Splitting hairs here but... The round knob you tighten or loosen to watch the bait drop is actually the spool tension knob. Has nothing to do with the braking system. The round dial on the opposite side of your reel handle is the magnetic brake. The farther you turn it the more magnets are exposed to engage the spool. And the centrifugal brakes on all reels I have (shimano and Abu) you must remove the palm plate to access. These centrifugal breaks are basically small plastic pieces that the faster they spin, the more they cause resistance. These guys are much stronger than the magnets in my experience. All that to say if you get all of these aspects (some reels don't have all these options) in check you are ready to chunk that plopper, crawler, or 3 arm buzz bait a great distance!
somebody fact check me this is just my opinion!
