Anybody know what this sound is? Too much brake pad friction? Rotor misaligned or something? It does not respond (noise become louder, go away, etc) with braking inputs.

Hi Ticobrahe,
yesterday I made a first long ride with my brandnew DSR 2016 model. I experienced the same squeaking sound you have.
It seems to come from the rear tire. If I brake with the rear the squeaking is gone, but then It comes back. It is really annoying, especially on slow speed.
I wonder if this is because the brakes are still new or if this a bigger problem.
How do you get this sound fixed? Any ideas from other forum members on this?
Thanks in advance.

Check the frequency of it. If it's in synq with the rear wheel it could be the wheels/brake/rear pulley on belt. If it's the frequency of the belt rotation it's probably the belt.
I have found a mark on my rear pulley where the belt would rub up to it every rotation. It squeeled for a while.

If the squeaking stops when you apply the rear brake lightly, then it is probably the brake pads making the noise. You might try braking hard a few times to bed-in the pads. That might help. Also, sometimes flushing the pads and caliper with soapy water, flushing with clear water, then going for a ride to dry the caliper out can help if the pads are dirty.

My bet would be an over-tightened belt, also brakes that need to be bedded-in as the manual says but also then washed well with a pressure washer or garden spray nozzle should be enough.

Thx for all the helpful replies.
I will have a closer look at the bike at the weekend. Currently i am buried in work.
Hopefully also temperatures will rise a bit at the weekend.

My rear brake did this for the first 2500 miles, then it never did it again (it would squeak when coasting at slow speeds, then stop if I put slight pressure on the brake). 2016 DSR.

Ok, last saturday i drove 110 km on my DSR. Lovely weather. The squealing now almost disappears. I think it was the bedding of the brakes, since the bike is brand new. On my way back i got stuck in a traffic jam. But now that i drive on a motorbike it was really fun to just overtake all of the cars with a smile on my face.
Today i had to wash my DSR. Now she is shiny like new.

Hello I'm Luigi Im new at the Forum
I own a Zero S 2015 and the squealing noise haunted my silent sibling rides for long time since I did change the original pad at the rear brake for compatible SBS pads and the nasty noise just disappeared, I assume that the problem is the same I had when the rear pads were cold then gradually disappear when warmed up but it was very upsetting when finally found this Forum that really give to me a lot of tips and knowledge so I would like to contribute to the community that I feel to be part of it.
