Loud/bad back breaks?

abceire

My back breaks on my back are terrible, they'd break blocks, when I use them they are very loud and don't work very well no matter how hard you pull them. Any ideas? Would it be worth cleaning the wheel surface? I don't think the break blocks are that old. Is there difference in cheap ones from a shop and some of the better break blocks I've seen online?

I see.

Yes, cleaning your blocks and rims is a good idea.

After cleaning the rim/brakes then make sure that they aligned well with the rim.

Close your brakes and see if the pads are fully on the rim. If they're hanging below the rim then you lose braking power and if they're rubbing against the tire then you lose braking power and run the risk of puncturing the tire.

After that you can check toe-ie. The back of the brake pad should be a mm or two further out from the rim than the front of the pad is.
An easy way to do that is to fold over a sheet of paper a few times and put in between the back of the brake block and the rim when closing the pads to align them. That will hold the back out the few mm while you fix things in place.

This toe-in can help with noise.
