Them's the Brakes (Brake Rotor Resurfacing)

Your vehicle's brakes wear out.  It's inevitable. You'll notice it when you step on the brake pedal and feel it harder to stop, or there's vibration when you are braking. 

Most modern vehicles have disc brakes that each use a brake pad that press on a disc (disc brakes!) called a rotor.  The friction between them enables you to stop, and each time you do a little bit of the pad and the rotor wears down.

The original brakes on vehicles used a rotor that was thick enough to last through at least two replacements of the pads.  But vehicle manufacturers who want to save costs and weight now make them thinner, and sometimes the rotors have to be replaced after the first pad replacement.  But not always.

Vehicle manufacturers specify a minimum thickness to provide safe braking.  Sometimes rather than having to have your rotors replaced, they can be put on a lathe and resurfaced.  In other words, the surfaces of the disc can be slightly shaved off so the surface is flat and doesn't wobble. 

Whenever you bring your vehicle in to have the brakes checked, the technician will measure the thickness of the rotors to see if they can be resurfaced without leaving them too thin for safe braking. If they can, with the right tools and skill, the rotors can be resurfaced.  If not, the rotors should be replaced. 

Discuss the options with your service advisor.  Our service center can recommend replacements that are designed to help stop your vehicle as well as or better than the vehicle's original rotors.

Either way, keep in mind that keeping your brakes in top condition can supply the margin of safety that may one day save your life or the lives of those around you.

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.

I'm Cool With That (AC Exchange)

On a hot day, you want your vehicle's air conditioning to work.  When the air blowing out of your vents isn't cold, it's easy to think, "I'll just take it by the shop and have them top off my refrigerant." But while some people think air conditioning is that simple, it's actually not.

If your refrigerant is low, something has to have happened for it to be depleted.  Perhaps there's a leak in the system.  Or some hoses or clamps have failed.  If the system isn't evaluated by someone who knows air conditioning, it's possible that adding refrigerant will just be a band-aid solution.

It's also possible that contaminants have gotten into the refrigerant, such as carbon dioxide, nitrogen, argon, or air.  Some of those gases do not condense like refrigerant does which can increase the pressure inside the system and strain the lines and other components. At that point, the best course of action may be to have the old refrigerant (with its contaminants) bled from the system and have your AC recharged with new refrigerant.

Bring it to us, and we can inspect and test the system and all its components.  That will include a pressure test for leaks.  Most vehicle manufacturers don't have a service schedule for air conditioning systems, so one way to know when you should have it looked at is when it's not behaving the way it used to.  For example, it may not get cold as fast as it did before or even at all.

So, when hot air is exiting your vents when you want it to be cold, schedule an appointment and have a trained technician take care of it.  Are you cool with that?

More than Pads and Rotors (Brake Caliper Replacement)

You might be familiar with brake pads and rotors, two components of your vehicle's brakes that have to be regularly serviced.  Here's another important component of your brakes: the calipers.

Calipers are used in disc brakes, the type of brakes now found in most recently manufactured vehicles.  A caliper is the part of the brakes that squeezes the brake pads against the discs, or rotors, which turn with your wheels. 

There are different kinds of calipers, but the basic principle is the same.  You press down the pedal, brake fluid activates a piston or pistons that squeeze the brake pads against the disc and the friction slows down your vehicle.

While modern vehicles have a warning system to let you know it's time to get your brakes checked, your brake light usually goes on when your fluid level is low or your fluid pressure is low.  But you may have to look out for signals your calipers are the problem. 

If your vehicle pulls to one side when you brake, that could be a sign that one caliper isn't working right.  If you smell a burning odor coming from a wheel after a trip, there might be too much pressure from a caliper.  Grinding or squealing when you brake is another signal that it may be time to bring in your vehicle so we can check your brakes.

One way to minimize brake issues is regular inspection.  Have them periodically looked at when you bring in your vehicle for an oil change.  The good news is brake issues are more likely to be caused by pads or rotors wearing out.  Calipers last a lot longer, but even they will need replacing every so often.

Rotation Explanation (Tire Rotation Patterns)

You may notice that when you get your vehicle's oil changed, your service adviser may recommend that you have your tires rotated at the same time.  The reasons are simple.  That will allow your tires to wear more evenly and reduce the noise your tires make as you drive down the road.

There are different ways of rotating tires. If your vehicle has non-directional tires and the same size wheels at each corner, here are the different rotation patterns.

For all-wheel drive and rear-wheel drive vehicles, one is called the rearward cross pattern.  The rear tires are moved to the front and stay on the same side of the vehicle, and the front tires are moved to the rear on the side opposite of where they were on the front. 

For all-wheel and four-wheel drive vehicles, use the X pattern.  The rear tires are moved to the front on the opposite side of the vehicle, and the fronts are moved to the rear on the opposite side of where they were on the front.

For front-wheel drive, there's the forward cross.  The front tires are moved to the rear wheels on the same side of the vehicle as they were on the front and the rear tires are moved to the opposite side of the vehicle than they were on the rear. 

If you have directional tires (they only can be mounted in one direction) and the same size directional wheels, the rear tires are moved to the front on the same side of the vehicle where they were, and the front tires are moved to the rear on the same side they were on the front.   And if you have tires with different sizes of non-directional tires and wheels on the front and rear, rotation will be from one side of the vehicle to the other. 

If you have a spare, it's put into the rotation using a forward cross or rearward cross. 

Yep, that's a lot to keep straight.  So, we suggest letting your service advisor recommend the right rotation pattern for you at the interval your vehicle's manufacturer specifies.
