The brake performance test of FMVSS 105 says the minimum requirements for the brake system on any vehicle driven on the road. The technician must know little about the performance test, not for the sake of being able to quote government regulations, but parts of the test define the kind of performance a brake system must deliver after servicing of the vehicle.
The brake performance test is divided into eighteen stages and begins with a new set of brakes on a test vehicle. The first stage is to install the test instruments on the vehicle and evaluate that they operate correctly. The vehicle then goes through the test called “first effectiveness test.” This test is performed with new brake linings before they have had a chance to burnish in. The vehicle creates 6 stops from 30 mph and six stops from 60 mph. At least one of the stops from 30 mph should be made in 57 feet or less and one stop from 60 mph must be in 216 feet or somewhat less. These stopping distances in other stages of the test are requirements for any vehicle of different size and weight. Remember that FMVSS 105 defines minimum brake performance. It is up to the mechanical engineers to design the vehicle and the brake system to be as per the performance standards.
While the governments sets the rules and regulations for designing and yielding, the technician must understand the ramification if a brake system is not returned to its designed capability. Failure to follow correct repair procedures could cause a vehicle accident, resulting in damage, injuries, and lawsuits. It takes less time to do it right, rather than to take a shortcut that saves time and labor in the short term but may result in much greater loss of time and money later.
Brake Service Laws and Regulations
After new vehicles are sold, the responsibility for maintaining the safe brake operation falls on the vehicle owners. The owners, in turn, completely depends on the service technician to keep the brakes in proper operating condition. Many states and provinces have laws that govern brake system operation and brake service. Some states require periodic vehicle safety inspection, either every year or every 2 years.
These safety inspections usually include at least an inspection of brake components. Some includes dynamic stopping tests, done on a brake system analyzer or on a measured course. If a vehicle fails any part of the safety inspection, its registration cannot be renewed till all defects are fixed. Some states need that a vehicle that has failed a brake test or inspection or that has been cited for unsafe brakes by a police officer can only be repaired at a state-authorized repair facility. Moreover, some states, provinces, counties, or cities have regulations for the licensing or certification of brake service technicians. Some areas have their own certification programs; others depend on Automotive Service Excellence (ASE) certification in brake service. ASE is a non-profit organization which certifies automotive technicians after a series of standard written tests.
Automotive business leaders, technicians, and academics choose and write the test questions. Working in an area that has brake service regulations, the technician will find that safety is not only essential but a good business as well. Service technicians who pass all certification needs for brake systems will get more of the service business, have more secure employment, and earn higher wages. Moreover, any technician who offers high-quality brake service could take satisfaction in knowing that he or she is contributing to drive safety.
