Automotive Tips from A.G. Automotive & Diagnosis: Brake Noise

Your brake pads are the important parts that rub against the rotor (or disc) to slow and stop your car when driving in Winnetka. They eventually wear down.

When your pads are worn too much, they won’t stop your vehicle as well. When the friction material is worn away, metal parts of the pad are exposed and you’ll hear a squeal or grinding sound.

That’s when Winnetka drivers should replace their brake pads at A.G. Automotive & Diagnosis. Not only will new pads restore your stopping power, but replacing them on time will prevent damage to the rotor.

If your brakes are making noise, ask your A.G. Automotive & Diagnosis service advisor to inspect your brakes. Addressing problems early will restore your safety and prevent expensive brake damage.

To Fix or Not To Fix (Tire Repair)

You know that sinking feeling when you realize one of your tires has a problem.  It may be making an odd noise or behaving oddly when you're driving.  You may hit a pothole or curb and one suddenly goes flat.  Or you may head back to your vehicle and discover it has one tire deflated without a clue of what must have happened to it.

With a lot of different tires hitting the streets these days, the issue of whether to have a tire repaired or replaced can be tricky, and we strongly recommend you have a trained technician help you make that decision. 

One of the most common causes of flat tires is picking up a screw or nail in the tread area.  Many of those can be patched and plugged if the puncture isn't more than ¼ inch/6 mm in diameter. Most tires can handle two of this type of repair, but any more and you should buy a new tire. 

If there's a puncture or bulge in the sidewall or shoulder, the rule of thumb is it's not repairable.  The sidewall doesn't have the reinforcements that the tread area does.  In fact, any puncture that's more than a ½ inch/12 mm away from the edge of the tread should not be fixed. 

Many newer vehicles have no spare tires (to save weight and fuel) and instead have a type of tire called "run-flat."  Sometimes, the only way you know they're deflated is when the tire pressure monitor alerts the driver.  Driving on them more than 50 miles/80km can render them un-repairable.  They may be fixable if you pulled off to the side of the road before driving on them too long. Our technicians can evaluate whether they can be driven further or should be replaced.

Other vehicles with no spare include a can of tire sealant and a compressor.  If you use it, tire experts say to have the tire professionally repaired as soon as possible.

If you have had a flat tire, try not to drive on it unless it's necessary to get your vehicle away from a dangerous situation.  Our technicians can evaluate any tire you may be having problems with and recommend whether repair or replacement is the best option. Your safety is riding on your tires.

Introduction to Diesels for Winnetka, CA

Something you're going to be hearing a lot about around Winnetka, CA, is diesel engines. We're not talking about semi-trucks and buses; we're talking about diesel engine cars, pick-ups and SUVs.

Most people in CA are surprised to learn that around half the cars on the road in Europe have diesel engines. Nearly all import brands offer a range of diesel engines abroad – even the ultra-luxury brands like Mercedes and BMW. For the most part, these diesel engines haven't been available in Winnetka, CA. But that's about to change.

In the past, North American diesel fuel has had a much higher sulfur content than European fuel. Recent environmental laws have required changes in diesel formulation and emissions standards here in Winnetka, CA, so we are now ready to start seeing more diesel options offered over the next few years.

Why are so many Winnetka drivers interested in diesel engines? Well first off, diesel fuel is more energy dense. There's more power in a barrel of diesel fuel than there is in a barrel of gasoline. The result? Better performance and improved fuel economy.

Diesel powered vehicles get about 20 percent better fuel economy. And as for power – why do you think that the majority of new heavy duty pick-up trucks are being sold in Winnetka with diesel engines?

If you think back to the late 1970's and early 1980's, you may shudder when you think of the diesel powered cars of the day – noisy, smoky, under-powered beasts that rattled and shook their passengers. Modern diesels sold in CA have evolved considerably.

They are quiet, clean – and powerful. They're so refined that many Winnetka drivers can't even tell they're riding in a diesel powered vehicle. In addition to fuel savings, diesels generally last longer than gasoline engines because of their heavy duty construction.

Another thing the Winnetka green crowd takes advantage of is the use of bio-diesel in diesel vehicles. Bio-diesel is made from vegetable oil – even recycled cooking oil from Winnetka restaurants. There is a lot of buzz about hybrid cars in CA. Look to diesel-electric hybrids in years to come to make a good idea even better.

Every year, manufacturers introduce new diesel models. Look for diesels in domestic light trucks, SUVs and passenger cars. Import brands have plans to bring more of their outstanding diesel engines to CA as well.

New Winnetka diesel owners need to know that properly maintaining a diesel engine is somewhat different than a gasoline engine. Fluid change intervals are different. Emissions control devices have to work harder to filter diesel fuel and to scrub the exhaust so you will need to pay attention to that. And the fuel injection system operates at much higher pressures than gas fuel injection systems, so it's important to keep your fuel system clean with a diesel.

The good news is that A.G. Automotive & Diagnosis in Winnetka is keeping up with the new diesel technology and will be able to advise you on maintaining your diesel.

When we tell you to look for more diesels on Winnetka streets, you won't be looking for smoky tail pipes as a clue. You also won't be listening for that familiar big rig rattle. And, you certainly won't be waiting for them at the stoplight, because modern diesels are as quick as their gasoline counterparts.

Nighttime Visibility in Winnetka

There are a number of factors that contribute to the high nighttime accident rate in the Winnetka area, things like drowsy driving and a higher rate of impaired driving. Without a doubt, visibility is a major contributor. Let's focus on visibility…

It's said that 90 percent of our driving decisions are based on what we see. Nighttime driving has the effect of reducing 20/20 vision to the equivalent of 20/50 vision. What you could clearly see at 50 feet in daylight can't be seen until you are just 20 feet away at night.

Too make sure your headlights are giving you the greatest visibility, visit us at A.G. Automotive & Diagnosis, located at 19735 Sherman Way Suite 2, Winnetka, CA 91306. Please give us a call to make an appointment: (818) 438-9608.

Accident avoidance is dependent on reaction time. Reaction time deteriorates measurably in low light conditions. One thing we can do to improve visibility is to make sure our headlights are as bright as they can possibly be.

Headlamps dim over time. They dim so gradually that you may not notice it. Many experts suggest replacing your standard or halogen headlamps once a year.

If your vehicle has standard headlamps, consider upgrading to halogen lamps. They make a big difference. And there are upgrades available within the halogen category as well. This once-a-year expense is very modest compared to the safety benefits.

Some vehicles come with high intensity discharge – or HID – headlamps. These lamps should last for the life of your vehicle. They are very bright and are clearly the best option for nighttime driving. Depending on your vehicle, you may be able to upgrade to HID headlamps. Talk with your Winnetka area service advisor at A.G. Automotive & Diagnosis about options for your car.

Another startling fact is that 90 percent of vehicles on the road have dirty or yellowed headlight covers. Dirty is easy to fix. Just run the window washer over the headlight cover when you stop for gas. Get those bugs and dirt off the cover.

Now plastic headlight covers can yellow or become hazy over time. They can be restored to clarity with a special polishing process. Our pros at A.G. Automotive & Diagnosis can help you with this service.

It's also vital to keep your windshield clean and streak free when driving at night. Make sure you have plenty of washer fluid and that your windshield wipers are in good working order.

We recommend replacing wiper blades twice a year – in the spring and fall. Fall is also a good time to replace headlamps so you'll be ready for those long winter nights.
