My rear brake does not work (disc brake) MTB for anything. It does not skid or even stop for that (brand new) What should I do?
I went to my local bike shop in India and he told me that disc brakes (rear) don't work well because the wire goes all the way to the back of the bike and gets twisted in the process.
I am 13 so I don't know much about disc brakes. How can I make it lock easily? How do I check whether mechanical/hydraulic?
