1 Unlike drum brakes, disc brake system are completely, self-adjusting. 2  Brake pedal feel and modulation are improved.  Disc brakes are more common, so you have a wide selection of performance disc brake pads to choose from.
The Big Dipper is located near the north celestial pole (almost the exact location of the North Star) and is circumpolar in most of the northern hemisphere beginning at 41degrees N. latitude (the latitude of New York City), and all latitudes farther north, meaning it does not sink below the horizon at night.
The constellation Ursa Major, also known as the Big Dipper, changes position continuously as seen from Earth. According to EarthSky, the Big Dipper is always visible on clear nights from North America. The apparent motion of the constellation is caused by three factors: the Earth's rotation on its axis, its revolution around the sun and, on a much longer timescale, the relative motions of the stars themselves.
