For your BMW E60 5-Series, replacement StopTech brake pad wear sensors are now accessible. When having your brakes serviced, replace your outdated, useless sensors with these brand-new, premium StopTech sensors.
What Makes New Sensors Necessary? Although your BMW features eight brake pads, only the inner pads on the driver’s side front and passenger rear are actually checked for wear. The rotor will chew through a tiny plastic bump on the sensor when a pad has worn down to less than 2 millimeters or has any leftover frictional material, slicing the wire in half and causing your car to display a warning light on the dash. This usually serves as a warning that new pads will soon be required. A sensor, however, must be replaced with a fresh one after it has been used and a warning has appeared.
How many braking sensors are there in a BMW?
One sensor is for the front and the other is for the back. Is your dash lit up by your brake light? If not, your existing sensors can be reused; however, if you do, you must replace either one or both. There are two: one for the rear passenger and one for the front driver side.
Are sensors present in BMW brake pads?
Recent releases from numerous German manufacturers, notably BMW, have a two-stage pad wear sensor (See Figure 3). The driver can receive more information from these sensors than just a worn brake pad alert. They can actually calculate the remaining mileage of a brake pad.
How does a brake pad sensor for a BMW operate?
Electronic brake pad wear sensors are now installed in a wide range of contemporary vehicles, especially European vehicles. They inform you when it’s time to replace your brake pads with a brand-new set. But how do they function? And how frequently do they require replacement?
The conventional metal squealer tabs that are more frequently used in braking systems are replaced by electronic brake pad wear sensors. When the pads have reached the end of their useful life, these tabs continue to function by rubbing against the rotor. It alerts the driver that the brakes need maintenance by emitting a loud screech.
In addition to the scream, this has the drawback that most drivers tend to ignore the warning since they believe the sound will ultimately stop. Electronic brake wear sensors take care of this noise and provide a more precise indication of the remaining life of the brake pads.
Once the brake pad has worn sufficiently for the sensor to make contact with the brake rotor, the wear sensors are intended to break or complete a circuit. The dash will typically illuminate with a warning light when the brake pads need to be changed.
Basic brake wear systems typically implant a sensor inside the inner brake pad at each corner of the car. However, from vehicle to vehicle, the number of wheels with sensors and their positioning on the brake pad can differ. These systems merely have a wire loop that is conducting a little amount of current.
Brake wear sensors in the modern day have a few new tricks up their sleeves. Not only do they alert the driver when brake maintenance is necessary, but they can also predict how long your existing brake pads will last. These ruse sensors, sometimes termed as twostage sensors, operate with two parallel resistor circuits at two depths. The resistance in the sensor rises as the initial resistive circuit fails. In order to determine how much life is still left in your brake pads, this is utilized to collect data such as wheel speed, brake pressure, brake disc temperature, brake operation time, and mileage. This is typically shown in the information center of your automobile or as a warning light that changes color as the pad ages. The circuit becomes open when the second circuit is disrupted. This sets off the brake service indicator light, alerting you that it’s time.
Braking pad wear sensors are not reusable because they are made to break or complete a circuit by making contact with the brake rotor. With each change of brake pads, wear sensors for the brakes should be updated. To fit a variety of automobiles, Bendix offers brake pad wear sensors. For the majority of common makes, our Bendix Euro+ Brake Pads also include all required clips, shims, and sensors, so you’ll be ready for your upcoming brake pad replacement. At your next service, request Bendix brakes from your mechanic.
The majority of popular makes and models are guaranteed to fit with Bendix’s brake wear sensors. Visit to determine if your local Bendix stockist has brake sensors that will work with your vehicle.
The accuracy of the BMW brake pad sensor
It is very accurate if installed properly since it needs to be changed when the minimum level is reached because it wears out. You shouldn’t be concerned until your car shakes noticeably when you brake.
How many braking sensors are there in a BMW x1?
Brake pad wear sensor for the front or back. From the menu, choose Part Location. Buyers should be aware that one sensor is used for the front and one for the back.

Are new BMW brake sensors required?
