Automotive Tips from John's Automotive Care: Brake Noise

Your brake pads are the important parts that rub against the rotor (or disc) to slow and stop your car when driving in San Diego. They eventually wear down.When your pads are worn too much, they won’t stop your vehicle as well. When the friction material is worn away, metal parts of the pad are exposed and you’ll hear a squeal or grinding sound. That’s when San Diego drivers should replace their brake pads at John's Automotive Care. Not only will new pads restore your stopping power, but replacing them on time will prevent damage to the rotor.If your brakes are making noise, ask your John's Automotive Care service advisor to inspect your brakes. Addressing problems early will restore your safety and prevent expensive brake damage.John's Automotive Care6267 Riverdale StSan Diego, CA 92120619-280-9315http://www.johnsautomotivecare.com

Bad Vibes (Disc brake rotor problems)

If you were to name the most important safety feature on your vehicle right now, what would your answer be? A lot of driving experts would agree that it’s your brakes.  Most newer vehicles use a well-engineered and efficient style of brakes called disc brakes.  The name disc brakes comes from one of the components: a disc attached to the wheel hub that is squeezed by parts called calipers.  If you’ve ever ridden a bicycle with hand brakes, you probably have seen how they squeeze against the rim of the bike wheel to stop the bike. It’s similar to the way your vehicle’s calipers squeeze against the disc rotor, with added parts called brake pads attached to the calipers that are what create the friction and stop your vehicle. Here’s why disc brakes need regular maintenance.  Over time, that friction creates wear and tear on the brake pads and the rotors, and you’ll start to see the signs.  Your brakes may have one of the 3 &ldqu ... read more

John's Automotive Care On Your Serpentine Belt

  Today we're going to be talking about serpentine belts for our San Diego, CA, customers. Let's start by talking about the accessories that are driven by the serpentine belt. First is the alternator. That's the device that makes electricity to power the vehicle and recharge the battery. Then there's the air conditioning compressor that makes cool air for you while you're driving around CA in the summer.The power steering and power brake pumps are driven by the serpentine belt in most San Diego residents' vehicles. Those pumps provide pressure that assists your steering and braking.In many vehicles, the water pump is driven by the serpentine belt. The water pump is what circulates the coolant that protects your engine. In some cars around San Diego, CA, the water pump is driven by the timing belt.The radiator cooling fans on some vehicles are also driven by the serpentine belt. Some have separate electric motors. That's really a lot of work for one belt ... read more

John's Automotive Care: Why Replace Your Engine Air Filter?

John's Automotive Care: Why Replace Your Engine Air Filter?

Just as our bodies need clean air to function properly, your vehicle engine needs clean air to operate efficiently. Let's go egghead for a minute. For every gallon of gas we burn driving on San Diego streets, 20 pounds of carbon dioxide comes out the tailpipe. Question: how can a gallon of gas that weighs a little over six pounds produce 20 pounds of carbon dioxide?The answer is that the carbon comes from the gasoline, but the oxygen comes from the air. You see, it takes about 12,000 gallons of air to burn a gallon of gas in your engine. Clearly, your vehicle needs a lot of air to keep going in San Diego. A lot of clean air is best. You've seen the pictures of people in Japan wearing face masks. They want some kind of filter to keep unwanted pollution and germs out of their lungs. Well, your vehicle also works better when its internals are clean. When your vehicle air filter is ... read more

Idle Talk about Engines (Causes of Rough Engine Idling)

When you slow down at stoplight, your vehicle's idle should be smooth as silk.  But what happens when the engine is missing or idling roughly? That's your engine's way of telling you, "Hey, I've got something wrong with me and if you don't get someone to find out what it is, I may not start the next time you turn the key." You can help your service facility if you can describe the problem in detail.  Here's a list of things to make a note of: When is the problem happening, when the engine is cold or when it's been running for a while? Does the rough idling occur when I'm accelerating or when I'm going at a steady speed? Does it happen at high speeds?  Does it happen low speeds? Does it happen at both? Make sure you describe the problem in as much detail because it will help a technician diagnose the problem. One of the first things they'll check is how the spark plugs are firing.  Modern iridium plugs are supposed to last a long, long time.  But they CAN even ... read more
