Brake wear is not always obvious from the driver’s seat. Front and rear systems share the work differently depending on speed, load, and the car’s electronics, so knowing which end is wearing first matters. Here is a clear way to distinguish between front and rear wear, understand the most common clues, and know when to schedule service before small problems become bigger ones. How Brakes Share The Work Most cars send more braking force to the front because the weight shifts forward when you slow down. That is why front pads typically wear faster. Rear brakes stabilize the car, keep it straight, and help with parking brake duties. On vehicles with electronic brake distribution, hybrids, or strong stability control, the rear may do more than you expect, so rear pads can wear nearly as fast as fronts. Signs That Point To Front Brake Wear If the steering wheel shudders when you brake from highway speeds, the front end is the first place t ... read more

How a Relative Compression Test Helps Diagnose Engine Problems At Accomplished Auto, we use a test called a relative compression test to help figure out what’s going on when your engine has a misfire or runs rough. This test is fast, safe, and doesn’t require taking anything apart. We hook up a special tool called a lab scope and crank your engine. The tool shows a graph with lines representing each cylinder’s compression (pressure). If one line is lower than the others, that tells us one cylinder might have a problem. We also have other tools for this test as well as some vehicles. Ford for example have tools for this test in OEM capable scan tools as well. This test doesn’t tell us exactly what’s wrong, but it gives us a strong clue. For example, if all cylinders look good, we know the problem isn’t likely caused by low compression. That means we can focus on other possible issues like spark or fuel. But if one cylinder is low, we know to check ... read more

Why Tire Rotation and Balance Matter Tire care isn’t just about keeping your car looking good. It is also about safety, comfort, and cost savings. Here’s why this service matters more than you might think: 1. Longer Tire Life Rotating your tires ensures they wear evenly, which can extend their lifespan by thousands of miles. According to the National Highway Traffic Safety Administration (NHTSA). Performing regular tire rotations helps prevent irregular tread wear. This keeps all four tires performing at their best. Uneven wear shortens tire life; however, tire rotation can save you money by delaying replacements. 2. Better Handling and Safety Even tread wear and proper balance mean better grip and control, especially in slippery fall and winter conditions. Balanced tires also prevent vibration and steering shake. This gives you a safer, smoother ride on highways and backroads alike. 3. Improved Comfort If you’ve noticed your steering wheel vibrating or your ca ... read more

Cold mornings have a way of revealing a car’s true condition. You might turn the key or press the start button and hear a slow, tired crank, or worse, nothing at all. It’s easy to blame the battery, but there’s often more happening beneath the surface. Cold weather drains battery strength and tests your entire charging system. If either one isn’t performing as it should, your car may struggle to start when temperatures drop. Here’s what’s really going on and what you can do to keep your vehicle reliable all winter long. Why Batteries Struggle More in the Cold When temperatures fall, the chemical reactions inside your battery slow down. That means it produces less power for the starter and ignition system. At the same time, cold oil thickens, and the engine takes more effort to turn over. These two factors together make winter th ... read more
