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.

The Third Brake Light (Third Brake Light Service)

So you thought you only had two brake lights.  Look again and you'll see one in the center at a higher level than the two on either side of the vehicle.  They're sometimes in the inside of the vehicle behind the back window, or they could be in the deck lid, on the roof or on the spare wheel carrier,

But why is that third brake on your vehicle? Experts say it helps prevent rear end collisions. Tests done by installing the third brake light in taxis and fleet vehicles showed fewer rear end crashes in the ones that had the extra light. The third brake light was mandated in new passenger cars in 1986 in the US and Canada.  The requirement was added to new light trucks and vans in 1994.

Sometimes it's difficult to know if your third brake light is even working.  Many vehicles have bulb warning systems that alert you to non-functional bulbs, but not all do. Your vehicle service facility will often check to see if all your turn signals, taillights and headlights are working during routine maintenance inspections, and they may notice that the third brake light is out. 

So, do you have to have it replaced? Not necessarily. Many areas only require one brake light to work in the rear of a vehicle. So even though new vehicles have to have the third brake light, you may not get a ticket if it eventually stops working.  But you may be missing an opportunity to drive a safer vehicle if you don't get it fixed.

In 1995, an insurance institute study found that 1986 model cars were involved in 5 percent fewer rear-end collisions from 1986-1991 than they would have expected without the extra light.

Ask your service advisor for advice.  Keep in mind that in these days of drivers distracted by everything from texting to putting on makeup while driving, you can reasonably conclude that anything that makes you more visible to the vehicle behind you adds one more—possibly life saving—safety margin.

Knowledge is Power (Battery Testing)

It’s likely happened to you once or twice.  You head to your vehicle, open the door, turn the key and… lo and behold, your battery is dead. Now you’re stranded, may have to get a jump or a tow, and you’ll definitely be late for wherever you were headed. While your vehicle may sometimes give you warning signs, other times it doesn’t.  

As many as one out of every four vehicles will have to have its battery replaced in the next 12 months.  If you don’t want to be surprised the next time your battery fails, consider having it tested.

There are different types of battery testing.  One measures voltage. Another checks for something called conductance.  By sending a certain type of electric current into the battery, it can measure how healthy your vehicle’s battery is.  There’s also a load test.  It checks how your battery is working while drawing power from it.  Newer test equipment found in professional service facilities can check for a number of different conditions using different methods. 

Most vehicle batteries last around five years.  It all depends on how you drive and in what conditions.  Extreme heat and cold will take their toll on a battery and shorten its life.  Stop-and-go city driving will also place batteries under more stress than smooth, continuous driving.  

So, what are some signs that your battery is starting to show its age? Well, the battery or alternator light may illuminate after you’ve started the vehicle or come on while you are driving.  If you’ve left lights or some equipment on and drained the battery, that can be very hard on it.

Because the battery is one of your vehicle’s most important components, it’s a good idea to have us check it regularly. In addition to examining the battery itself, a technician will also inspect the terminals and cables for corrosion, damage, fraying wires and loose connections.  It’s smart to have us do it before any extreme weather changes are expected or before long trips. In this case, knowledge truly is power.

Gearing Up (Differential Fluid Service)

You may have never thought about it, but when you turn a corner, the wheels on one side of your vehicle turn at a different speed than the other side.  What is this magic? The answer is something called the differential.  

A differential is a gear box placed between the drive wheels and needs lubrication to work.  Over time, that fluid can become contaminated, reducing its effectiveness. You likely won’t be able to detect any signs that it’s happening, though it may get a little noisier over time. 

If you continue to drive with contaminated and degraded differential fluid, the gears may wear prematurely. That can also contribute to excess wear on the drive-wheel tires.   

Two-wheel drive vehicles have one differential while all-wheel and 4-wheel drive vehicles will have two or three.   Your vehicle’s manufacturer has guidelines on how often you should have the differential fluid changed, and we recommend you follow those.  

Changing the differential fluid is different depending on what model and year of vehicle you own.  Some have a drain plug so the fluid can be removed and replaced.  In others, a cover and gasket on the differential will have to be removed and replaced.  

Because differentials have constantly moving parts, they generate heat.  That’s why some have a vent to help dissipate the heat caused by friction, and sometimes that vent will need replacing.

When you bring your vehicle in for differential fluid replacement, our technician will also inspect the differential for other issues and test drive it to make sure it’s operating the way it should.
