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.

No Fueling Around (Fuel Filter Replacement)

A driver called in to the shop the other day saying his European sports sedan had an odd problem.  He was driving when his car started to slow down.  Applying more throttle didn't help.  He pulled over to the side of the road, shut the engine off and waited a few minutes before starting it up again.  It ran fine… for a couple of minutes.  Then the same thing happened.  He was able to finally get home by stopping and restarting, and he was calling to see if we could take a look at it. 

Turned out it was one of his car's fuel filters that choked up with debris so badly that enough fuel couldn't get through it.  When he stopped the car, enough fuel could flow through the unpressurized fuel line to supply enough fuel for a couple of minutes when he restarted his car. But then the pressure would cause things to clog again.  

There are other symptoms that point to a failing fuel filter. Perhaps your engine misfires, your vehicle is hard to start, or your fuel pump starts making odd noises. 
If you experience any of these signs, bring your vehicle in so we can have a technician check it out. 

Many vehicles have at least two fuel filters. One is a strainer that is part of the fuel pump in the fuel tank, and the other is in the main fuel line. Your vehicle's manufacturer recommends how often yours should be changed, but your driving habits and environment (such as dirty or dusty conditions) may mean yours will have to be replaced more often.  

The technician will also look to see if your vehicle might have another problem that's causing your fuel filter to fail more frequently than normal, such as corrosion in the fuel tank. 

Your engine needs fuel to run. Maintain the health of your fuel system and that will help keep you on the road to your destination.

Timing is Everything (Timing Cover Replacement)

There’s an important part in your vehicle that shields your timing belt, timing chain or cam belt from the debris and gunk that can be kicked up from the road.  It’s called the timing cover.  It’s important because the timing belt or chain is what coordinates parts of your engine called the camshafts and crankshaft.  When they’re in sync, all runs smoothly.  When they’re not, it can cause some serious engine problems.

If your vehicle has a timing belt, without the protection of the timing cover, that belt can come loose from the timing gears or break.  If your vehicle has a timing chain, the cover keeps engine oil circulating around it which lubricates it.  When that starts to leak because of a bad gasket, the chain may not be getting adequate lubrication.  

If your vehicle has a timing cover problem, you may notice engine oil leaking if a gasket is not sealing tightly.  You may hear a strange metallic sound coming from the engine.  Another sign that timing is off is that you notice you’re losing power when you’re going up a hill. 

Usually, the timing cover will not wear out. But if you drive on roads where you’re getting a lot of debris and dirt kicked up into your engine compartment, the timing cover can get damaged and affect your vehicle’s operation.  It eventually could lead to engine problems, so if you notice any of the symptoms mentioned, have one of our technicians inspect your timing cover and gasket.

How Much Does It Cost? (Variations in Vehicle Repair Costs)

Ever wonder why it costs so much more to fix a similar problem in two different vehicles? Let's say you now own an SUV and before that, you owned a car.  Your SUV's air conditioning system needs a new evaporator, but the cost for the new one is way more than you remember it was for your car.  How can there be that big of a difference?

There are many reasons.  For one thing, vehicles aren't all the same.  Yes, they have engines and steering wheels and suspensions, but engineering and design can vary widely among different styles and brands. 

In the case of replacing the evaporator, the one in your former car may have been located in a spot where the technician could get to it easily.  Plus, the part may have been less complicated and, therefore, cheaper.  Your SUV may require the entire dashboard to be removed with special tools to detach the a/c lines from the evaporator.  Plus, since it is supplying cool air to a bigger cabin, it may be more complicated; the part itself may cost quite a bit more.

But you're not an expert, so how do you know the price is fair? This is where it helps to establish a good, long-lasting relationship with a reputable service repair facility.  They know you, they know your vehicle and they value keeping you as a customer. A facility that doesn't care about repeat business may try to suggest more repairs than are needed or inflate their prices.  But those shops are unlikely to stay in business very long since their reputation gets around. 

If you've been taking your vehicles to the same shop for several years, you've had experience with them and know their policy on labor costs and parts prices.  At some point you may wonder if it's worth it to keep putting money into your vehicle, and if you know your service advisor, you have developed a trust for his or her advice. 

Keep this in mind, too.  Vehicle designers and engineers have made significant progress in things like powertrain technology and rust prevention.  That means today's vehicles are meant to last longer.  One study in a major consumer magazine shows that if you can keep your vehicle on the road for 200,000 miles/320,000 km, an average of 15 years, some vehicles can save you up to $30,000 or more. Investing in repairs can make a lot of sense.

Lean Times (Shocks and Springs)

You may have noticed your vehicle going through lean times.  By that, we mean it's literally leaning to one side.  When you notice that, you should get it checked out at your service facility soon because you could have a serious problem.

Many things can cause a vehicle to lean.  You may have problems with your struts, shocks or springs.  They all work in tandem to make your ride more comfortable.  The struts bear the weight of the vehicle's body, the shock absorbers employ a piston that keeps your tires in contact with the road and controls movement of the vehicle's body.  Springs also absorb impacts from uneven road surfaces.

If these components get stuck, either too high or too low, they cause your vehicle to lean.  That's because that side of the vehicle isn't at the height it is designed to be.  A technician will determine where the problem is.  Outside elements such as moisture plus hard knocks to these components can weaken them, eventually resulting in a failure.  The metal can get so fatigued that it breaks.  Often when one side of a vehicle is too high or too low, your service advisor will advise you to have the other side done as well.  That's because if only one side has new parts installed, it won't be level with the side that has old parts. 

There are a couple of other reasons vehicles can lean.  One is that the suspension can be bent or the chassis twisted, again due to wear and tear by driving on rough roads, over badly maintained railroad tracks or in deep potholes. 

Another reason your vehicle may lean is that the tires and/or wheels aren't all the same size.  Or one side might have drastically over or underinflated tires.  This can be a dangerous condition since the imbalance can affect steering and handling.

Considering what drivers put suspension parts, tires and wheels through, it's not surprising that they can be punished so much that they don't hold up like we want them to.  A level-headed driver will make sure to be driving a level vehicle by making sure these components are maintained in good condition.
