Hopefully the people here know what I'm talking about because I can't quite find the name of the braking system online (after another quick look it might be the infinity brake system?). But on the opposite side of the handle near the front of the reel there is another adjustment knob, and I find that when casting if I have it set pretty low (2-3) the force of the cast causes the knob to spin and tighten up so I have to re-adjust it after every few casts. Does anyone know how I can fix this?

That knob is very tight on mine regardless of setting.
