It's Brake Time (Brake Calipers)

Race car drivers have demonstrated the advantages of disc brakes, so most modern vehicles use them.  Sometimes just the front wheels have disc brakes, but many vehicles now have them all the way around. 

A major component of the disc brake is called a caliper.  It works by squeezing brake pads against the disc or rotor, kind of like a bicycle hand brake.  The brake pads themselves are what contact the rotor, causing friction to build and the wheel to slow down, but it's the calipers that apply the pressure to the pads.

Caliper design has evolved over the years, and there are two common types.  One is called a floating caliper.  It has one or two pistons on one side of the disc. When you push down the brake pedal, the piston or pistons in your caliper put pressure on that one side.  A mechanism connected on the other side of the disc applies pressure as well, squeezing your disc so the vehicle stops.  Floating calipers are less expensive since they have fewer parts.

The other type is called a fixed caliper.  They use pistons on both sides of the disc, sometimes several.  They are often used in more high-performance or heavy-duty vehicles.

Calipers can have rubber seals to keep out dirt, debris and moisture, but when that rubber wears out, sometimes the calipers can get contaminated.  They can stick or start leaking; they can even rust.  Then your caliper can get stuck applying that "squeeze" when you are not pressing on the brake pedal.  Or they can get stuck in the other position, not applying stopping power when you press the pedal.

When this happens, it's not unusual to feel your vehicle pull to one side when you brake.  You might notice a burning smell from the constant friction if the caliper is stuck on, plus you may feel the heat from the wheel after you park and get out of your vehicle.  Sometimes you'll hear a high-pitched sound or clunk if your calipers are binding up. 

That's your cue to have them checked out at your vehicle service center.  If your calipers aren't working correctly, it can be a safety hazard.  Sticking calipers can affect your ability to steer and stop; this is the kind of "brake time" you need so you can get them back on track and working properly.

Used Cars: Kingwood Service Center Advice on What to Do After You Buy

Used vehicles are certainly an economical choice for budget-conscious Kingwood drivers. But how can we know we're getting a good used vehicle and not just inheriting someone else's problems?

There are good used vehicles for sale in the Kingwood area. Vehicles are sold when families upsize, when families downsize or even when someone just wants a new ride. So the used vehicle may be just fine. But some Kingwood used vehicle owners sell them because they don't want to deal with developing or existing problems.

When you're considering buying a used vehicle in Kingwood, ask for service records. Check to see if the recommended schedules for preventive maintenance have been followed. If so, you probably have a great used vehicle on your hands. If there aren't any service records, then assume the worst.

Check the vehicle for obvious signs of problems. Kick the tires if you want to but definitely check them for uneven tread wear. This can indicate alignment problems, worn shocks or suspension issues. Listen to the engine for unusual sounds and pay attention to unexpected odors. Take the vehicle for a test drive and make a list of any concerns you might have.

If the used vehicle you're looking at is a late model vehicle with under 35,000 miles/55,000 km on it, take it to Kingwood Service Center for an inspection. This inspection will reveal many basic or developing problems. Talk to your friendly and knowledgeable pros at Kingwood Service Center about concerns you had on the test drive. Get a heads-up on needed repairs or maintenance.

Previously leased vehicles are often tempting to used vehicle buyers because they are generally newer models with low mileage and have been factory-cleaned. Be cautious, however. Many Kingwood residents who lease vehicles don't bother with preventive maintenance because they know they'll be turning the vehicles in. Again, ask for maintenance records, take the vehicle in for a full-service oil change and consult with the pros at Kingwood Service Center about any problems the vehicle may have.

Older used vehicles are even more problematic for Kingwood used car buyers. Older vehicles simply come with more maintenance and repair issues than new ones. Take these in for a used vehicle inspection at Kingwood Service Center. Usually, a seller will let you do this before you purchase the vehicle. These inspections are very thorough and will help you know what you're getting into. You'll be able to make an informed decision about your purchase. That peace of mind will make the cost of the inspection more than worth your while. It's always good auto advice for Kingwood drivers to purchase a Carfax report on any used vehicle. This report will let you know if the vehicle has been in a major accident and will give you a title history. You'd be surprised what used vehicle buyers have learned from those reports. Know before you buy.

Once you purchase a used vehicle, give it some tender loving care. Give it a thorough cleaning, inside and out — and don't forget the engine compartment. A good wax on the outside will make it look and feel “new.” And, of course, stay on top of preventive maintenance. Used vehicles bought in TX can last a good, long time if they're properly cared for. They're economical to buy and can keep on saving us money if we look after them.

TX: What Is the Risk of High Oil Change Intervals?

TX residents may have heard that vehicles don't need their oil changed as often as they used to. That's true. But it's not the whole story.

Owing to improved engine technology and higher oil quality, most newer vehicles can go longer between oil changes than their older counterparts.

So what is a good time interval for oil changes? How do TX residents know when to change it? And why do we change it in the first place?

Oil lubricates a vehicle's engine, which protects it from friction damage. Over time the oil can collect dirt and contaminants that inhibit its performance. But dirty oil isn't the only problem for TX residents. What you really want to avoid is called oil sludge.

Oil sludge is caused by moisture in the oil and by hot spots in your engine that burn off oil. This sludge is a gooey gel that can clog engine passageways, which can block lubricants from reaching vital engine parts. The result can be engine wear or even engine failure.

