Don?t Meddle with the Pedal (Brake Caliper Replacement)

If you drive a newer vehicle, chances are it has disc brakes, and one of the components of that type of brake is called a brake caliper.  The caliper allows the pressure from your foot on the brake pedal to eventually move brake pads against discs in your wheels, which then slow and stop your vehicle.  

If you have disc brakes on all 4 wheels, your vehicle will have 4 calipers.  If you have them just on the front wheels, you’ll only have 2 calipers.  Because your wheels and brakes do their work outside and on the road surface, they are exposed to a lot of dirt and debris, as well as enduring heat, cold, moisture and tough treatment in daily driving.  

Your calipers have seals that are susceptible to the heat generated during the repetitive stops in normal driving, which can take a tough toll on those seals. If you drive when your vehicle’s brake pads and rotors are worn, you can ruin your calipers in the process.  

Here are a few signs that a caliper might be failing:  Your vehicle is pulling to one side when you apply the brakes.  Your pedal goes down to the floor when you push on it.  You hear squeaking from the wheels while braking.  You notice brake fluid on the pavement underneath your vehicle after you’ve parked it for a few hours.  

If you are getting any of those warning signs, it’s important to have one of our technicians determine what’s going on.  There are several brake components that contribute to your vehicle’s safe operation, including the calipers, pads, rotors, brake lines and brake fluid.  

Regular brake maintenance is recommended in your vehicle’s owner’s manual to prevent dangerous surprises.  And when you see issues, have your brakes serviced as soon as you see signs of trouble.

Before You Buy a Used Vehicle (Car Inspection before Buying a Used Vehicle)

Before You Buy a Used Vehicle (Car Inspection before Buying a Used Vehicle)

Perhaps this sounds familiar. Your vehicle seems like it’s been around forever, and you’ve decided it’s time to move on.  But when you check the price of new vehicles, the sky-high price tags have you considering a nice, pre-owned one.  

So, you start looking through the ads and find a few prospects.  A couple look great, and the owners say they’re in like-new shape.  But most of us aren’t trained mechanics, nor do we have the equipment to run the tests to determine what’s right and what’s wrong with a used truck, car, SUV or van. 
 
The answer may be to consider having a trained professional perform an independent inspection on the vehicle you have your eye on. Some dealers may conduct their own inspection, but you are best served by having someone not associated with the seller thoroughly check that vehicle you have your eye on.

A technician puts the vehicle up on a lift to look for damage, corrosion or any signs of accidents or flood damage you can’t see when it’s sitting on the ground.  A used vehicle inspection includes checking brakes, wheels and tires, belts and hoses, suspension components and the heating/air conditioning systems.

In addition to inspecting the vehicle visually, the technician can use a professional, full-function scanner to look for codes stored in the vehicle’s memory and diagnose other electrical issues.  It may also show if there have been any warning lights that have come on recently or if someone has wiped the memory to try to hide something.

Unless you are a professional automotive technician, consider investing in a comprehensive, pre-purchase inspection.  No, it can’t guarantee to turn up everything that might fail in the future, but it can be a bargain to have peace of mind that the vehicle you’re considering is worth the considerable investment you are contemplating. It could also give you additional bargaining leverage.

If the Shoe Fits (Brake Shoe Replacement [Rear])

When it comes to brakes on your vehicle, we all know how important it is to keep them working well because they are vital safety equipment.  After all, if you can’t slow down and stop, you can’t drive safely.  

While many vehicles use what are called disc brakes, there’s another type of brakes that are used on the rear wheels of vehicles that have something called drum brakes.  Drum brakes were the original type that were invented in the early twentieth century.  The term drum comes from the part of the brakes that is a housing connected to your wheel.  Inside there are parts called brake shoes that press against the drum when you step on the pedal, and the friction slows and stops your vehicle.  

Signs your brake shoes might need replacing are your rear brakes make noise when you step on the pedal and they vibrate when you brake.  Another sign of bad brake shoes is that your hand brake stops working.  If you notice one or both problems in your vehicle, it’s time to bring it in so a technician can inspect your brake system.  It can be unsafe to drive a vehicle with worn out brake shoes.

There are two brake shoes in each brake, and since they both work each time you stop, when they need replacing, they should be done in pairs. When we replace your brake shoes, we will also inspect other components and parts of your brake system, including your emergency brake cable.  We will also lubricate another part called the backing plate. 

