Can a bad ABS sensor cause vibration?
A faulty ABS sensor has the potential to cause vibrations in a vehicle until it is properly serviced and replaced. In addition, a soft brake pedal can be an indicator of an issue with either the ABS sensor or the wheel speed sensor, although these are two distinct systems.
When experiencing vibrations or a soft brake pedal, it is important to address the issue promptly by consulting a professional mechanic for an accurate diagnosis and necessary repairs.
How does an ABS system work?
The ABS system is composed of two main components: the ABS module and ABS sensors located at each wheel.
Whenever the ABS module recognizes that the vehicle is skidding or has lost traction, it will activate a rapid pumping action on the brakes.
If the ABS control module is malfunctioning, there are several symptoms that can indicate a problem with it.
If you are experiencing any of these symptoms, it is advisable to have your ABS control module inspected and potentially replaced by a professional mechanic.
What happens if the ABS system is not working?
The sensors on the vehicle monitor the speed of the wheels and send a signal to the anti-lock braking system (ABS) module when it detects skidding or loss of traction. In the absence of a functioning ABS system, skidding or loss of traction is more likely to happen, especially during intense braking.
If the ABS control module is faulty or failing, there are several symptoms to look out for. These symptoms include illuminated warning lights on the dashboard, inconsistent or unresponsive braking, and unusual noises coming from the brakes. If you notice any of these signs, it is recommended to have the ABS control module inspected and repaired by a qualified mechanic.

What causes brake dust?
When the driver applies the brakes, the pressure exerted on the braking rotors causes tiny particles to be scraped off the brake pads. These particles, along with fibers from the semi-metallic parts of the brake pad, create the brake dust that becomes visible on car wheels.
The generation of brake dust is a result of the friction between the cast iron brake rotor and the brake pad. It is a common occurrence during the braking process.
If you notice brake dust on your wheels, it can be cleaned off. However, taking preventive measures such as regular maintenance and selecting brake pads with lower dusting tendencies can help reduce the accumulation of brake dust in the first place.
Does brake dust affect the performance of brake pads?
Brake dust may not directly affect brake pad performance, but it can lead to aesthetic problems and potential inhalation hazards. Thus, it is crucial to routinely clean the wheels and brake system components to prevent excessive buildup of brake dust.
What does brake dust look like?
Brake dust is formed from a blend of iron particles, carbon residue, and friction material. This mixture gives your wheels the appearance of being covered in road grime. The color of the dust can vary depending on the type of brake pad material used. European cars often have darker brake dust, as they prioritize quietness and performance in their brake pad materials.
Are the tires properly balanced, as an imbalanced tire can cause shaking when braking?
It is possible that there is an issue with the tire balance of your car, causing it to shake when you brake.
Additionally, other factors that could be causing the shaking when you brake include unaligned wheels, under-inflated tires, and worn-out suspension components.

Can a bad CV joint cause jittering?
The issue at hand is a minor one, as the jitter or slight shake is hardly noticeable and primarily occurs when driving at higher speeds. As time goes on, the shaking worsens and begins to occur even at lower speeds. It is important to note that this particular symptom, which is one of the 10 most common symptoms of a bad CV joint, can sometimes be mistaken for another problem.
Why do CV joints make a clunking noise?
CV joints that are in poor condition can often lead to unusual sounds. When the outer CV joints become worn, they typically produce a clicking or snapping noise when the vehicle is both turning and accelerating. In contrast, worn inner CV joints tend to create a clunking sound when the vehicle is either speeding up or slowing down. Understanding these noises and their associated symptoms is essential when diagnosing CV joint issues.
Can a worn CV joint cause vibration during acceleration?
The first step in diagnosing a CV joint noise or vibration is to determine the side from which the noise is originating and replace the corresponding axle shaft. If there is a worn inner CV joint, it can cause vibration specifically during acceleration. The "tulip" portion of the joint, where the roller bearings travel along worn tracks, makes the inner CV joint more susceptible to shuddering or vibration during acceleration.
Is a worn or damaged wheel causing the shaking when you brake at high speed?
There are several potential reasons for experiencing a shaking steering wheel when braking at high speeds. These include warped or rusty front brake rotors, deteriorated control arm bushings, a sticking brake caliper, improper wheel alignment, and unbalanced wheels.
