Brake Failure
     The one system in today’s cars most drivers take for granted is their  brakes. The good news is that brake failure accidents don’t happen that often,  making up an estimated 5% or less of car accidents each year in the U. S. With  today’s modern systems, it’s unusual for an automobile to suffer a total  braking failure. Even though brake failure is relatively rare in passenger  cars, it’s one of the top causes of  accidents involving trucks and larger vehicles. It remains that the possibility  of brake failure in cars is real as indicated by recent manufacturer recalls.  
       
       Manufacturer  Recalls
The proper functioning of brakes is critical to the safety of motorists and  their passengers. Brake systems are susceptible to failure as any other system  in a vehicle, and as some recent industry recalls indicate, manufacturers’  defects that could result in partial or full failure of an auto’s brakes are  not that rare.   
Nissan has announced a recall involving 10,586 Nissan Sentras because of an  issue that can lead to brake failure, according to a notice by the National Highway Traffic Safety  Administration.  The NHTSA has  determined that in certain 2009 models equipped with Bosch master cylinders, if  the brake fluid becomes too low and the subsequent warning light is ignored, a  brake circuit can fail. If that happens, stopping distances will be increased  and the risk of a crash heightens. To remedy the issue, Nissan dealers will  inspect and replace the master cylinder booster assembly for free. 
In August of 2009, Toyota Motor  Corp announced that it will launch a voluntary  safety recall with the National Highway Traffic Safety  Administration (NHTSA) that will effect roughly 96,000 Toyota and Scion  vehicles sold in the U.S. thanks to possible brake problems. The problem occurs  in extremely cold temperatures in the 2009 and 2010 Toyota Corolla and Corolla  Matrix, along with the 2008 and 2009 Scion xD vehicles, all of which come  equipped with 1.8 liter engines. Toyota will notify vehicle owners from 19  affected states in early September 2009. Toyota dealers will install a newly  designed intake air connector to correct the problem.
BMW in April 2007 recalled over 160,000 SUVs because of a problem that could  cause a potential loss of brake fluid or even the brake circuit to fail completely.
And in May of the same year, Chrysler recalled 60,000 vehicles due to an  issue with potential brake failure. The bonded disc brake linings can separate  from the shoes due to a bonding deficiency, which allows corrosive degradation  of the bonded attachment. Separation of disc linings results in an increase in  stopping distance. This could lead to a safety hazard.
Brake  System Maintenance 
Prevention, it is often said, is better than cure. There may be no sure way  to prevent the possibility of a brake failure accident. Several specific issues  can help contribute to brake failure. Some common problems include the  hydraulic lines not being attached properly and overheating brakes which can  damage brake pads or rotors. And a car may not have a brake shift interlock  system, which is the device that prevents the driver from shifting out of park  without having to depress the brake pedal.
Modern dual circuit brake systems are significantly less likely to fail than  the drum braking system, often found on older cars. And the introduction of  anti-lock brakes has helped to prevent the wheels from locking up if the driver  has to brake hard.
The brakes are one part of the vehicle where it’s fairly noticeable if  there’s a problem. Ususally there are warning signs that there is something  wrong with your brakes. 
     
       - Grinding or squeaking noise when using the brake
 
       - Difficulty actually stopping the car 
 
       - Use of the brakes causing the car to veer to one  side
 
       - The brakes must be pumped to stop  the car or the pedal sinks to the floor
 
     
     These symptoms could indicate damage  to the system's pads, linings, drums or rotors; a leak or excess air in the  lines; low or contaminated brake fluid; or the need for an adjustment. Most experts recommend that you  completely change the brake fluid every year or two despite the fact that this  important point isn’t referenced in many vehicle owners’ manuals. 
       
       Brake fluid that contains glycol starts to attract moisture almost as soon  as it is put in the car’s system and too much moisture can make the brake fluid  unsafe. Brake fluid that has been in the car for a year may contain 2% water.  Brake fluid that hasn’t been replaced in several years may be up to 8% water.  Never use anything other than approved brake fluid for your car.
       
  Brake  Failure Emergency Tips
       With proper care such as annual  brake inspections, maintenance, and repair, brakes should not fail. In the  unlikely event that brake failure occurs, the National Safety Council offers  these tips:
     
       - Try not to panic. Work your vehicle into the right lane       and then toward the shoulder or, if possible, toward an exit. Always       signal and when you reach the right lane turn on your emergency hazard       lights.
 
       - Let the car slow down gradually by taking your foot off       the gas pedal. Simply steer as your vehicle slows and use low gears to let       the engine help slow the car.
 
       - Once off the roadway, shift into neutral and gradually       apply the hand brake until the vehicle stops. If that brake has also       failed, direct the car onto a soft shoulder or rub the wheel against a       curb, which will help you to slow down. 
 
       - Get the car off the roadway and to a safe place to       avoid stopping traffic or being involved in a rear-end collision.
 
       - When safely off the road, put out reflective triangles       beside and behind your vehicle to alert other drivers; keep your emergency       flashers going.
 
       - Raise your hood and tie something white to the radio       antenna or hang it out the window so police officers or tow truck       operators will know you need help. 
 
       - Don't stand behind or next to your vehicle; if       possible, stay away from the vehicle and wait for help to arrive. Do not       be tempted to drive your vehicle, no matter how slowly, without brakes.       Call for help to get your disabled vehicle towed.
 
     
     Brake  Failures Require a Full Investigation 
       Establishing liability for an accident caused by brake failure requires a  sophisticated and expert investigation. Usually accident reconstructionists and  scientific experts are required. The challenge is proving negligence on the  part of the brake manufacturer, auto maker or maintenance shop. Consulting a  personal injury expert who specializes in brake failure law is important to  protecting the rights of an injured party. Typically people injured as the  result of defective brake parts have the right to recover compensation for  their injuries including lost wages, medical costs, disability, pain and  suffering, and more.
