Bad Vibrations (Brake Rotor Replacement)

If you’ve ever stepped on your brake pedal and felt your vehicle vibrate, that’s a signal that you shouldn’t ignore.  A pulsating brake pedal is a sign that something is wrong.  Braking action should be smooth, sure, and quiet, not shaky and noisy.

Most newer vehicles have disc brakes, called that because they have a round, flat disc connected to each wheel.  Those discs are the rotors. Other parts called brake pads are squeezed against those discs when you press on the brake pedal.

Remember that vibration we mentioned? That can be caused by the rotor not having a straight, true surface. Rotors can heat up from friction and warp.  They can become thinner from constant wear.  Rotors can rust from the elements they’re exposed to, such as rain, snow ice, and salt.  They can get grooves in them from so many contacts with the pads. 

The signs of worn rotors are vibrations, grooves on the rotor (which you can see sometimes through open spots in the wheel) noise such as squealing or scraping when you brake, and increased stopping distance.   

While it used to be common for rotors to be machined (shaved down to restore their flat surface), newer vehicles have thinner rotors, so your service adviser may suggest you replace rotors when they start showing signs of significant wear.

Brakes are important safety equipment for every vehicle.  They enhance your control while driving, so it’s important that they be regularly inspected and maintained.  A good time is when you have your tires rotated. A technician can then look at all components of your brakes and recommend any service you may need to keep your brakes in top shape.

Read a Good Tire Lately? (Tire Wear)

There's lots of good information to read in books and online.  You might not know that you can also "read" your tires and learn a lot about what shape they're in and if they are in need of attention. It's important to know how your tires are doing because a tire failure can be very dangerous to you, your passengers and others on the road near you.

You read your tire by looking at the surface that rides on the road, where the tread is.  Check out the outer and inner edges.  If you notice there's more wear on the inner or outer edge than on the rest of the tread, your vehicle could be out of alignment.  Wear on an inner or outer edge could mean your wheels are leaning too much to one side.  When you see this, visit our service center soon to have the alignment checked.

What about if both edges are worn? That could be a sign that you don't have enough air in that tire.  In an underinflated tire, the middle is not contacting the road surface as much as the edges, so the edges wear down first.  It could also mean that you're taking corners too aggressively or your tires haven't been rotated on a regular schedule.

Another thing you might see on your tires' tread area is wear in the center of the tire.  That means you likely have too much air in that tire.  Too much air makes your tire contact the road in the middle more than on the edges so the middle wears down prematurely. 

You might also see some smooth spots on the tread in irregular spots. This is called cupping. This is sometimes caused by suspension problems. A technician can examine your suspension to see if it is up to the manufacturer's specifications.

Finally, you may spot tires that are worn unevenly in a pattern that goes diagonal to the tread pattern.  This could mean your tires are out of balance, something our service center can check. They might also check alignment at the same time.

Your tires are the only part of your vehicle that contacts the road surface.  That means your acceleration, traction, steering and braking are all dependent on your tires being healthy. Maintain your tires by having one of our trained technicians read the clues and making sure they're always in roadworthy shape.

Service to Improve Fuel Economy

The price of gas in TN has got people in Memphis talking. It seems that Memphis folks who need a bigger vehicle to carry family and gear, or provide four wheel drive, are hit especially hard. That is why we thought it would be good to review some things that anyone can do to improve fuel economy.

First let's start with how we drive around TN. People in Memphis may not realize that they can really save on gas by just changing a few driving habits. One of the biggest is jackrabbit starts - you know, flooring the gas as soon as the light turns green. That really wastes a lot of fuel. Building up your speed at a slower pace uses less fuel and is easier on your engine and drive train. And don't drive with one foot on the brake. That's also a drag on fuel economy, and it wears out your brakes faster, too.

Another thing Memphis drivers can do is drive more slowly - but only when it's safe. Sometimes on the freeway we drive an extra five ... ten . . . twenty ... over the speed limit. We do it to save time, but it only saves a few minutes out of maybe an hour long drive, and we may use 10 to 15 % more gas. Just leave a little bit earlier, save some money and arrive more relaxed.

