The lifespan of brake pads for Mercedes Benz depends on many different factors such as each person’s driving style, time of use, environmental quality, etc. So, how to recognize that the Mercedes brake pads have been damaged? How to wear and replace brake pads? All detailed steps will be shared by experts from Eurocartool in the article below.
Why are brake pads important for cars?
Brake Pad Mercedes Benz is a type of brake pad specifically designed by Mercedes car company. Car brake pads are an important part of the car brake system, responsible for contacting the rotating part of the brake, creating friction to help reduce the rotation speed of the wheel when the driver steps on the brake pedal to slow down.
It can be seen that brake pads play an extremely important role on Mercedes cars in particular and other car models in general. If this part has a problem, it will put the driver in more danger on the journey.
Signs of worn Mercedes Brake Pads
Just like other vehicles, brake pads for Mercedes Benz will wear out due to constant friction during operation. At this point, there will be a number of signs letting you know it’s time to check and replace your brake pads. Include:
- Brake system error light illuminates: When the brakes on Mercedes are worn, the sensor that determines pad wear will contact the brake caliper and brake disc to issue a warning on the dashboard.
- Unusual noises coming from the brakes: Squealing noises when stepping on the brake pedal are a sign that the Mercedes brakes are severely worn and need to be replaced immediately.
- The car is difficult to control: When braking, if you feel that the car has a pulling force that causes the car to lean to one side when stopping, or feel that the car is jerking, you should have the brakes checked immediately.
- The feeling of pressing the brake pedal too lightly or missing: Normally, when pressing the brake pedal, it will cause the brake code to press close to the rotor, you will feel resistance when pressing the brake pedal. However, excessively worn brake pads will create the feeling of pressing the brake pedal too lightly or missing.
- The steering wheel vibrates when braking: When braking, if the steering wheel shows signs of vibrating, there is a high possibility that the brake pads are worn out.
- The car’s brakes won’t work: When the brake pads are worn out, the car’s brakes won’t work

How to replace brake pads for Mercedes Benz?
If you do not know how to replace brake pads for Mercedes Benz, you can see our instructions below.
Tools need to be prepared
Necessary equipment and tools for replacing brake pads include:
- Jack: Used to lift and support wheels.
- Torque lever and locking lever: Used to open and tighten the wheel locking lever.
- Wrench: Used to open the piston assembly.
- Parachute rope: Used to hang the piston assembly after removal.
- Piston press: Used to install pistons.
- Specialized cleaning solution for car brake pads and brake discs.
Steps to replace brake pads
Step 1: Remove the wheel
Use a car jack to lift the wheel, loosen the wheel’s nuts and bolts, and check the brake pads.
Step 2: Open the brake piston assembly
The back of the brake caliper has 2 rubber-covered brake bobbin bolts. You need to remove the bolts and use a screw to pry the piston assembly out of the brake assembly. Note that after disassembly, use a rope to tie it and hang the piston assembly somewhere next to it. Do not let the piston hang by the brake oil pipe because it can damage the oil pipe.
Step 3: Open the old brake pads – install new brake pads
Once you open the piston assembly, continue to open the old brake pads, then replace the new brake pads. Pay attention to the order of opening the brake pads, especially the mounting brackets, so that you can easily install new brake pads.
Step 4: Press the brake piston
Because the thickness of old and new brake pads is different, the new brake pads will have difficulty getting into the piston position when installed. Therefore, it is necessary to use a piston rod to compress the piston back to its original position so that it can fit the new brake and brake pads.
Step 5: Reinstall the piston and wheel assembly
Reinstall the piston according to the correct brake mechanism, add oil to the brake bobbin bolt. Finally reinstall the wheel.
What should you pay attention to when replacing brake pads?
The process of replacing brake pads is quite simple and you can easily do it. However, we will give you some notes after replacing the brake pads to help this part work longer.
Choose the appropriate type of brake pads
For each type of vehicle, there will be different types of brake pads for Mercedes Benz specifically designed to suit the vehicle’s operating needs. For example, for racing cars to meet the continuous, high-intensity working process, the brake structure must be different from normal motorbikes and be equipped with a separate cooling system.
Therefore, you should pay attention to the vehicle’s technical specifications to choose the appropriate brake pads.
Immediately after replacing new brake pads for Mercedes Benz, or performing Trail Braking, this helps create the correct heat generation process when braking, it also transfers a thin layer of material from the pad to the disc, enhancing adhesion between the two surfaces. In the case of new pads and old discs, Trail Braking is the step that helps the pads adapt to the disc surface.
You should brake lightly for the first 100 km to increase the life of the pads. Absolutely do not use old discs with new discs, because scratches on the old discs will damage the new disc surface.
Check for warping and air release
After replacing the brake pads for Mercedes Benz disc, lining and oil, you should perform the process of “bleeding” the brake system. Because there is air mixed in the brake fluid and oil pipes (air gets mixed in when the brake pads wear out, when the amount of brake fluid is low), making the brakes less effective.
Above are detailed instructions and notes on replacing brake pads for Mercedes Benz. The process seems simple but directly affects the experience and safety of the driving journey.
