Warning Signs for Brake Service

Typically brake problems stem from worn brake pads or rotors. When you stop, your brake pads create friction to help slow your vehicle, while your rotors disperse heat to prevent your brakes from overheating. Both pieces are essential when it comes to functioning brakes. Fortunately, if either of these pieces are damaged, we can replace them.
You may also be experiencing brake problems because of low brake fluid. This fluid is responsible for turning the force you add to your braking system by pushing the pedal into amplified pressure that will actually slow or stop your vehicle. It also protects the internal metal components of your brakes from corrosion.

How We Can Help

As your partners in automotive care, we service your brakes as thoroughly as possible, conducting a full inspection before determining and fixing the problem.

FAQs

Q. "Why is the alternator important?"

The alternator helps the battery maintain power. As the car is driving, it’s gaining power from the engine. During this time, the alternator is charging the battery. When the car stops running, the charge from the alternator allows the battery to continue providing power to the car.
Q. "What does the alternator do?"

As an alternate source of power, the alternator helps many features in the car run. It helps your air conditioning maintain proper airflow, powers the radio, and turns on the headlights, among other things. It can also add power to the engine.
Q. "Where is the alternator located?"

You’ll typically find the alternator near the front of the engine, bolted in with two brackets. One is adjustable (to allow for drive belt-tightening) while the other is fixed.
Q. "What are some signs that my starter is going bad?"

Some common symptoms that your starter is going bad or is dead include: clicking or other odd noises, lights working in your car but the engine won't turn, taking more than one attempt to start, or smoke coming from the hood.
Q. "Do you offer a warranty?"

As part of our Nice difference.® commitment to providing our customers the best auto service experience possible, we also offer a3-year/36,000-mile warranty on all the work that we do. We offer this warranty at every Christian Brothers Automotive nationwide, and it will be honored at any location, regardless of which branch did the initial work.
Q. "What is a Digital Vehicle Inspection?"

With a complimentary Digital Vehicle Inspection (DVI) on every visit, you’ll see firsthand photos of your vehicle from under the hood. We’ll let you know if everything is functioning properly or if there are any areas of concern. You can even approve or deny our service recommendations, all straight from your smartphone, or you can, of course, give us a call and we’ll explain our findings in further detail.
