What to do when the brake pad wear indicator warning light is on?
What to do when the brake pad wear indicator warning light is on. If the light comes on, you should bring the vehicle to a certified technician to have the brakes replaced. More than likely, the light will shut off with the new pads installed. However, any issues with the sensors themselves will cause the light to turn on.
Why is my anti lock brake light on?
The anti-lock brake system is a complex configuration of computers and sensors. When all of the components are working in perfect harmony, it ensures a quick, reactive system that can improve braking control under all surface conditions. Faults in this system are often first indicated by illuminated lights in the gauge cluster.
How does a brake pad sensor work on a car?
The first is by using a small sensor embedded into the brake pad material itself. As the pad wears out, the sensor will eventually come into contact with the rotor which completes a circuit and turns this indicator light on. The second method is a position sensor that measures how much the pads have to move before the brakes are applied.
Why does the anti lock braking fluid drop?
The braking fluid has a lot to do with controlling the braking pressure within an anti-lock braking system. There is a braking fluid reservoir which holds the fluid of the anti-lock braking system. Sometimes there could be a leak from this reservoir which will cause the fluid levels to drop.
Where is the brake fluid level sensor located?
A fluid level sensor is located in the brake master cylinder fluid reservoir which monitors this level. With the hood open locate this reservoir and check the fluid level. There are only two reasons for this fluid to be low.

What makes a brake warning light a warning light?
The brake warning light is a multi functional light which is connected to three different monitoring devices. The first is the brake fluid level sensor in the brake master cylinder.
What causes a brake caliper to leak at the rear?
The first is a leak in the system which could be at the rear of the master cylinder. A brake caliper seal has failed or a rear wheel cycling is leaking. More obscure problems include a brake flex hose or one of the steel lines has rubbed through on the frame.
How can you tell when your brake pads need to be changed?
Signs of even brake pad wear are indicated by equal amounts of material on both pads for each tire. Tip: You should seek brake pads with wear indicators. Wear indicators let you know when it is time to change your brake pads either by sound, sensors, or by visually inspecting the indicator on the brake pad.
What does reset the brake pad light do?
It’s been a while now so my memory fades, but I don’t recall doing anything to clear the light, but I replaced the sensors at the same time the pads (and rotors on occasion) where replaced. Replacing the sensor does reset the light.
What does it mean when your brake pads are out of alignment?
Brake pads that show uneven wear generally are out of alignment, and depending on the wear pattern this type of wear could mean a variety of things. Understanding the wear pattern on your brake pads lets you easily find a solution to fix any existing problems.

What happens when the brake pads wear on a car?
As the brake pads wear, the fluid in the reservoir is displaced, as it takes more fluid to move the brake pads towards the brake disc. Some vehicles are also equipped with brake pad wear sensors.
Is it safe to drive with brake pad light on?
It is safe to drive with this light on for a short amount of time. As mentioned earlier, the light will come on when you still have some brake pad material left, but if you wait too long and continue driving, you will run out of material and damage the rotors.
What to do when the brake pad wear indicator warning light is on. If the light comes on, you should bring the vehicle to a certified technician to have the brakes replaced. More than likely, the light will shut off with the new pads installed. However, any issues with the sensors themselves will cause the light to turn on.
Why are there brake lights on my dashboard?
Some common brake lights that can show up on a dashboard include: This light is a warning that brake pads are getting too worn and should be replaced soon: If these lights go off and on repeated or when you turn, it can mean to check the brake fluid level in the master cylinder:
How can I tell if my brake pads are wearing down?
When the brake pads wear down to a certain point, typically around 15 percent material remaining, the pads contact the sensor and the light illuminates. Step 1: Check for a Brake Pad Warning Light. If your car has this special brake pad sensor, you will see this symbol illuminated on your dashboard if your brake pads material has worn down.
What to do if your parking brake light is still on?
Tip: New vehicles may be equipped with an electronic parking brake that is engaged and released simply by pressing a button on the dashboard. The button is marked with the same symbol as the parking brake light on the instrument cluster. Press this button to release the parking brake. Step 2: Check to see if the brake light is still illuminated.
How to troubleshoot a Mercedes Benz with a brake light?
Park your vehicle and set the emergency brake. Turn the key to the “on” position where you will see all the lights come on the dashboard. Release the emergency brake and see if the light goes out. Repeat setting the brake and releasing the brake a few times.
What causes a brake warning light to illuminate?
A brake warning indicator can illuminate for multiple reasons including: 1 A burnt out brake light 2 Anti-lock brake (ABS) sensor malfunction 3 Brake pads low on material 4 Low battery voltage 5 Low brake fluid in the reservoir 6 Parking brake stuck on
What happens if you dont have a brake pad?
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. As always, our certified technicians are available to help identify any issues you may be experiencing with your brakes or wear indicators.
Can a W202 brake sensor be removed without warning?
If so, it uses a single-wire sensor and if it is removed, then you will get no warning. On newer models, the sensors use two wires and if removed, you will get a warning until they are replaced. Yes, it’s a W202.
Where are the brake sensors on a Mercedes Benz?
Can it be done with the car sitting in the driveway (not jacked up.) You will need to remove the wheel to get to the sensors, but once you’ve done that, you should see them sticking out of the back of the brake pad. They just slide right into place.
Are there front brake pads that need to be replaced?
Yes, the front pads have been replaced, along with the front rotors. I took the car to PrecisionTune and they did the work, using parts I bought. Sadly, I didn’t know about the sensors; otherwise I’d have bought them along with the other parts. The warning light is NOT on and PT said the sensors needed to be replaced.
How does the brake wear sensor work on a Mercedes Benz?
The brake wear sensors have two wires running to contacts embedded in plastic within them. The sensors are triggered when the pads (and thus the plastic of the wear sensors) wear down to the point where the two wires feeding into / out of them created a CLOSED circuit (or short) through the brake rotor.
What happens when brake pads and sensors are replaced?
Once the pads and sensors are replaced the brake wear warning should disappear almost immediately. You might need to turn the ignition on and off a few times, but that’s it. Oh. 125K miles on what I think were the original pads and rotors, although I can’t be sure because the car had 85K miles on it when we bought it.
What does the ABS warning light on a Mercedes mean?
If the ABS warning light is also illuminated this signals that the braking system has malfunctioned and your brakes may not work properly. In this case the Electronic Brake Force Distribution (EBD) warning light may also be illuminated. Can I still drive with my parking brake and brake fluid light on?