The “brake” light on your dashboard or iDrive system is controlled by your BMW brake pad sensor, which also informs you of the remaining life of your brake pads. The sensor is mounted to the brake pad; as soon as the brake pads are completely worn down, the sensor’s tip breaks, tripping the wire and turning on the dashboard light. The brake pad sensor error codes are as follows when using an OBD scanner:
5, 5, 6, 5, 14, 5, 15, and 6F12
Every time you change your brake pads, you should also replace the brake pad sensor. The sensor does not need to be changed every time, but failing to do so could lead to erroneous readings of the amount of life left in your pads and a persistent notification on your dash/iDrive system. The only way to get rid of the light once it appears on the dash is to either swap out the sensor or bypass it, which will stop it from reading the pad life.
Is the BMW brake sensor reusable?
Nope. If not carefully remove them and reinstall them, they only need to be replaced if they have been activated. Nope. Unless they have been activated, they merely need to be replaced; otherwise, carefully remove them and reinstall.
How many sensors measure brake wear?
This turns on the warning light that signals that the brakes need to be serviced. While many brake pad wear systems have a sensor on the inboard pad at each corner of the car, the exact number might vary based on the braking system’s design, from one to four.
Are sensors present on each brake pad?
One corner of the car often has sensors in the front and back to measure the wear of the brake pads. Because the inboard brake pad normally wears out the quickest, the sensors are installed on it. For every inboard brake pad, there are more sensors on higher-end systems. Every pad may include a sensor on more exotic automobiles with carbon or ceramic rotors.
The sensor’s resistance value was known in earlier systems. A rectifier circuit in the instrument cluster sensed an open circuit when the resistance reached 2,000 ohms or above and turned on the light. Physical harm and corrosion at the connector are the most frequent causes of failure for these circuits.
In some systems, the sensors are connected in series. In this instance, when the circuit loop is disrupted, the system is unable to identify which brake pad has been overused. This can make open circuit diagnosis challenging. To pinpoint an issue, you must check for continuity at the connectors.
Why would a brake pad sensor be used?
The Brake Pad Wear Sensor, often known as the brake wear indicator, is a safety device fitted to many automobiles that alerts the driver if the brake pads’ thickness drops too low and their usable life is getting close to the end. As brake pads deteriorate, Brake Pad Wear Sensors are intended to “fail.” When the pads need to be replaced or when the vehicle’s warning light comes on, they should be changed.
How many ABS sensors are there in a car?
The number of ABS sensors in a vehicle can range from one to four, depending on the sort of braking system it has. Mechanism: The ABS sensor typically comprises of a coil-encased magnet and a toothed ring.
Do brake sensors need to be used?
The sensors will turn off the motor’s power in emergency situations where you quickly brake. You might not be as quick to squeeze the brake levers when pedal assist systems are present. This may need to be a dual safety feature in normal brakes. In most cases, hydraulic brakes are strong enough to stop you if you become anxious.
You can test your e-bike without them and without putting the cut-off in order to determine whether you require it to be installed.
What is the price of a braking sensor?
Aftermarket pad sensors can cost anything from $5 to $100. Additionally, you should budget an additional labor expense of $70 to $100 if you decide to hire a professional brake work.
A new sensor can also cost more due to a number of factors, including:
- Make and model of the vehicle
- Brand and series of brake pad sensors
- Warranty for brake sensors
- Sensor pad length
- elements of worn sensors
- in which you reside
Where are the braking sensors?

When should BMW brakes be replaced?
How durable are BMW brake pads? Depending on how you drive, BMW brake pads typically last between 30,000 and 70,000 kilometers. You’ll need to have an examination more frequently if you commute in heavy traffic and use your brakes frequently.
What symptoms indicate a malfunctioning brake sensor?
There are other parts of your car than the antilock brakes that depend on the ABS wheel speed sensor for optimal operation. Data from the ABS sensor may also be used by the stability and/or traction control systems for stability control, hill-start assistance, and a number of other purposes. Those systems might not function if the ABS wheel speed sensor fails, and they will remain disabled until a new sensor is installed.
