Hello im new here so try and bear with me.
I have a dual suspension bike with v-brakes, 2 finger adjustable brake levers and is a y frame bike. The problem is that my dad tried to tighten the back brakes a couple of days ago. Cos he couldn't slacken the nut which lets you move the brake pads in and out he had to take off the whole brake. Once he put it back on it is now sitting lop sided sitting to the one side which is making the brake pad rub against my tyre which is hard to pedal.
How can I level the brakes out again? Is it something to do with the brakes spring mechanism?
I'm sorry if this is not clear. If you do not understand i will try and get some pics.
Thank you for any help you give me.
