Your vehicle's brakes wear out.  It's inevitable. You'll notice it when you step on the brake pedal and feel it harder to stop, or there's vibration when you are braking.  Most modern vehicles have disc brakes that each use a brake pad that press on a disc (disc brakes!) called a rotor.  The friction between them enables you to stop, and each time you do a little bit of the pad and the rotor wears down. The original brakes on vehicles used a rotor that was thick enough to last through at least two replacements of the pads.  But vehicle manufacturers who want to save costs and weight now make them thinner, and sometimes the rotors have to be replaced after the first pad replacement.  But not always. Vehicle manufacturers specify a minimum thickness to provide safe braking.  Sometimes rather than having to have your rotors replaced, they can be put on a lathe and resurfaced.  In other words, the surfaces of the disc can be slightly shaved off so the sur ... read more

If you’ve ever stepped on your brake pedal and felt your vehicle vibrate, that’s a signal that you shouldn’t ignore.  A pulsating brake pedal is a sign that something is wrong.  Braking action should be smooth, sure, and quiet, not shaky and noisy. Most newer vehicles have disc brakes, called that because they have a round, flat disc connected to each wheel.  Those discs are the rotors. Other parts called brake pads are squeezed against those discs when you press on the brake pedal. Remember that vibration we mentioned? That can be caused by the rotor not having a straight, true surface. Rotors can heat up from friction and warp.  They can become thinner from constant wear.  Rotors can rust from the elements they’re exposed to, such as rain, snow ice, and salt.  They can get grooves in them from so many contacts with the pads.  The signs of worn rotors are vibrations, grooves on the rotor (which you can see sometimes through op ... read more

We've all been there.  You park your vehicle on a steeper than usual hill and worry about it rolling down while you're running your errands.  So you decide you'll use the parking brake.  When you get back, you release the parking brake, hit the ignition, put it in gear and—uh, oh—you can feel the parking brake is still on.  It's stuck.  What do you do now? Welcome to the world of infrequently-used parking brakes.  Yes, they do stick for several reasons. It's common for components to corrode and get locked up.  Sometimes if you have applied it extra hard, it can jam.  Could be a rusty cable, could be a spring that doesn't return the brake to its disengaged position.  Some pieces just break when they're stressed for the first time in a while. A caliper or the pivot arm it's on can also stick. There are a few things you can try to unstick it.  Carefully rock your vehicle by putting it first in drive and then reverse.  You ... read more

As the weather changes over from hot to colder, drivers will have to deal with more slippery streets.  And it's important to know how to drive with the brakes you have on your vehicle.  In the 1970s, anti-lock braking systems (ABS) started to be installed on vehicles and they've been a game changer for drivers.  Most modern vehicles have ABS and it's important to know how to drive with them. In older vehicles without ABS, the driver applies the brakes by pushing down the pedal.  That, in turn, sends braking pressure to all four wheels at once.  But all four tires don't have the same traction because the road surface they're each on isn't exactly the same. ABS allows sensors to determine when particular wheels are slowing down more quickly.  The ABS then reduces braking pressure to the wheels that are about to lock up.  That way the wheel turns and the tires keep some grip. (You have to have grip to stop.) It's kind of what drivers try to achieve when ... read more

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, th ... read more

If someone tells you to put the brakes on something, you know it means stop.  And stopping is one of the most important safety maneuvers you can do in any vehicle.  That means your brakes have to work properly.  Let's face it.  You stop dozens of times every time you drive.  And over time, that takes its toll on your brakes.  Friction is what stops your vehicle.  Most newer vehicles have disc brakes, and the parts that wear out the fastest are those that rub against each other every time you stop, the rotors and the pads. The rotors are discs that rotate with the wheels, and the pads are removable surfaces that make contact with the rotors to slow or stop your vehicle.  Bits of both wear off each time you stop, and when enough of either (or both) lose too much material, your brakes become unable to safely slow or stop your vehicle.  The pads usually are the parts that wear out first.  Signs that your brakes might be getting worn are: Y ... read more

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

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

Think of how much abuse your brakes take. Day in and day out, they stop your vehicle when it's going fast and when it's going slow. Maybe your vehicle has been vibrating when you brake, or maybe it seems like your stopping distance is a little bit longer than it used to be. Then it's time to get your brakes checked out. After all, you have to be able to stop if you want to be safe. Nearly all newer vehicles have disc brakes on the front, and many have that type of brake on all four wheels. That makes it likely you'll be getting disc brakes fixed at some time in your vehicle's lifetime. Knowing how disc brakes work is as easy as riding a bicycle. If your bike had hand brakes, you'll probably remember a mechanism that squeezed a couple of pads on each side of your bicycle wheel when you applied the brakes. Disc brakes are similar; but instead of the bike wheel, there's a metal disc instead. If that disc is warped or has irregularities in it, it's going to vibrate. It used to be that roto ... read more

When it comes to preventive maintenance and vehicle care, most San Diego drivers know how important it is to check their brakes. But brakes are more than just brake pads and shoes. There are a lot of components in the brake system, and they all need to be in good working order.The pads and shoes are known as the friction materials in the brake system. They push together, providing friction which stops the vehicle. It's no wonder they have to be checked regularly for wear, and brake pads and shoes need to be replaced periodically.Brake pads/shoes gradually wear out, but that doesn't mean your braking gradually becomes less effective. The pads are engineered so that they maintain good braking until they wear too thin to provide adequate friction. At this point, they need to be replaced.But your braking system also has mechanical parts. These pistons and springs can also gradually wear out or get gummed up by oil, dirt and other road spatter. A brak ... read more
