battery light on the dash

At National Brake & Muffler in Griffin, we know how annoying a dead battery can be. Here’s some information on the subject, that will hopefully help you understand your battery issues a little better.  If your battery dies after your car, truck, or SUV sits for a few hours, the battery itself isn’t necessarily the problem. While having the battery tested is a good place to start, many people mistakenly make a bad battery diagnosis, when actually something in the electrical system is to blame.

diagnostic machine on an engine

Here at National Brake & Muffler in Griffin we often do diagnostics and sometimes the problem is obvious after hooking the car up to the computer and reading the codes.  However, sometimes it isn't obvious during a test drive or after hooking it up to all those computer programs!  You know there is a problem and a Check Engine Light is on with the fleet customer telling you the car has been having issues starting and the light has been going off and on depending on several factors.  No pattern, no simple answer but the problem becomes obvious when you start following the "threads of the issue" thanks to all that ASE Technician training.

At National Brake & Muffler in Griffin, GA, we understand that big trucks mean bigger risk on the road. Here are some tips to remember, to reduce the likelihood of an accident next time you’re on the job.

vehicles in the shop

If you’ve ever been in an emergency braking situation, you’re probably all too aware that the brakes are the most important safety system on your vehicle. And like many other systems in a vehicle, the brakes need regular upkeep to continue functioning properly. One way to preserve the integrity of the braking system is through brake bleeding, and while it may not be as well known as certain services like oil changes, it is a key maintenance item for a vehicle.
