Taking Your Car or Truck to a Mechanic?
    Before taking your automobile in for service, you may want to check our website for Free questions and answers for your particular
vehicle, learn how some basic systems work, get information on some common problems for
car or truck, or just learn about basic
terminology.
The more information you have, the more intelligent you will be when car repairs are needed. The shop will inspect your vehicle and give
you an estimate before beginning the work. It is a good idea to ask to see the damaged or worn parts before work is done.
    Whenever possible, insist on factory OEM parts. These parts are specifically made for your vehicle. There are many aftermarket
companies that try to duplicate these parts. The old saying "You get what you pay for" is very real when it comes to car and trucks.If you are
not sure of the reason the part must but replaced, ask the technician to show you the specific damage and why it has failed. This is were the
more knowledge you comes in very handy. Also, ask how long the warranty is and if the warranty covers all labor if it were to fail again.
It never hurts to get a second opinion. Ask another mechanic. Once you have received the first estimate, try checking around and make an
informed decision. Cars can get very expensive if not properly diagnosed. A good sign of a quality shop is mechanics with ASE certification.

Front and Rear Brake Operation
The hydraulic brake system consists of the following:
Hydraulic Brake Master Cylinder Fluid Reservoir: Contains supply
of brake fluid for the hydraulic brake system.
Electronic Ignition
The electronic ignition system produces a high energy spark. This
spark is used to ignite the compressed air/fuel mixture at the correct
time. This provides optimal performance, fuel economy, and control of
exhaust emissions. The cylinder that is at TDC of the compression
stroke is called the event cylinder. The cylinder that is at TDC of the
exhaust stroke is called the waste cylinder
The system consists of the following components:
The evaporative emission System (EVAP)
This control system limits the fuel vapors from escaping into the atmosphere.
The EVAP transfers the fuel vapors from the sealed fuel tank to an activated
carbon storage device, the EVAP canister. The EVAP canister stores the
vapors until the engine is able to use the extra fuel vapor. When the engine is
able to use the extra fuel vapor, the intake air flow purges the fuel vapor from
the carbon element and then the normal combustion process consumes the
fuel vapor.
Stability or Stabliltrak System
The vehicle stability enhancement system (VSES) provides added stability
during aggressive maneuvers. Yaw rate is the rate of rotation about the
vehicle's vertical axis. The system is activated when the electronic brake
control module (EBCM) determines that the desired yaw rate does not
match the actual yaw rate as measured by the yaw rate sensor.
