Bad Vibes (Disc brake rotor problems)

If you were to name the most important safety feature on your vehicle right now, what would your answer be? A lot of driving experts would agree that it’s your brakes.  Most newer vehicles use a well-engineered and efficient style of brakes called disc brakes. 

The name disc brakes comes from one of the components: a disc attached to the wheel hub that is squeezed by parts called calipers.  If you’ve ever ridden a bicycle with hand brakes, you probably have seen how they squeeze against the rim of the bike wheel to stop the bike. It’s similar to the way your vehicle’s calipers squeeze against the disc rotor, with added parts called brake pads attached to the calipers that are what create the friction and stop your vehicle.

Here’s why disc brakes need regular maintenance.  Over time, that friction creates wear and tear on the brake pads and the rotors, and you’ll start to see the signs.  Your brakes may have one of the 3 “S” sounds: squeaking, squealing, or scraping. The sound is usually the first sign of brake pad wear which can lead to rotor damage.  Soon you may notice a pulsating or vibration when you brake. That’s because your once smooth and straight rotor disc is warping from the heat generated from friction. Or it may be due to wear.  Eventually, your brakes will take a longer distance to stop your vehicle, and the rotors can have grooves carved into them.

When you start noticing any of these signs, it’s a good idea to have them inspected by a trained technician.  They will measure the rotor thickness, check wear patterns for grooves and heat discoloration, and see how much of the brake pads remain. They will also check to make sure all brake components are moving freely, check your brake fluid, and look for corrosion.

Most vehicle manufacturers require worn or damaged rotors to be replaced, not resurfaced. It’s all part of a complete brake job, replacing pads and the brake hardware parts along with the rotors. It reduces the chance of premature failure.

How often you will need your brakes serviced depends on the manufacturer’s recommendations, your driving habits, and the environment you live in.  Your service facility can recommend the best replacement parts based on those factors. 

Regular maintenance and attention are vital for keeping your brakes performing like they are designed to. Remember, your brakes are your vehicle’s most important safety feature.

Don't Be Fuelish

If you smell gasoline in your vehicle, pay attention to your nose. That's because it has an important message for you.

Newer vehicles should never have a gasoline smell inside. One of the most dangerous conditions can come when your fuel line system has a leak or multiple leaks. Vehicles with fuel injectors are under pressure, meaning a crack or small hole in a fuel line can allow vaporized fuel to escape, sometimes around hot engine parts. Gasoline vapor and hot metal? You see the problem.

One of the most common causes of a gasoline smell inside a vehicle is a fuel tank leak. The gas tank can rot or be punctured by road debris. A Niel's Auto Service technician can evaluate the condition of your fuel tank and suggest either repair or replacement.

Fuel injectors can develop small leaks around their seals or O-rings. Those can deteriorate over time as the material they are made of gets old and less flexible. A technician can replace those parts.

Modern vehicles contain something called a charcoal canister. It gathers evaporating gasoline vapors from inside your fuel tank and prevents them from venting out to the atmosphere. If that canister has a leak, you'll smell it. One hint that you have a problem is the Check Engine light may come on.

You may have a leak in your fuel tank vent hose. Or you may be smelling gasoline simply because your gas cap is loose, the cap is faulty or—yes this does happen—your gas cap is missing altogether.

Consider the dangers of gasoline fumes seriously. Inhaling them can be bad for your health or they may start a fire. Don't fool with fuel; have gasoline odors checked out right away.

Rotation Explanation (Tire Rotation Patterns)

You may notice that when you get your vehicle's oil changed, your service adviser may recommend that you have your tires rotated at the same time.  The reasons are simple.  That will allow your tires to wear more evenly and reduce the noise your tires make as you drive down the road.

There are different ways of rotating tires. If your vehicle has non-directional tires and the same size wheels at each corner, here are the different rotation patterns.

For all-wheel drive and rear-wheel drive vehicles, one is called the rearward cross pattern.  The rear tires are moved to the front and stay on the same side of the vehicle, and the front tires are moved to the rear on the side opposite of where they were on the front. 

For all-wheel and four-wheel drive vehicles, use the X pattern.  The rear tires are moved to the front on the opposite side of the vehicle, and the fronts are moved to the rear on the opposite side of where they were on the front.

For front-wheel drive, there's the forward cross.  The front tires are moved to the rear wheels on the same side of the vehicle as they were on the front and the rear tires are moved to the opposite side of the vehicle than they were on the rear. 

If you have directional tires (they only can be mounted in one direction) and the same size directional wheels, the rear tires are moved to the front on the same side of the vehicle where they were, and the front tires are moved to the rear on the same side they were on the front.   And if you have tires with different sizes of non-directional tires and wheels on the front and rear, rotation will be from one side of the vehicle to the other. 

If you have a spare, it's put into the rotation using a forward cross or rearward cross. 

Yep, that's a lot to keep straight.  So, we suggest letting your service advisor recommend the right rotation pattern for you at the interval your vehicle's manufacturer specifies.
