A Guide to Aftermarket Brake Pads for the 2018-2025 BMW Z4 (G29)
Tired of squealing brakes or excessive brake dust on your Z4's wheels? This guide will help you choose the right replacement pads.
- Always replace the single-use brake wear sensor when you replace your brake pads to ensure the warning system functions correctly.
- Switching to aftermarket ceramic pads from brands like Powerstop or Akebono can dramatically reduce the amount of brake dust on your wheels.
- Choose your pads based on your driving needs: OEM-equivalent for balanced daily driving, ceramic for cleanliness, or performance pads for aggressive driving and track use.
- Properly bedding-in your new pads by following the manufacturer's procedure is essential for quiet operation and maximum stopping power.
Signs of Worn Brake Pads on Your Z4
Your BMW is smart enough to tell you when it's time for new brake pads. A warning light will appear on your dashboard when the brake pad wear sensor is tripped. However, there are other signs you should pay attention to, as the sensor is only on one pad per axle.
- Squealing or Screeching: A high-pitched noise when you apply the brakes is often the first sign the pads are getting thin.
- Grinding Noise: If you hear a metal-on-metal grinding sound, stop driving immediately. This means the pads are completely worn away, and you are damaging the brake rotors.
- Brake Warning Light: The most obvious sign, indicating the electronic wear sensor has been triggered.
- Vibration or Pulsing: A pulsing feeling in the brake pedal or steering wheel when braking can point to worn pads or warped rotors.
Known Issues and Recalls
While there are no specific recalls for brake pads on the 2018-2025 Z4, BMW has issued recalls for related braking system components on other models, including an issue with the integrated brake module that could lead to extended stopping distances. Owners have also reported issues with aftermarket front brake pads not fitting correctly on 2022 and newer models, so verifying part numbers is crucial. A common complaint from Z4 owners is the large amount of brake dust produced by the original equipment (OEM) pads.
Choosing the Right Aftermarket Brake Pads
The factory brake pads on your Z4 are designed for a balance of performance and comfort, but they are known for creating a lot of dust. Aftermarket pads give you the power to choose what's most important to you, whether it's cleaner wheels, better performance, or saving money.
OEM-Equivalent Brands
These brands are often the original suppliers to BMW and offer performance nearly identical to the factory pads. They provide a great balance for daily driving.
- Textar, Pagid, ATE: These are all known OEM suppliers for BMW. Choosing any of these is like putting factory-spec parts on your car. ATE is often noted for producing less dust than other OEM brands.
- Brembo, Bosch: Well-respected brands that provide high-quality, reliable brake pads that meet or exceed factory specifications.
Low-Dust Ceramic Brands
For many Z4 owners, the number one goal is reducing brake dust. Ceramic pads are the best solution for this, offering clean operation and quiet performance with good stopping power for the street.
- Akebono: A highly recommended brand for low-dust ceramic pads, though finding the exact fit for the Z4 can sometimes be a challenge.
- Powerstop: A very popular choice among Z4 owners for significantly reducing brake dust while maintaining good pedal feel.
- Centric, Dynamic Friction: Offer quality ceramic pad options that focus on quiet, low-dust braking for daily use.
High-Performance & Street/Track Brands
If you enjoy spirited driving or occasional track days, a performance pad offers better high-temperature stability and bite, at the cost of more dust and potential noise.
- EBC Brakes: EBC offers different compounds like Greenstuff for spirited street use, Redstuff for a low-dust performance ceramic, and Yellowstuff for a street/track pad with a strong initial bite. 🎬 Compare EBC and Hawk performance pads in this video. Note that some users find Yellowstuff wears quickly with track use.
- Hawk Performance: Hawk's HPS 5.0 pads are a great upgrade for high-performance street driving with more stopping power than stock. Their HP+ pads are more aggressive and suitable for autocross or light track use but can be noisy on the street.
Don't Forget the Wear Sensor
Your BMW Z4 uses electronic brake wear sensors on the front left and right rear wheels. These are one-time-use parts. Once the brake warning light comes on, the sensor has been consumed and MUST be replaced along with the brake pads. Failing to replace the sensor will prevent the brake warning light from being reset.

Frequently Asked Questions
Do I need to replace my rotors with my brake pads?
Not always, but it's highly recommended. If your rotors are below the minimum thickness, have a large lip on the edge, or show signs of heavy scoring or vibration, they must be replaced. Installing new pads on worn rotors can reduce performance and cause noise.
What's the difference between ceramic and semi-metallic pads for my Z4?
Ceramic pads are quiet, produce very little, light-colored dust, and are great for daily street driving. Semi-metallic pads, which are closer to the OEM compound, offer better performance in a wider range of temperatures and have a stronger initial bite, but they create more dark-colored dust and can sometimes be noisier.
What is "bedding-in" and why is it important?
Bedding-in is a process of controlled stops to properly transfer a layer of friction material from the new pads onto the brake rotors. This process is crucial for optimal braking performance, preventing vibration, and ensuring a long pad life. Most aftermarket pad manufacturers provide specific bedding-in instructions.
Why are my new aftermarket brakes making noise?
Some noise during the first few hundred miles can be normal as the pads bed-in. High-performance pads are also naturally noisier than standard pads. However, persistent squealing could indicate improper installation, a need for more anti-squeal compound on the back of the pads, or an issue with the rotors.
Can I change the brake pads myself?
Yes, this is a feasible DIY job for those with mechanical experience and the right tools. However, the Z4 has an electronic parking brake that must be put into a special "service mode" using a diagnostic scan tool before the rear calipers can be retracted. Also, some owners report the front pads are glued in from the factory, making them difficult to remove the first time.

The G29 Z4 uses one front brake wear sensor (driver's side) and one rear brake wear sensor (passenger's side). The rear calipers require a scan tool to retract the electronic parking brake for service. Pad sizes may differ between sDrive30i and M40i models, and some 2022+ models have reported fitment issues with aftermarket front pads. Always verify the part number for your specific vehicle.
