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 the ... read more

Bet you didn't know: Some of the earliest rearview mirrors were marketed as "Cop Spotters" so drivers would know when police were following them. Who wants a ticket, anyway? According to eBay Motors, Elmer Berger first patented a rearview mirror that was mounted on the front fenders, on the spare tire secured to the side of the car of at the top of the driver's door frame. About 80 percent of your vehicle is recyclable. So says The Balance. That means four-fifths of most vehicles can be recycled. Much of that recycling is done by automotive aftermarket recyclers. Between the U.S and Canada, they reclaim enough steel to produce 13 million new vehicles. The man who invented the first modern cruise control couldn't even drive a car because he was blind! His name, says Smithsonian.com, was Ralph Teetor. Blinded at a young age by a knife accident, Teetor was inspired to create a speed control by a couple of things. One, the U.S. imposed a mandatory 35 mph/55 kp ... read more

You may have noticed sometimes on a hot and humid day, vapor will come out of your vehicle's vents when you have the air conditioning on. Is that something to be concerned about? Well, it depends. Sometimes that steam or vapor can be caused by water accumulating in the vent system after it has condensed. And sometimes water can pool at the bottom of a vent. When you turn on the blower mower, the air hits the water and may create steam or vapor that you can see in the cabin. One thing to check is if that vapor smells like anything. If it doesn't, that's a good sign. You may be able to run the fan for a while and the issue may just go away when things dry out. But moisture collecting in the ventilation hoses in a hot vehicle may be a breeding ground for mold, and that can have health consequences. There's another possibility. Ventilation systems often have drains to get rid of any accumulated water, and debris can sometimes clog them. A technician can ... read more

We all have joints in our own skeletal system, but did you know your vehicle has some joints of its own? One of the most important is called a ball joint. One of the interesting things is that it's somewhat similar to the ball and socket joints we have in our hips and shoulders. A ball joint allows two parts it joins together to move in more than one direction at the same time. Think about your wheels. They have to move up and down when there are bumps in the road but in sideways directions when you are making a turn. As you can see, the ball joints are important for your steering and handling to work correctly. Since ball joints do so much, they can wear out and become loose. When the ball wears down or the socket gets worn, there can be too much play in them. It can get so bad that the ball can come out of the socket and your wheel can fall off, a dangerous situation. Ball joints can also seize up. Some of them are sealed and never require maintena ... read more

Automatic transmissions rule. The old days of shifting your own gears are a thing of the past for most drivers. But automatic transmission trouble can be a big inconvenience for any driver if it comes at the wrong time in the wrong place. Here are some signs to look out for that may mean you are having transmission issues. When you are driving, your vehicle seems to slip in an out of gear without you touching anything. That's what some call, not surprisingly, a "slipping transmission." When your vehicle shifts from one gear to the next, you hear a loud "clunk." Transmissions are supposed to be nearly silent when they shift, so that noise is telling you something is wrong. If you notice there's a puddle of some fluid under your vehicle, your transmission could be leaking fluid. Try to figure out what color it is (try putting a piece of cardboard underneath to capture some of the fluid). If it is red or brown, that's a sign it could be transmissi ... read more
