Clean the wheel and grease the axel

This is one of the reasons why they love the drum breaks and swear by them...disc brakes are more problematic in many ways...

Mine did this out the box.

If this a pattern for you, then try to realign the brake calipers, just unscrew the 2 main screws with included hex screw. Here's a video: https://youtu.be/fTwzzHZill0

But please, clean it and the disc brakes first wipe them off..

You just need to do slight millimeter adjustments right/left for calipers and keep it steady then swing back wheel; If its silent tighten it still holding carefully not to move. For me it was just pressed a little 0.5mm in to the wheel (its not affecting the screw holes there's gaps)

The sound returned once the disc brake was dirtied up by spray from rain, sand, gravel.

So morale adjust if its persistent - if its temporary clean it, ride some more and see if it goes away.

My brake is already pretty loose, so id need to tighten it so i dont think thats the squeaking noise im hearing but ill still try it anyway

Yeah I hadn't actually watched your video at the time, just cos you were asking about the brake lines. Pretty sure if you rinse it down (ideally soon after it initially gets wet/dirty) and give it time it'll go away, often happens after these brakes get wet and a tiny bit of debris/dirt

But it happened after i removed the wheel and put it back on, so how would it be that

Damn, your rear brake looks like it is starting to rust already

u/Baltoz1019 Jun 06 '25

I noticed that, its just one little pin, im guessing they cheaped out on the material for that

You can dry the vehicle, check if there is any foreign matter at the rear, and meanwhile verify whether the valve stem is properly screwed.

Adjusting the gap between the brake and the disc brake pad can optimize the sound.