Sludge forms rapidly in an engine that is driven under what are termed “severe conditions.” A vehicle's owner's manual includes recommendations for oil change intervals under both normal and severe conditions. Severe conditions include towing a trailer, driving in polluted or dusty conditions, hauling heavy loads or using a car top carrier. Also, extremes in climate such as very hot or very cold temperatures constitute severe conditions for vehicles.

Some people may be tempted to overlook the severe conditions preventive maintenance schedule in their 's owner's manual because of the word “severe.” But consider this: the most common form of severe conditions is stop-and-go driving, rush hour commuting or only driving your vehicle on short trips around the area.

When a vehicle only makes trips under four miles/six kilometers, or under 10 miles/16 kilometers in freezing conditions, the engine doesn't get warm enough for condensation in the oil to evaporate. The result? You get oil sludge build-up. If your driving patterns are the same as any of the conditions that count as severe, you should be changing your oil more frequently under the severe conditions schedule. 

The team at Kingwood Service Center in Kingwood can help you understand what type of oil to use in your vehicle and how it can affect your oil change schedule. Some vehicles are filled with synthetic or synthetic-blend oil at the factory. The owner's manual will recommend that this oil continue to be used in the vehicle, and oil change intervals will be based on this type of oil.

Also, if your vehicle uses conventional oil, but you have some of those severe driving habits we talked about, you can switch to a premium-grade oil to give your vehicle extra protection. The answer to why we change our oil is fairly simple: to protect our engines and make our vehicles last longer and run better. But the answer to how often to change our oil is more complex: it depends on our vehicle, our driving habits, where we live and what kind of oil we use.

When it comes to oil changes, a little information can go a long way to helping people save money and extend the life of their vehicles. Stay safe, and stay on the road.

The Red Menace (How to Deal with Rust)

Rust.  It's worse if you drive in places that use salt on the roads in winter, or if you spend time driving near a body of salt water.  But any vehicle has to deal with rust after years on the road.  And it's not just that rust can eat away your vehicle's body and fenders.  It can be a real problem around your suspension, drivetrain or any place where there's metal.

Rust takes its time.  You don't see it until it's already done its dirty work.  It can wreak havoc with your electrical system.  Sure, vehicle manufacturers do their best to keep it to a minimum, but especially with road treatments like brine around, their task is a difficult one.

The one spot everyone notices is in the paint.  You see a little bubbling under the once-smooth surface.  By the time it bubbles, it's well involved in rotting away that spot of your vehicle.  You wouldn't believe how just a little thing can start the process on its way.  A stone chips the paint down to the metal, moisture and salt reach the steel and rust is off and running.  It could be a scratch in the paint, a little dent, acid from a parking garage, tree sap, you name it.  If you spot it, show it to your service advisor because rust can be more than a cosmetic problem.  It can be a safety issue.

While you can see the rust destroy your vehicle's body, you can't see it destroying your engine.  But it can.  It can eat away at such areas as air intakes or the exhaust system.  Not only can it reduce performance, but also it can disable electrical connections.  In this day and age where just about everything in your vehicle has a computer component to it, just a small electrical problem can strand you at the roadside.

Corrosion can attack your vehicle's chassis or frame, and they are what provide the structural strength and stability for everything attached.  Think powertrain, suspension, axles, window frames. The list goes on and on.  Structural integrity is vital to safety, so the stakes are high. 

Now you can see why rust damages more than just the good looks of your vehicle. There's one thing to remember about corrosion - much of it is only visible from underneath the vehicle.  When you bring your vehicle in to Kingwood Service Center for service, our technician can look for any problems from that important vantage point.  It's always a good idea to point out any spots that you think might spell trouble.  That way you can stay ahead of it and beat rust at its own game.

Move it or Lose It (Dormant Vehicles)

When it comes to your vehicle, driving it too much can cause some issues.  But what about not driving a vehicle enough? That has consequences as well.

Here are a few things that can happen if a vehicle isn't driven enough.  When the engine doesn't operate, the oil isn't lubricating. That means some mechanisms that need periodic lubrication aren't getting it.  And oil that sits around breaks down over time.  In fact, some experts say you should change oil more often if your vehicle sits in the driveway than if you drive it regularly. 

You've heard that expression, "Take it on the highway and blow out the engine.” Well, carbon buildup used to be a problem in older vehicles.  But the real culprit these days is moisture that builds up from combustion if your vehicle never gets hot enough to burn it off. That water vapor can mix with oil and cause sludge to form. There are many vehicle systems (battery, exhaust system, engine seals, etc.) that benefit from driving your vehicle at its optimal operating temperature for a while.

Spark plugs can deteriorate unless they are fired up.  The gas tank can rust from the inside if the metal is exposed from not having fuel in it.  Rodents and insects may see a sitting vehicle as a luxury hotel.  Brakes can rust after sitting around without being used.  Seals and gaskets can dry out.

One wise thing to do is check the operating manual. Some will spell out a maintenance schedule for vehicles that aren't driven regularly. 

One suggestion? Discuss your vehicle's maintenance with your service advisor. Let him or her know how often you drive the vehicle and what you use it for.  Then, you can come up with a maintenance schedule tailored for you, one that might not be covered in the owner's manual. 

If you do have a vehicle that's been sitting around for a long time, it may be wise to have it towed to your service facility rather than trying to drive it with brakes that may not work, spark plugs that may not fire reliably and other systems that may compromise your safety and those of others on the road. 

You may think it's great to have a low-mileage vehicle that you've barely driven, but a complicated, sophisticated machine such as a car, SUV or truck needs regular attention to keep it running safely… and reliably.