Let us keep your brakes operating as they were designed to. When it comes to safe driving, stopping is as important as going.

Don?t Blow Your Cool (Water Pump Replacement)

It’s always a good idea to keep your cool, and that’s especially true when it comes to some components of your vehicle.  One is the engine.  It’s hot under that hood thanks to the mini explosions that are occurring in the internal combustion engine when it’s running.  Your vehicle has a cooling system which takes the heat out of the engine by moving a liquid coolant to a spot where the heat can escape (the radiator). 

The part that keeps that coolant moving is the water pump, which could probably be more accurately called the coolant pump since water is only one component of the fluid that does the cooling. If the water pump fails, your engine can overheat quickly, and that can cause significant and expensive damage to your vehicle.  Water pumps can be driven by belts (mechanical) or electricity (electric).

Your vehicle’s manufacturer recommends mileage intervals when you should consider replacing your water pump even if seems to be working fine.  That way   you are less likely to have a water pump break down at an inopportune time. Some manufacturers recommend replacing it every 60,000-100,000 miles/100,000-160,000 km.

Sometimes your water pump will fail before that, of course.  One sign something is wrong with the cooling system is if you notice the engine is overheating.  An illuminated engine temperature warning light on your dash or a temperature gauge that shows above normal are two things to look for.

You may also see steam coming out of the engine compartment, which is another sign of overheating.  Both could mean your water pump needs replacing.  We also recommend that when your vehicle’s timing belt needs to be replaced that you have the water pump replaced at the same time since everything will already be apart.

When your vehicle is already in to have the water pump replaced, it’s a good time for a technician to examine other cooling system components at the same time.  Those will include belts, pulleys, hoses, clamps as well as the radiator, thermostat and heater core.

Steer Clear (Power Steering Pump Replacement)

When it comes to ease and precision of steering, today’s vehicles are engineering marvels.  One of the keys to just how good steering is lies in the refinement of power-assisted steering which we know simply as power steering.  At the heart of the system is an electrically or belt-driven power steering pump.  It can apply hundreds of pounds of hydraulic pressure to the steering gear so you can turn your heavy vehicle with little effort.

The more time and distance your vehicle travels, the more wear your power steering pump experiences. One sign your pump may be aging is that you hear a whining or groaning sound coming from your wheels when you turn. You also may feel a vibration through the steering wheel, or the wheel is harder to turn or responding more slowly than normal.  Another sign of trouble with the power steering pump is power steering fluid (reddish-brown) leaks on the ground around your vehicle.

If you encounter these symptoms, have us check your vehicle sooner rather than waiting.  If your steering fails, you may find the wheel may lock up or it may become extremely hard to steer.  Both scenarios can be dangerous.  A technician will check out your vehicle and recommend the necessary repairs.  

They’ll also evaluate the belts, hoses and fluids that are part of your power steering system.  A well-maintained power steering system can ensure that feeling of confidence and precision that makes driving safe, easy and a pleasure.

Cabin Air Filter and Engine Air Filter: What?s the Difference?

You may have heard someone say they just got the air filter replaced in their vehicle.  But did you know your vehicle has two different major air filters and they both perform quite different—but very important—duties?

Today’s vehicles have a cabin air filter, and an engine air filter.  The engine air filter cleans the air that enters your engine so it can run better, and so contaminants don’t foul vital parts.  While the cabin air filter keeps the air inside the vehicle’s cabin clean, the place where you and your passengers sit.  

It is important that you have each of these types of filters changed at regular intervals, or earlier if either shows signs that they’re contaminated. Your vehicle’s owner’s manual often will recommend how long that interval should be.

First, let’s look at the engine air filter. Your vehicle’s manufacturer will offer guidelines on how often you should change the engine air filter as a matter of routine, by mileage or time interval.  

If you see signs of engine air contamination, such as misfiring, an illuminated check engine light, smoke coming out of your tailpipe, or loss of power, you may need to have the engine air filter replaced sooner.  

Next, the cabin air filter.  Again, the vehicle manufacturer will suggest how often you should replace it. But if you notice excess dust in the cabin, on the dash, console or seats, a bad smell in the cabin, or lower air flow out the heating and cooling ducts, you should have us check to see if your cabin air filter needs replacing. In either case, we’ll make sure we replace your air filters - either engine or cabin - with ones that are right for your vehicle.
