Does anybody here knows how to do brake servicing on the G310R??
My rear caliper has some dirt or something, and its making a noise when breaking, and today I've noticed that it's doing a groove on the disk.
I don't want to go to the dealer for something that small, and I want to learn to do this basic servicing.


(Pardon my English please... I try my best)

... when breaking...

I've meant when braking

... that it's doing a groove ...

I've meant it's carving a groove

anbernardi,
It sounds like this is a bit of work for your dealer.
It is 'nothing small'
It is not normal that your brake makes noise (that you can hear)
Carving a groove is also not 'small' and normal.

It is possible that a little rock is between the brake pad and the disq. Move the bike backwards and see if something falls out.
If not, remove the caliper and clean everything.

If nothing comes out / everything is clean ......................... DEALER !!!!!
Good luck and keep us updated

That's the plan. I want to remove the caliper first, but I didn't find out how (my prior bike had the caliper fixed with a pair of allen bolts, like bicycle hidraulyc brakes, so it was very easy to remove them). As far I can see (with a simple inspection) I have to remove the rear wheel first.
This weekend I have some free time, so I'll spend some time investigating and building a workstand. It's not new to me work with vehicle brakes, but I don't want to ruin it.

Made it!
It wasn't that hard, but not as easy as the videos shown.
I had to use a hammer to put out the peg, because it has some sort of pressure lock.
After that, I took off the brake pads. I've cleaned them and sand them (with a very fine metal sand paper) and put them again.
There weren't some noticeable garbage, but there actually were a groove on the brake pad, so there might had been a garbage that left a mark on the brake pad and in the brake disk.
After putting all back on it's place, I took a test drive and the noise was gone, so, after all, it might have been just a dirty pair of brake pads.

Sorry that I hadn't documented the process, but I have a lot to do today.

Rgds!

Good to hear.
Did you check the rotors for any grooves where the pad makes contact?
Run your finger over both sides of the surface and see if you can feel where
the culprit may have left a mark.
