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

Today's vehicles have some pretty amazing technology in them, including a computerized braking system we all pretty much take for granted these days. Antilock brake systems (ABS) have been around for years but they help drivers stop in much shorter distances reliably than ever before. When you see your ABS warning light come on, it's important to find out what's causing the problem. It's a safety issue. Often the problem when the ABS light comes on is a faulty wheel speed sensor. (In some cases the traction control light will also come on, perhaps because of a non-working wheel speed sensor.) Your vehicle uses the speed sensors to measure the rotational speed at each wheel. That sensor sends the speed data to a computer that can then adjust braking power and prevent your wheels from locking up. If any of the wheel speed sensors isn't working right, the ABS warning light will go on and the vehicle's computer will turn off the antilock brake system. You'll s ... read more

The brake rotor, or disc, is attached to your wheel. The brake pads rub on the rotor to slow your car when you are driving in San Diego.Rotors can warp, crack or become misaligned. They can also be damaged by worn out brake pads that scratch grooves into the surface. These conditions result in less contact surface for the brake pads, leaving you with reduced braking power.Over time and miles, rotors can also wear down below safe specifications. It is important for San Diego drivers to know that simply replacing brake pads on a wheel with a bad rotor will not solve the problem. Depending on their condition, rotors may be resurfaced or replaced.Brake noise or a pulsation in the brake pedal are signs of potential brake problems that should be addressed right away.

If that little brake warning light pops up on your dash, do you know what it means? Well, if you said no, you wouldn't be alone. You know it has something to do with your brakes, but exactly what? You're not sure. One of the reasons is that it could mean a lot of different things. It could be something simple, like you put your parking brake on and forgot to take it off. Easy fix, you're on the road in seconds. Or, it could mean there's something wrong with your anti-lock brake system. That is a pretty complex symphony of speed sensors, computers and wiring, and sometimes things get a little out of whack. You could have a defective sensor or some wiring may have gotten damaged or come loose. A trained technician at John's Automotive Care with special equipment can sort it all out. It's also possible you have low brake fluid. That could be caused by a number of things. One simple reason is that your brake pads have worn down. Replacing them could solve the problem. Another possibility i ... read more

Let's talk about something critical for all San Diego drivers: your brakes. Your vehicle is heavy, and it takes a lot of muscle to bring it and your passengers to a safe stop – so everything needs to be in good working order. Here's an explanation on how your disc brakes work: The wheel hub keeps your wheel attached to your vehicle. The brake disc – or rotor – is attached to the hub and rotates with the wheel as you drive around San Diego. Your brake pads clamp onto the rotor to slow the wheel.The brake caliper straddles the rotor and squeezes the rotor to slow it down. The calipers contain brake pads which press on the rotor when you put your foot on the brake. The brake piston causes the calipers to squeeze and release as you use your vehicle brakes.Your brake pads start to wear the first time you step on the brakes. Eventually ... read more
