This is my first time using this website so here it goes. I believe my mach crush magnetic brakes are not working because no matter if the brake are at 10 or 1 the casting distance is the same and it is still pretty difficult to get a back lash. My spool tension and drag is set properly so I’m not sure what the problem is. 

UPDATE : took apart the reel and put it back together and then for some reason it started to work normally again 

Brakes don’t affect casting distance so much as backlash control during the cast. If you’re not back lashing they’re likely working. 

^ What Mike said - also...drag has no effect on casting distance or backlash possibility...all it does is help you fight the fish once they're hooked.
