The sole function of the brake system is to create friction to stop the car from any speed. Brake problems are usually obvious because they affect the manner in which the car slows and stops. Problems which affect the car's handling or create noise may also be caused by faults in the suspension or steering systems. Information on troubleshooting these systems can be found in SUSPENSION AND STEERING. For more help in selecting the appropriate section, see the discussion of troubleshooting in FUNDAMENTALS at the front of the manual.
