At one time or another, most drivers honk their horn at someone who might be texting at a stoplight or not paying attention when they're driving. But what happens when you tap on your horn and all of a sudden it won't quit? Everyone's looking at you like you're an angry jerk and all you want to do is turn it off! It helps to know the basics of what's happening when you honk your horn. There's a switch in the steering wheel, of course, and when you press on it, it sends power to a relay which then energizes the horn. Bingo. Sound. When the horn sticks on, one of these parts or the wiring has developed a problem. With the ear-splitting noise inside your cabin, it may be hard to keep your cool, but do your best to stay calm. Try pushing the horn several times; it may un-stick the switch if you're lucky. If not, there are a couple of things you can try. First, if you can, pull your vehicle off the road and into a spot where you're not disrupt ... read more

You notice when your smartphone's battery starts to go weak on you. It runs out of juice faster than it did when it was new. Bet you pay attention to that pretty closely. Unfortunately, many of us don't pay the same attention to the battery in our vehicles. If your battery got you through the cold-weather months, you might be thinking you're all set until next winter. But you might be surprised to learn this: Hot weather is harder on a battery than cold weather. (Note: we're talking about a conventional vehicle here, not an all-electric, plug-in one.) The way your vehicle's battery holds a charge is that it has chemicals inside it, and they react with each other to produce electricity. A vehicle battery discharges electricity and then needs to be recharged. Unlike your smartphone that you plug in each night to charge, the way a vehicle's battery gets recharged is by using the mechanical energy of the engine. It's a pretty cool system that's been arou ... read more

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

So you thought you only had two brake lights. Look again and you'll see one in the center at a higher level than the two on either side of the vehicle. They're sometimes in the inside of the vehicle behind the back window, or they could be in the deck lid, on the roof or on the spare wheel carrier, But why is that third brake on your vehicle? Experts say it helps prevent rear end collisions. Tests done by installing the third brake light in taxis and fleet vehicles showed fewer rear end crashes in the ones that had the extra light. The third brake light was mandated in new passenger cars in 1986 in the US and Canada. The requirement was added to new light trucks and vans in 1994. Sometimes it's difficult to know if your third brake light is even working. Many vehicles have bulb warning systems that alert you to non-functional bulbs, but not all do. Your vehicle service facility will often check to see if all your turn signals, taillights and headlights are worki ... read more