Memphis drivers can also try and combine all of their errands for the day into just one trip, rather than several. If you can put off a trip today that can be combined with one tomorrow, you can save some time and money.

Using your cruise control can save money too. Driving in TN at a constant speed really improves fuel economy. Be sure to only use your cruise control under safe conditions; you can look in your owner's manual for some good tips on using your cruise control.

Did you know that reducing the weight in your vehicle saves gas? Clean out the trunk or back seat from time to time so that you are not paying to carry a lot of stuff around Memphis that you do not need in the vehicle. If you live in TN where there is snow and ice, clear it off your vehicle; it adds weight and messes with aerodynamics too.

Another tip is to avoid long idle times, which includes warming it up when you start. Modern engines do not require a long warm up to get going;  just take it easy for a few minutes.

Be sure to get a new gas cap if yours leaks or is worn.

Now, let's start talking mechanical. Bottom line - the better you maintain your vehicle, the less fuel you will use. It all adds up in a big way. For example, replacing your dirty engine air filter will pay for itself in improved fuel economy before your next oil change - and will keep saving you after that.

A clean, well-maintained fuel system really pays big dividends. A clogged fuel filter wastes gas. So does a dirty fuel system, grimy fuel injectors and plugged up PCV valves. A fuel system service decreases the gas you use, and increases the power, so drivers in Memphis can't go wrong with that.

Some of us ignore our Check Engine light. But fixing the problem that caused the light to come on will usually save some fuel as well. It may be a bad oxygen sensor that can really rob your fuel economy.

And, it may be time for a tune-up. Tune-ups should improve your fuel economy. Don't overlook the routine maintenance items, like scheduled oil changes, transmission and cooling system service. Dirty or low fluids actually use more fuel. Just look at your vehicle manufacturer’s recommended service intervals in the owner's manual, or ask your Madison Automotive service advisor for the schedule.

Don't forget your tires. Underinflated tires waste gas. And if your wheels are out of alignment, you won't get the fuel economy you need.

None of these things are very complicated or expensive for people in Memphis to stay on top of. When you maintain your car properly, you save gas today and prevent repairs tomorrow.

A Turn for the Worse (Using Turn Signals)

Distracted driving is bad, you know that.  Daydreaming, talking on the cell phone, putting your makeup on in the rear view mirror.  All bad.  But there's something else that causes more than twice as many accidents, according to a recent study.  And that's people who don't use their turn signals. 

Maybe you're one of them.  One survey said nearly a quarter of drivers were just too lazy to use their turn signals.  Others said they didn't use them because they weren't really necessary.  Traffic laws may dictate otherwise, but statistics show police don't write that many tickets for turn signal violations. 

You may have encountered the driver who cuts into your lane without signaling a change.  Often, that person does it deliberately to catch you off guard so you won't invade his or her space.  And when it comes to young drivers using turn signals, one insurance company survey showed more than two-thirds of those they talked to admitted it wasn't their regular practice.

Knowing that, you may wonder why you should use your turn signal.  The reason is simple.  It lets other drivers know what you plan to do.  Driving it tricky enough with all the moving parts on the road.  The more you know what other people are doing, the more you can prepare for that with the way you drive.

How many times have you seen someone turn left without putting their turn signal on?  That's a leading cause of rear-end accidents. Not only does using your turn signal promote safety, it also shows courtesy to other drivers.

There are some drivers who don't use turn signals because their turn signals don't work.  What a lousy excuse! All of the safety equipment in your vehicle should be working; if it isn't, head over to your repair facility.  Often it's as simple as a burned out bulb or a broken wire. 

Finally, the number one reported reason for not using a turn signal is that drivers just forget to do it.  (And the ones who DO use their turn signals and forget they're on?  We won't even go there.)

Engineers put turn signals on vehicles for a reason.  They help drivers communicate with other drivers.  Using them could save accidents… and lives.
