mechanic working on car

Once you know what's in your transmission, and what’s connected to it, it’s much easier to understand how it works. Let's take a look at how it all comes together. At National Brake & Muffler in Griffin, GA, we want to make sure you know how your car works so you can keep it in great condition.

Tires on a fleet vehicle

At National Brake & Muffler in Griffin, GA, we know managing a fleet or commercial truck is no small task. For that reason, we like to keep you informed on things to look out for, and what to do about them. Tires are an area worth paying attention to...tire condition determines ride quality and drivability, and provides useful insight into the condition of your vehicles.

At National Brake & Muffler in Griffin, GA, we know it isn’t always easy deciding what to do next when it comes to major engine repairs. Fortunately, that’s what we’re here for - to help you make the best decision for your situation.

Your vehicle's cooling system is one of the most important systems in your vehicle. Inside your engine, spark plugs ignite the fuel within the cylinders to produce small explosions that propel your vehicle down the road. With small explosions comes scorching temperatures that can destroy your engine if not controlled. There are two types of cooling systems - liquid-cooled and air-cooled. 

Awesome job. Saved me hundreds of dollars to get a second opinion on my brakes. - Marty Y. (5 star review on Google)

Injector

At National Brake & Muffler in Griffin, GA, we see our fair share of damage that could’ve been prevented. Leaking injectors are one of the main ways a diesel engine can meet its demise - but the good news is, engine failure can be avoided, as long as the problem is taken care of.
