Having to push down on your brakes really hard in order to stop? Brakes squeaking every time you tap on your brakes? It might be time to get some new brake pads and/or rotors.

From the brake pedal to hydraulic brake fluid, brake master cylinder to power brake booster, drum brakes to disc brakes and electronic anti-lock brake sensors, our techs know every part of your brake system inside and out and can perform brake repair on any make and model.


One of the simplest, most effective and inexpensive ways to help protect the life of your car, especially its engine, is to change the oil and the oil filter regularly.

Oil is the lifeblood of your engine. It reduces friction, lessens wear, provides lubrication, forms a seal between the pistons, rings and cylinder walls while helping to cool engine parts.

Diagnostics is important as well. Car overheating can come from a variety of sources.  If your engine is running hotter than normal, either shortly after starting or over time, or if you find coolant puddled beneath your car, it’s probably time to stop by for an inspection.


Our Remanufactured Jasper Motors come with a 3-year unlimited mile warranty. The warranty is nationwide, so no matter where you have a problem – it will be taken care of.
