I got new brakes and they dont grind. Cant hear a thing! I did not "bed them in" either like I do disc brakes.

I was putting the other one together today and thought his retainer might have come apart. I found one that had a little too wide hole and put it on the bottom.

The springs on this brake are really good. Just dust them off and they are shiny like new, they dont rust or anything. I think its a waste of money unless they are corroded or bent. (I found a cool hook at harbor freight last week that helps not to bend them!)
