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.
These are the two bright stars that outline the outer part of the bowl of the Big Dipper. An imaginary line through these stars leads directly to the North Star. Polaris is located at about five times the distance between the Pointer stars. It is the first bright star in that direction. The Big Dipper completes a circle around Polaris every 23 hours and 56 minutes, with the Pointer stars always pointing toward the North Star.
