Stopping "Brake" Downs (Brake Pad Replacement)

If someone tells you to put the brakes on something, you know it means stop.  And stopping is one of the most important safety maneuvers you can do in any vehicle.  That means your brakes have to work properly. 

Let's face it.  You stop dozens of times every time you drive.  And over time, that takes its toll on your brakes.  Friction is what stops your vehicle.  Most newer vehicles have disc brakes, and the parts that wear out the fastest are those that rub against each other every time you stop, the rotors and the pads.

The rotors are discs that rotate with the wheels, and the pads are removable surfaces that make contact with the rotors to slow or stop your vehicle.  Bits of both wear off each time you stop, and when enough of either (or both) lose too much material, your brakes become unable to safely slow or stop your vehicle. 

The pads usually are the parts that wear out first.  Signs that your brakes might be getting worn are:

• You hear grinding, squeaking, or clicking when you apply them
• It takes a longer distance to stop
• Your pedal vibrates when you brake
• The front of your vehicle pulls to one side when you brake

If you notice any of these, bring your car to us so we can have a technician inspect your brakes. Most brake pads have a wear indicator that indicates it's time they should be replaced.  The technician who is checking things out will also look at your rotors for wear, as well as other brake system components.

With regular inspections and maintenance, you'll be sure that when you need to stop, your vehicle will be up to the task.

A Hot Mess (AC System-Compresser)

Air conditioning used to be a real luxury in a vehicle, but now it's standard in most.  Your vehicle's air conditioning system is built to last a pretty long time, but like anything mechanical, sometimes it fails. 

It helps to know a little about how the A/C works. There's a compressor that pressurizes the refrigerant (you probably recognize the term Freon).  That makes it hotter, so it then goes through a condenser that cools it off.  Then another component takes out impurities and humidity before the Freon goes to a device that makes it lose pressure before it goes to the evaporator.  That's where it gets colder and takes the humidity out of the air. Then your vehicle's ventilation system blows air over the evaporator, cooling the cabin air that gives you such relief on a hot day.

Of all these parts, one that does a lot of work is the compressor.  It has to compress that refrigerant and circulate it through the system.  It turns on and off several times when it's working. The good news is that if it's going to fail, it sometimes lets you know. 

One of the signs that your air conditioning compressor is going bad is a noise under the hood when the engine is on, sometimes a squealing or grinding sound. It usually is pretty noticeable. Compressors have a bearing that can seize up after time, causing the belt that drives it to squeal when it's trying to turn something that won't turn.  It will sometimes cause that belt to break. 

Your service advisor can tell you if your compressor is repairable or must be replaced.  In the case of a broken belt (often a serpentine belt that drives several components) the belt will have to be replaced as well.

The compressor also has a clutch that turns the compressor on and off so it doesn't have to run all the time. Sometimes that clutch can fail, too, and your service advisor will often recommend you replace the compressor and the clutch at the same time. Our technicians can help make sure your air conditioning system keeps its cool, and you along with it.

Heat and your Tires (Tire Pressure Monitoring System)

With hotter weather and brutal heat waves becoming more common, the pressure in your vehicle's tires goes up.  After all, heat causes air to expand, and the air in your tires follows the laws of physics. Overinflated tires can reduce your vehicle's traction, cause a hard, punishing ride and make your tires wear out faster; all are important safety issues.

Four out of every ten drivers rarely check tire pressure. Some rely on their vehicle's tire pressure monitoring system (TPMS) to keep an eye on proper tire inflation.  But it's not designed to do that.

TPMS is a safety feature that has been required on vehicles made in 2008 or later, using sensors in the wheels that alert you to tire pressure problems.  That warning can be a light on your dash, a digital message or a readout of the pressure in each individual wheel.  But a study showed that more than 40 percent of drivers don't even know what the tire pressure monitoring light symbol looks like!

One looks like a horseshoe with an exclamation point in the middle.  The other looks like an overhead view of your vehicle with the tires at all four corners.  They may even show the inflation number (usually in pounds per square inch, or PSI).

The TPMS is designed to alert you that your tires aren't inflated within certain parameters, but the system shouldn't be a substitute for frequently having your tires checked with a tire gauge.  A TPMS light is only required to come on when a tire is 25 percent under the recommended tire pressure; by that time, you're driving on an unsafe tire and causing excessive wear.

Have your vehicle checked regularly by our professionals, and that includes tire pressure checks.  If you do see the tire pressure warning come on, have our service center look at it soon.  You may have a tire with a problem or the TPMS system may not be working right. 

Either way, since your tires are the only contact your vehicle has with the road, your safety depends a great deal on your tires being in top shape and correctly inflated.  Keep your tires properly inflated and your TPMS working to alert you of any problems. And that's not just a lot of hot air.

The Little Valve that Could (PCV Valve Replacement)

It's easy to get letters like PVC and PCV mixed up.  PVC is a plastic that's used in a lot of things, especially plumbing pipes.  And PCV is a valve that helps your engine burn off excess fumes rather than having them pollute our atmosphere. 

PCV stands for positive crankcase ventilation.  When your engine ignites gasoline in the cylinders, some of the gases produced make their way into the crankcase, where oil is held to lubricate the engine.  In earlier days, those gases would be vented out through a hose and go directly into the air.  It was a waste of gasoline (since about three-fourths of the gases were unburned fuel) and a nasty source of pollution.

So engineers devised a one-way valve that directed those gases back into the engine's air intake system to be burned again.  After a while, the PCV valve can get clogged up with gummy oil.  Not only does that reduce the recirculation of the gases, but it can also cause pressure in the crankcase to increase and possibly lead to an oil leak.

Signs your PCV valve has failed are oil leaks around the engine compartment or under your vehicle and poor engine performance. Your fuel economy will get worse. If you notice those signs, we can check your PCV valve. 

At the same time a technician inspects the PCV valve, they'll also check the vacuum hose that runs back to the air intake.  Plus, they'll make sure the vehicle doesn't have any other engine problems that might be contributing to your issues. 

Many technicians recommend replacing your PCV valve with each major tune-up, so you get ahead of any problems before they develop.  Now that you're an expert on PCV, it may be time to check out those PVC pipes in your bathroom!
