at normal speeds with your foot lightly on the brake pedal". Instead of this I will just ride normally and wait for that layer of the pads to get worn out.

 

Your post has got me thinking. Next time I ride I will avoid using the rear brake and check if it warms up. They may have fixed the brake pedal so that the light doesn't come on but that doesn't necessarily mean that the brake pads aren't rubbing against the rotor.
