A reel table braking device for use in a video cassette recorder having a deck and a reel table rotatably fixed on the deck through a shaft. The reel table braking device comprises a brake assembly mounted on the shaft of the reel table and movable along the shaft between the reel table and the deck, and a slide plate provided with a first and a second urging means having different height from each other. The brake assembly includes a main brake, a sub brake, and a compressive spring fitted on the periphery of the main brake. The main brake has at least one elastic hook and a bottom plate. The bottom plate protrudes from the periphery of the main brake and supports the spring. Furthermore, the sub brake has at least one hook seat corresponding to the elastic hook, is fitted on the main brake in such a way that the hook is inserted in the hook seat, and is biased upwardly by the spring. The slide plate is movably disposed under the reel table so that the first and the second urging means selectively urge the brake assembly upwardly, thereby allowing the sub and main brakes to come in contact with the reel table, respectively.
