This is the brake tuning kit to make casting easier for Daiwa 21/22 Steez A TW HLC reels. This brake rotor is 0.8mm longer than that of HLC reels, to emit more brake. With this kit, I am able to cast 14g 1/2oz rigs easy, and still cast long with 1oz rigs. Kit includes purple brake rotor and 2 springs. Please replace these of your HLC spools. Chrome soft spring should be set at bottom, and gunmetal stronger spring should sit above silver sleeve. You will surely need bent tweezers, fine pliers and flat head drivers to swap these parts on the spool.
