What is a brake pad sensor BMW?
Your BMW brake pad sensor is what controls the “brake” light on your dashboard or iDrive system and lets you know how much life you have left in your brake pads.
Do you have to replace brake wear sensor BMW?
As brake pad wear sensors are designed to break, they should be replaced as a matter of course every time new brake pads are fitted. It’s also advisable to regularly inspect the sensors, in between pad changes, and replace where necessary.
How do brake pad sensors work BMW?
Electronic Pad Wear Sensors The wire connects near the brake pad very close to the rotor. Once the brake pad wears down past a certain point, the rotor will start rubbing up against the wire. Eventually, the wire will break and the change in resistance will cause the brake wear indicator to light up on the dashboard.
Can you reuse BMW brake sensor?
The front and rear brakes have the sensors on them. Whenever you change pads, they should be replaced. If the pads haven’t worn down to the sensor, you can reuse them. Make sure to inspect the sensor and wire for wear that could cause it to fail.
How many brake pad sensors do I need?
Typically two. One sensor is located on one front brake pad (left front).
Can you bypass brake wear sensor?
Re: Bypassing brake pad wear sensor? Yup, just short them out and reset. The car will assume the sensors are like new forever, and that you’re very easy on your brakes.
Can I drive with brake pad warning light on?
Is it safe to drive with the brake pad wear indicator warning light on? It is safe to drive with this light on for a short amount of time. Without any pad material, the brakes won’t stop the car as quickly so waiting too long is dangerous and increases the risks of getting into a collision.

Can I reuse my brake pad sensor?
Are brake sensors accurate?
First off the wear sensors are pretty accurate near the end of the pad life if the car is driven in a consistant manner (i.e. driven to work the same route each day). The brake pad wear system works in two stages.
How does the brake wear sensor work on a BMW?
This guide focuses only on the brake wear sensor and assumes you have already replaced the brake pads. BMW brake wear sensor is nothing more than a wire that runs at the tip of the sensor. 12-volt typically feeds the sensor at all times. Once the brake pads wear out, the sensor’s tip where the wire runs are cut as well, which opens the circuit.
Where is the sensor on the front brake pad?
One sensor is located on one front brake pad (left front). The second wear sensor is on the right rear brake pads. What is BMW brake pad sensor resistance?
How to replace brake pads on a BMW?
Have the pads replaced by the nearest BMW center.” Service Vehicle Symbol with a car on the lift. 5F15 DSC Brake pad wear, rear axle plausibility. Determine if you are replacing a front or rear brake pad wear sensor. Jack up the vehicle and remove the wheel. If replacing the front brake pad sensor, jack up the driver’s side wheel.
Can you remove the sensor from a BMW?
Many BMW owners choose to bypass (delete) the brake wear sensor by removing the sensor and installing a clip or cutting the sensor wire, exposing the wires and connecting them. This is known as short-circuiting the wire and emulates a “good” sensor but is not recommended.
