Problem: Article: The compass rose is a series of 3 circles surrounded by numbers. The outer circle is to help you find true north, represented by a star or 0. The inner circle points to the magnetic north pole at the time of the chart's printing. You can use a magnetic compass to navigate with the compass rose as a guide. Keep in mind that the magnetic field over the Earth changes over time, so you will need a magnetic compass or an updated map to make use of the compass rose. These buoys mark water channels. The colored circles you see on a chart correspond to buoys you will see floating along the channels as you travel. Travel markers are numbered, making tracking your route easy. Red markers show the right side of a channel, while green markers show the left side. The different colors keep you oriented no matter which way you travel. The anchor is a familiar symbol on charts showing waterways close to land. An anchor means you can let down your boat's anchor safely in that area. Anchoring points may be labeled with numbers or descriptions to describe what kind of boats are allowed to stay there. For example, an anchor point marked "DW" means deep water. Only deepwater vessels will anchor there. A number like 24 stands for 24 hours, so you can only keep your boat in the area for a day at a time. Dangerous obstacles like rocks and shipwrecks are all circled. Some circles are dotted, meaning that the obstacles are submerged. If the lines are solid, the obstacles are at least partially above the water. Many modern charts now mark these spots in purple. Obstacles are generally represented by circles with symbols like asterisks and plus signs. There are many different symbols and they often vary between charts. Some charts use picture symbols, such as a boat to represent a partially-sunken shipwreck. Currents are indicated by arrows with numbers over them. The direction of the arrow tells you which way the current moves. The number lets you know the water speed in knots. Currents and tides change all the time. Take the arrows as a prediction for the way water normally flows. Keep watch as you travel for anything out of the ordinary. Since charts have a limited amount of space, mapmakers have to rely on abbreviations to label markers. Some letters indicate the type of seafloor. Others label landmarks like towers, wharves, and government stations. Some common seafloor abbreviations include S for sand, M for mud, and C for coral. Rky stands for a rocky floor. Tr indicates a nearby tower, while Whf stands for wharf and Bn means beacon. CG may indicate a Coast Guard station on a U.S. map. The full title of the chart is NOS Chart No. 1: Symbols, Abbreviations, and Terms. It isn't actually a sea chart, but it contains a list of all the chart symbols you may encounter. Download it from the NOAA's website or purchase a copy from a commercial chart vendor. The chart covers all U.S. charts.

Check with your government's maritime office for a reference.
Summary: Use the compass rose to identify the direction you are traveling. Follow red and green buoys for navigational guides. Look for anchors to find anchoring points for boats. Note rocks and other dangers circled on the map. Follow arrows for the speed and direction of currents and tides. Read abbreviations to identify important features in the area.

Problem: Article: Fasten the emergency brake cable to the replacement brake shoe on the same side your removed it. Pull up the cover again and slide the cable into the proper slot on the shoe (it will look the same as the one you removed it from). . You will need to transfer the return spring (at the top of the shoe) and the small emergency brake spring (near the center of the shoe). If your vehicle has any other hardware on the brake shoe, transfer it to the new one as well. . You want to avoid squeaking and rubbing of the brake shoes. For this reason, you should grease any bare or rubbed spots on the backing plate. . There will be a hook at the end of the spring and a slot in the bottom of the brake shoe. Hook the spring into that slot. Now it is time to put the first brake shoe back into place. Once you get it lined up, hold it there until you can replace the retaining ring. Put the spring that goes with the retaining ring in place over the small rod that protrudes from behind the brake shoe. Place the ring over the spring and press in and twist until the ring slides over the rod and locks into place. Now it is time to begin installing the second brake shoe. Again, you are going to start with the bottom spring. You will need to line it up with the adjusting spring lever. Here you will use the flat end of your brake spring pliers to pry the spring into place and hook it at the top of the second brake shoe. This will connect the two brake shoes. Follow the same procedure as you did with the first retaining ring. Place the spring first, then push and twist the ring into place. This screw changes the position of the adjusting spring, which in turn changes the position of the brake shoes. Since the new shoes are thicker than the old ones, you will need to set the adjusting screw to account for that. Use one screwdriver to push the automatic adjuster assembly down and the other to twist the cog that loosens the adjuster.
Summary: Re-install the emergency brake cable. Remove any parts from the old brake shoes and transfer them to the new brake shoes. Grease the backing plate. Slide the bottom spring onto the new brake shoe. Slide the show into place against the backing plate. Replace the retaining ring for the first shoe. Slide the bottom spring onto the second brake shoe. Put the brake shoe into its proper place against the backing plate. Fasten the adjusting spring onto the second brake shoe. Replace the retaining ring for the second shoe. Use two screwdrivers to set the adjusting screw.
