Rating of the best brake pad wear sensors of 2022

Pad wear sensors inform the driver about the current state of the vehicle's braking system. They are installed one at a time on the front and rear axles of a foreign or domestic car to indicate to the vehicle owner the need to replace the part. Their price, as a rule, varies from 100 to 8000 rubles.

In our review, we will provide recommendations: what to look for in order not to make a mistake when choosing a product, which company model is better to buy. We will get acquainted with popular manufacturers, a description of their devices, and we will orient you at an average price.

Types of signaling devices, how to choose them correctly

When the brake pedal is depressed, the pads of the machine contact the discs or drums, slowing down or stopping the rotor attached to the wheel hub. When they wear out, you will hear a piercing squeal, this is triggered by a mechanical sensor, which is an ordinary metal plate. However, if a modern mechanism is installed, this sound will not occur, the warning light will warn the driver that the system needs to be replaced. Mechanisms fail simultaneously with brake pads.

These electrical devices are resistors that connect to the computer module. They are attached to the pad, maintaining constant frictional contact with the surface of the brake rotor. During their installation, a spring clamp is used to hold the part in place with a force of more than 30 newtons. The car must be equipped with software, algorithms for precise wear control.

In addition to warning, the mechanism will help to estimate how many kilometers are left before changing the pads. Sensors are single or multi-stage, the latter have a chain of resistors located at different heights in a plastic case. When the first line of contacts breaks, the vehicle information center starts calculating the remaining pad life. This uses various inputs such as mileage, wheel speed, pressure, burst temperature, and brake system time.

In the automotive industry, there is a growing demand for the safety of vehicles in various weather and environmental conditions.Alarms are important to prevent accidents, reduce machine maintenance costs. Advantages of using the device:

• informs about the state of the pads;
• Accurately predicts service life using an algorithm, eliminating the need for visual inspection of the system;
• improves the reliability of the brakes, warning the driver about the need to replace them;
• prevents significant wear of the rotors.

Most older systems had sensors on the inside of the block. They differed depending on the number of wheels and their location. In the 1970s, the devices were simply a hoop of wire that circulated a small amount of current. These designs had a limiting resistance value. When it exceeded 2000 ohms, the rectifier circuit on the dashboard detected an open contact and turned on the warning light. The most common failures in structures of this type were physical damage, corrosion of the connector.

On some European passenger cars, such as Mercedes-Benz models, rear pad life is measured using the electronic parking brake module. The system is controlled by a stepper motor in the caliper or a motor that drives the cables. It will count the number of revolutions required to engage the rear pads. Some designs perform this measurement at ignition start.

It is recommended to change removable sensors regularly. Over time, heat can damage the wiring and clip holding the switch. These devices are cheap compared to the cost of repairing a car in the event of a brake failure. Many top last sets include them as part of a complete set.

Don't forget to reset the brake life indicator.In some vehicles, this can only be done using the Driver Information Centre. Other vehicles may require the use of a scanner. Also check the connector, corrosion can cause a change in the resistance of the sensor. Make sure the seals inside are secure - some technicians use dielectric grease.

If you look at the wiring diagrams of the brake systems of some luxury car brands, you will see that they have a connection to the telematics module and the CAN bus. Therefore, the estimated life can be shared with the original equipment manufacturer and possibly a local dealer so that the owner of the vehicle can make an appointment to service the machine. This level of communication has recently drawn criticism as it leaves the system open to cyberattacks.

There are two ways to operate the electrical mechanism, which is a closed wire that signals the driver that he is in contact with the rotor. One option is to send a message - if the rotor touches the sensor, this causes a change in resistance, as a result, the response of the system. The second way is when the rotor cuts the wire, breaking the circuit. Again, this causes a change in resistance, and as a result, the lamp fires. The first way "closes" the chain, and the second - "breaks" it.
