Don’t Skip Out on These! (Vehicle Maintenance Items You Should Never Postpone)

Maybe that little sticker on your windshield is giving you the reminder that it’s time for your vehicle to have an oil change.  You’ve thought, “Aw, I can skip this one and save myself a little money.”  When it comes to things you should never ignore on your vehicle, timely oil changes are number one on the list.  

When the oil stays in your vehicle too long, it can accumulate dirty particles and begin to break down, defeating its lubricating properties.  Skipping or delaying an oil change can lead to far more expensive repairs down the line.

Another is seeing a warning light and doing nothing about it.  Lights that advise you to check your engine or tell you things are running hotter than usual under the hood can be early warning signs to have a technician determine why.  Consider getting the answer earlier rather than later.  It could save you major headaches and money.

Don’t skip having important fluids checked. That includes your engine coolant, brake fluid and power steering fluid.  Big repairs may lie ahead if you ignore them too long.

And don’t put off having other regular maintenance services performed on your vehicle that your vehicle’s manufacturer recommends. Ignoring that recommended interval may void certain warranties, leading you to have to pay for a repair you may not have had to cover yourself.

Regular battery checks are another basic inspection that’s often overlooked.  Batteries can seem like they’re fine until they’re not, and being caught with a dead battery at an inopportune time can cause you unnecessary inconvenience and bills.

Oh, and please don’t skip regular tire inspections, either. A pro should regularly look at the tread, sidewalls and date of manufacture.  A tire failure at high speed can be very dangerous to you and others around you. And if you’re driving with worn tires on slick surfaces, your steering, handling and braking may let you down.

Sure, maintenance costs money and time, but it may save you money in the long run.

It's Brake Time (Brake Calipers)

Race car drivers have demonstrated the advantages of disc brakes, so most modern vehicles use them.  Sometimes just the front wheels have disc brakes, but many vehicles now have them all the way around. 

A major component of the disc brake is called a caliper.  It works by squeezing brake pads against the disc or rotor, kind of like a bicycle hand brake.  The brake pads themselves are what contact the rotor, causing friction to build and the wheel to slow down, but it's the calipers that apply the pressure to the pads.

Caliper design has evolved over the years, and there are two common types.  One is called a floating caliper.  It has one or two pistons on one side of the disc. When you push down the brake pedal, the piston or pistons in your caliper put pressure on that one side.  A mechanism connected on the other side of the disc applies pressure as well, squeezing your disc so the vehicle stops.  Floating calipers are less expensive since they have fewer parts.

The other type is called a fixed caliper.  They use pistons on both sides of the disc, sometimes several.  They are often used in more high-performance or heavy-duty vehicles.

Calipers can have rubber seals to keep out dirt, debris and moisture, but when that rubber wears out, sometimes the calipers can get contaminated.  They can stick or start leaking; they can even rust.  Then your caliper can get stuck applying that "squeeze" when you are not pressing on the brake pedal.  Or they can get stuck in the other position, not applying stopping power when you press the pedal.

When this happens, it's not unusual to feel your vehicle pull to one side when you brake.  You might notice a burning smell from the constant friction if the caliper is stuck on, plus you may feel the heat from the wheel after you park and get out of your vehicle.  Sometimes you'll hear a high-pitched sound or clunk if your calipers are binding up. 

That's your cue to have them checked out at your vehicle service center.  If your calipers aren't working correctly, it can be a safety hazard.  Sticking calipers can affect your ability to steer and stop; this is the kind of "brake time" you need so you can get them back on track and working properly.

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 Strain, No Gain (The Basics of Oil Filters)

Ever wonder what one of the best things is to ever happen to your vehicle's engine?  It's the little thing that usually looks like a can, the oil filter.

Just like your kitchen sink strainer filters out errant particles of food from clogging your drain, the oil filter cleans out small particles that could cause your engine harm.

Your engine operates in a dirty, hot environment and gathers a lot of tiny contaminants like dirt, dust, little metal shards and unlucky bugs that get sucked in.  Get those things circulating in your engine and those little particles can cause friction, which starts wearing out those finely machined metal parts. 

You know how important it is to change your oil regularly.  It's vital that you change your oil filter at the same time to keep the oil as close to brand new as possible.

Most oil filters look like a metal can with some holes in the bottom.  Inside there are carefully chosen materials that can screen out the contaminants while at the same time allow the lubricating oil to pass through.  Early oil filters had steel wool, metal mesh or actual screens.  Then they tried fabric filters using material such as linen and cotton.  Finally, a less expensive disposable filter using paper and cellulose did the trick.

Cellulose or other synthetic media are used in most oil filters today.  Cellulose is inexpensive and effective.  Fibers filter out particulates and let the oil flow.  The other synthetic media have the ability to screen out even tinier particles while not significantly restricting the oil from getting through.  Engineers continue to work on even more advanced filter material.

Choosing the right oil filter is something our pros at McPherson Automotive can help you with  because there are a lot of them out there.  Factoring into that decision are your driving habits, how far you drive and the temperatures to which your engine will be subjected.  While some filters will cost more than others, they may be worth it to extend the life of your engine. 

But most important is remembering to come have your oil changed at McPherson Automotive regularly at the intervals recommended by the vehicle's manufacturer. Just like you wouldn't want to have a plumber come over to fix a clogged kitchen drain, you certainly wouldn't want to have to pay for major engine repairs if they could be prevented by regular oil and filter changes.
