Test results on one inspection of 1,520 tractor and trailer combinations revealed that 46% of these vehicles had brakes that were out of adjustment. The remaining OOS vehicles were cited for such defects as audible air leaks, cracked brake drums, loose brake components, brake linings bowlingballdrillpress not firmly attached to the shoe, brake lining less than one-quarter-inch bowlingballdrillpress thick, brake lining saturated with oil or grease, and damaged or frayed air line hoses or tubing.Interpreting brake termsBefore attempting to specify an air brake system for articulated vehicles, let''s define certain brake terminology so that the vehicle manufacturer, equipment dealer and truck fleet manager are all on the same frequency of communication:Balanced Braking. This would occur on a tractor trailer combination when the brakes'' forces are divided evenly between the tractor and the trailer, or trailers. The trailer brakes would apply just before the tractor brakes and the tractor brakes would release just before the trailer brakes. In other words, every brake in the vehicle combination would be contributing to its designed share of the total braking effort. Also, balanced braking prevents trailer sluing (when the trailer wheels lock and go into an uncontrollable skid), as well as tractor jackknifing.

Before you begin, also call a building inspector to determine necessary posthole depths for your project and to find out if you need a building permit. They''re generally required for fences and decks.Have your layout all set--time is moneyScrupulously lay out your postholes before renting an auger so you can be using the tool the whole time you''re paying for it. Pay close attention to locations and mark the exact centers of the holes with stakes. It''s nearly impossible to move or reposition a hole once you''ve started boring, so it''s important to begin in the right spot. If you need wider holes than the auger will drill or if you need to slightly reposition bowlingballdrillpress a hole, you can easily carve away the sides with hand tools.
