4 braking problems that you can diagnose by listening alone – Jalopnik

Brakes are an important part of your car, because you are faced with stopping safely and on time. However, brake components carry over time, especially brake pads in the case of disc brakes and brake shoes for drum brakes. It is crucial to identify the wear of components and replace them on time, because ignoring it can lead to a step -by -step effect of malfunctions.

Manufacturers offer a replacement time line for braking components, such as other autocomonents. Depending on your driving style, however, your brakes could see accelerated wear, which requires replacement well before the recommended timeline. Fortunately, moving parts are broadcast a sound, and in the case of brake components they use friction to slow down vehicles, of which a by -product is heat and noise. A worn or damaged brake component will broadcast a unique sound.

If you know these sounds, you can better diagnose specific braking problems and correct them before they cause further damage or, even worse, brake failure. We will mainly focus on vehicles with disc brake, because most modern vehicles have stopped using drum brakes. Different braking sounds indicate different braking problems. Some common are grinding, squeaking, pounding, rattling, clicking and squeaking.

One of the most obvious tells is a grinding sound or the sound of metal-on-metal scrape. It is a sound that you not only hear, but also feel through the steering wheel in the case of the fronts. A common reason for this is worn brake pads. A brake pillow contains a composition of frictional material with a metal back plate that offers structural support. The composite friction material rubs the metal disk and the friction stops the vehicle. Different brake pad materials exist, such as ceramic and organic brake pads. The composite friction material is designed to carry away, and as soon as it does, the metal back plate rubs the metal disk, leading to a grinding sound. This metal-to-metal contact can damage the brake disc, which is much more expensive to replace than the brake pads. The solution is to replace the brake pads as quickly as possible.

Another reason for the grinding sound can be due to strange objects such as a small stone that is housed between the brake pads and disc, so that it grinds the last one. It is a simple solution and requires no replacement of brake components. If you hear a rub noise while you drive your car after it has been quiet for a long time, peace is probably built up on the surface of your brake disc. Driving around in traffic and braking in between must come off the rust and the resulting sound.

A squeaky sound during braking is often diagnosed with low quality brake pads. In addition to poor brake performance, low quality brake pads usually have a squeaky sound. Another reason can be the braking layer indicator on the pillow that comes into contact with the metal disk. Also called metal squealers, these are small tabs on the pads that give a high squeak, which indicates that it is time to replace your brake pads. A chirping sound that is comparable to a squeaky sound. It may be due to a strange object, such as a loose brake hose, which comes into contact with the rotating wheel or disc. A good way to identify this problem is by checking whether the intensity of the tjilpen sound changes with vehicle speed.

A moaning or cracking noise is not necessarily caused by a braking problem. It may be due to worn wheel bearings or suspension components. Braking can cause this sound if the suspension components also move during delay, the suspension components. Get the vehicle on a connection and turn the wheel to check for lower sound. If that is not the problem, check suspension components such as bullet joints and control arms. If you hear a hissing sound while braking, this may be due to a vacuum leak in the brake booster. A damaged vacuum hose or a torn aperture would cause air to leak, causing the sizzling noise. Another way to diagnose it is the loss of brake boost, which makes the brake pedal feel abnormally stiff.

A resounding or banging sound can be due to a loose caliper bolt that can solve the problem. A ratchet problem can be diagnosed as incorrectly installed brake pads, calipers or anti-rattle signs, causing the brake pads to move while braking their original position. This is a serious problem that can lead to poor brakes, the vehicle that pulls to one side under braking, or even brake failure. A rattling sound can also be due to crooked disc brakes, which touches the brake pads against parts of the disc. This will also lead to vibrations that felt in the brake pedal and the steering wheel. In this case, a disc can pop up or replace again. That said, banging or rattling problems are more due to loose suspension components than brakes.

An unusual sound is a moaning or low moaned sound that is accompanied by a low string capacity. This may be due to glazed brake pads, where the brake pads have a mirror -like, shiny surface instead of a rough friction surface. This is done through frequent hard braking or driving on the brake pedal, which overheats the surface of the brake block to a point that deteriorates and passes. Although a temporary solution is to sand the glazed surface, it is advisable to completely replace the brake pads.

Another unusual noise, but a found in ABS-out vehicles, is a fast grinding sound when ABS starts. Although this is an indicator for the correct working of ABS, the phenomenon is reserved for high-speed brakes or brakes over surfaces with a low traction. If it is a common event and even happens at low speeds, this may be due to a defective ABS or wheel speed sensor.

Brakes are vital parts of your car, and although it is one thing to diagnose problems with your braking system, it is another to prevent these problems from appearing. There are some preventive steps to ensure that your brakes stay in top condition. It starts with the following driving habits that ensure that your brakes have a long, consistent life.

First avoid braking hard. Slamming on the brakes as your life depends on, puts you exaggerated pressure on your brake system, especially your brake pads (shoes in the case of drum brakes). This leads to excessive wear, which requires a premature replacement of the brake pads. If you keep a safe distance from the car ahead, it is better to plan in emergency brake scenarios, giving you enough time to respond and stop the car gradually. Gradually braking goes a long way in preserving your brakes.

The best way to keep your brakes is by using them as little as possible. Although it may seem stupid, anticipating your stops and the lifting of the accelerator pedal gradually slows your vehicle to a point where it can stop automatically. Motor brakes is your friend and can save you if your brakes fail on highway speed. Learning to use it together with your brakes increases your brake efficiency and life exponentially. Avoid holding it while braking, because it simply releases your vehicle from hood and actually increases the speed of your vehicle. Be careful, however, you can also do the braking of engines wrong. Other hygienic driving tips keep your foot off the brake pedal. A constant pressure on your brake pedal, no matter how light, ensures that the brake pads rub with the disk and long -term exposure leads them to overheat, which causes excessive wear.
