Oh, that’s not quite the response I was going for, so let me try again. Do I need to purchase new wear sensors with each pad change if I want to keep using the current ones?
If the replacement pads have a slot created for the sensors, you can reuse the brake wear sensors on them. If not, you’ll need to tie them to keep them out of the way. The brake pad wear sensors only need to be replaced if your brake pads have been worn down to the point where the plastic “nub” on the sensor has worn through and broken the metal strip within, indicating that your brake pads need to be replaced by opening the electrical connection. If you strain the cable while prying them out of the pads with a screwdriver or a pair of needle-nose pliers, you risk creating a short inside the cable, which will indicate that your brake pads need to be replaced.
Both the Hawk HP Plus and the High Performance Street brake pads have been utilized on my wife’s 335is Coupe. We use a Velcro strip to keep the wear sensors in place as neither has a hole for them. Strangely, new sensors were included with the Hawk pads, but you can still use the old ones if they are still functional.
The Pagid RS29s on the M4 feature a slot for the wear sensor, so it is not required to tie them out of the way. New wear sensors were not included with the Pagids.

BMW brake sensor replacement necessary?
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.
How much does a BMW brake sensor replacement cost?
Replacement brake pressure sensors for a BMW 328i typically cost between $254 and $265. Between $44 to $56 is the projected cost of labor, while the cost of parts is $210. Taxes and levies are not included in this range, nor are your particular model year or special location taken into account.
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.
Should I replace the brake sensor?
Since brake pad wear sensors are made to malfunction, they should always be replaced whenever new brake pads are installed. In between changing pads, it’s also a good idea to frequently inspect the sensors and replace them as needed. Heat from the brakes can harm the wire and clips over time.
BMW brake wear sensors: are they recyclable?
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.
How precise are the braking sensors on a BMW?
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 much does it cost to replace a brake 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
