Put the Brakes On! (Brake Caliper Replacement)

Keeping your vehicle's brakes in top shape is one of the most important things you can do for your safety and those on the road with you. Most drivers know a little about brake pads and rotors but maybe not so much about another brake component called the calipers.

Disc brakes work by a mechanical system that presses your brake pads against discs called rotors (you can usually see these discs through your wheels). The friction stops your vehicle smoothly when everything is working the way it should.  The calipers use the hydraulic pressure of the brake fluid to apply the stopping power. 

After they've been on your vehicle for a while, the calipers can get stuck or wear out.  If calipers on one side of the vehicle work correctly and not on the other, you might feel a pull in one direction.  You might feel the same kind of pull if the caliper is stuck and is applying constant pressure.  You might hear scraping or squealing coming from a stuck caliper and you might smell burning on that side.  The friction from a caliper that's always applying pressure may cause that wheel to heat up, so after you've pulled your vehicle off the road safely, the wheel with the stuck caliper will might feel hotter than the others

Because there are many different components to the brakes, it's best to leave the diagnosis and repair to a trained technician. They will run each wheel through a series of tests and inspections that can pinpoint the problem.  Sometimes it involves more components than just the caliper that may need changing at the same time.

The best way to make sure your brakes will perform well is to is to have our service center perform regular inspections and follow the vehicle manufacturer's recommended service.  That way your brakes will be ready, willing and able when you call on them to put a stop to things.

The Truth about Tire Pressure (Tire Inflation)

Most light vehicles (under 10,000 pounds/4,500 kg) in North America sold from 2008 model year on have a feature that many people are confused about.  It's the tire pressure monitoring system (TPMS).  You may have some experience with it yourself if you own a newer vehicle.  Vehicles with TPMS have sensors in each tire that are supposed to warn the driver when tire pressure gets dangerously low.  That's important because tires that are significantly under-inflated can cause very serious accidents.

Unfortunately, many drivers think the TPMS does all the work keeping track of tire pressure. To them, as long as the warning light or gauge isn’t giving a warning, the tires must have the proper amount of air pressure in them.  That's not the case.

Tire pressure monitoring systems aren't all created equal.   Some give you a digital readout of the pressures in each individual tire.  But many simply have a warning light that looks like the cross section of a tire with an exclamation point in the middle.  If you don't know what it is, it's because it's not instantly recognizable as a tire.  In fact, one company that makes TPMS, Schrader Performance Sensors, surveyed drivers.  Their study showed that more than 40 percent of drivers didn't know that that warning light was. 

One out of 5 of the drivers who did know what the light was only looked at their tires after the light came on to see if they could see any that needed air; they never checked them with a tire gauge or had someone else do it.  Ten percent of them didn't do anything when the light came on.

In most vehicles with TPMS, the warning comes on only when the tires are more than 25% underinflated.  The American Automobile Association says that's under the pressure you need for safe vehicle operation.

The bottom line is once a month you should make sure your tires are inflated to the manufacturer's recommendations.  That means each tire should be measured with an accurate, external tire gauge.  To be confident you are getting a correct reading, take your vehicle to a reputable service facility where their equipment is calibrated and they know what they're doing.

Severely underinflated tires can contribute to an accident that kills or severely injures people.  The idea behind TPMS is well intended, but the system was never meant to replace regular inflation measurements and maintenance.  Periodically have your tires checked for proper inflation.

Ask Jud's Best Auto Service About the Importance of Service Intervals

Today in our Jud's Best Auto Service blog, we're going to talk about following recommended service intervals. Your vehicle isn't the only aspect of your life with recommended intervals: What about six-month dental cleanings and regular physical exams? Then there's laundry, mowing the lawn, paying your electric bill, changing your furnace filter - you get the idea.

Now, what would happen if you didn't follow these intervals? For one thing, your teeth may get more cavities. You might not discover health issues that benefit from early detection and treatment. And you'd have to wear dirty clothes, be embarrassed by your overgrown lawn and have your power shut off.

We all realize there are some things in life that we have to take care of regularly. If we don't, there are negative consequences. Our quality of life diminishes and it inevitably costs more money.

Have you ever wondered, "How often should I bring my car in for scheduled maintenance?" You can let your friendly and knowledgeable Jud's Best Auto Service technician remind you of the manufacturer's recommendations. He has checklists of what the manufacturer recommends and can find potential problems when he inspects your vehicle. Rely on Jud's Best Auto Service professionals to help you make good car care decisions, that's our job.

For those in Medina who want to be more proactive with their vehicle care, here are some simple ways to remember what has a maintenance interval:

First: fluids. If it's liquid, it's got a replacement schedule. Oil, transmission fluid, coolant, power steering fluid, brake fluid, differential fluid, etc.
Then think tires. They need air, rotation, balancing, and alignment. And while you're thinking tires, think brakes and shocks.
And what makes your car go? Air and fuel. Air filter replacement, fuel filters and fuel system cleaning.

Of course there are more items, but if you remember to take your vehicle into Jud's Best Auto Service for these things, your friendly and knowledgeable service advisor will help you with the rest.

On Board Diagnostics for Your Engine

Starting in 1996, Jud's Best Auto Service service technicians have been able to use a standardized diagnostic system to help determine what is wrong with a vehicle. This diagnostic system works in tandem with the Engine Control Modules for each vehicle's engine. The Engine Control Module is a computer that monitors and controls many engine functions.

Sensors throughout a vehicle send readings to the Engine Control Module. These readings help the computer make adjustments in various vehicle systems to allow for constantly changing driving conditions and even to compensate for minor problems. However, if the computer encounters a situation it can't adjust for, it turns on the Check Engine light. (The Check Engine light is called the “service engine soon” light on some vehicles.)

If the Check Engine light is burning steadily, it indicates a problem that needs to be taken care of soon. If it is flashing, however, the vehicle needs immediate attention at Jud's Best Auto Service. When the Check Engine light is flashing, the vehicle should not be driven at high speeds, haul heavy loads or tow a trailer. Medina drivers need to understand that doing so can cause major damage.

When a vehicle is brought to Jud's Best Auto Service in Medina because the Check Engine light is on, a technician will scan the Engine Control Module to learn why it turned the light on. The answer comes as a “trouble code.” The technician has access to software that allows him to enter the code and find out what it means. The software will also let your Jud's Best Auto Service technician know what might be causing the problem and how to diagnose it.

Notice that the trouble code does not tell your technician at Jud's Best Auto Service exactly what is wrong with the vehicle. It can only let him know where to start looking to find the problem.

Scanning a trouble code and determining what it means is fairly simple for the pros at Jud's Best Auto Service. But the ensuing process of actually diagnosing a vehicle's trouble can take a skilled technician some time. Sometimes this can add up to a significant repair bill. Some vehicle owners mistakenly believe  that the “trouble code” is all they need and think they can then fix their vehicles themselves. Some have tried to save money by purchasing an inexpensive scanner, or they take their vehicles to an auto parts store that offers the scan for little or no cost.

These options are often not the money-savers they seem for Medina vehicle owners. They can end up costing the vehicle owner extra in unnecessary repairs and engine damage.

For example, the trouble code P0133 reads “Bank 1 sensor 1 circuit slow response.” Translated, that means the front oxygen sensor shows a slow response time in changing the mix of air to fuel. The seemingly obvious conclusion is that the sensor needs to be replaced. The vehicle owner purchases a sensor, installs it and happily goes on his way.

However, read the trouble again: a slow response time in changing the mix of air to fuel. Nowhere does this indicate that the sensor is bad. There are a lot of parts involved in changing the air-fuel mix, any of which could be causing a slow reaction time. Those include a bad or contaminated airflow sensor, an exhaust leak, a problem in the electrical system or a leak in the intake manifold. The sensor is merely relaying that the response time is slow; it doesn't indicate where the trouble is.

So the vehicle ends up with an oxygen sensor it did not need, and the delay in repairing the actual problem may have led to further damage to the engine. Both are added costs for the vehicle owner.

Cheap scanners also don't have the ability to read the history stored in an engine's computer. This operating history contains clues that can help in diagnosing engine trouble since it can indicate a developing problem. Jud's Best Auto Service invests a lot of money in high-end diagnostic equipment so that we have access not just to service codes but also to the operating history of the engine.

On-board diagnostics, then, are a tool to help diagnose what is wrong with a vehicle. They cannot specify what part needs to be fixed or replaced, and they cannot replace a well-trained and well-equipped service technician.

Unless you are a trained mechanic, it's good auto advice to use Jud's Best Auto Service for your car care. In the long run, it can save you time, unnecessary expense and frustration. Jud's Best Auto Service can also help you keep up with your scheduled preventive maintenance, which can also save you on repair bills by alerting you to potential problems before they get expensive.
