A Guide to Replacing Disc Brake Pads on Your 1999-2003 Volvo S40
Tired of brake dust and noise? Find the right aftermarket brake pads for your first-generation S40.
- Choose quality aftermarket ceramic pads from brands like Akebono or Bosch to reduce brake dust and improve pad life compared to OEM.
- A special caliper wind-back tool is required for replacing the rear brake pads; a C-clamp will not work and can cause damage.
- A hard brake pedal, especially when cold, is a known S40 issue likely caused by the vacuum pump system, not the brake pads.
- Always consider replacing brake rotors at the same time as the pads for the safest and most effective braking performance.
Is it Time for New Brake Pads?
Your Volvo S40 will give you clear signs when the brake pads are getting low. Ignoring them can lead to more expensive repairs, like needing to replace the brake rotors. Watch out for these common symptoms.
Common Failure Symptoms
- Squealing or Screeching: A high-pitched noise when you apply the brakes is often the first sign. This sound comes from a small metal tab called a wear indicator hitting the brake rotor.
- Grinding Noise: If you hear a deep, metallic grinding sound, stop driving as soon as it is safe. This means the pads are completely worn away, and the metal backing plate is grinding against the rotor, causing serious damage.
- Vibration or Pulsing: A pulsing feeling in the brake pedal or steering wheel when braking can point to warped brake rotors, which often happens when worn pads are used for too long.
- Pulling to One Side: If your car pulls to the left or right when you brake, it could mean the pads are worn unevenly or there's an issue with a brake caliper.
- Longer Stopping Distances: If you notice it's taking longer to stop than it used to, your brake pads may be worn out and unable to create enough friction.
A Note on a Common S40 Brake Issue
Some 1999-2003 S40 owners experience a very hard brake pedal, especially when the car is cold. This often makes the car difficult to stop. This is usually NOT a problem with the brake pads themselves, but rather a known issue with the brake vacuum pump or its associated switch and hose assembly failing. If you have this symptom, it's important to have the vacuum system checked by a mechanic, as new pads will not solve the problem.
Choosing the Right Aftermarket Pads for Your S40
The original Volvo brake pads are known for being soft, providing a good pedal feel, and being quiet. However, they also create a lot of dark brake dust and can wear out relatively quickly. High-quality aftermarket pads can offer a significant improvement in dust reduction and lifespan, often at a lower cost. Here’s a breakdown of available brands.
Brand Tiers
- OEM-Equivalent: These brands aim to match the performance and feel of the original factory pads. They are a safe, reliable choice for daily driving.
- Bosch: A well-regarded brand that often manufactures parts for Volvo. Their QuietCast line is a popular choice that balances performance and low noise.
- Pagid: Another brand mentioned by owners as a solid OEM-equivalent option.
- Genuine Volvo: These are the pads you'd get from a dealer. While they guarantee a perfect fit, they are often re-branded parts from manufacturers like Bosch or ATE and are typically the most expensive option.
- Low-Dust / Upgrade: These pads use different materials, like ceramic, to reduce brake dust and often increase pad life.
- Akebono: Highly recommended by owners for their ceramic pads, which offer a strong bite, long life, and significantly less dust than OEM pads.
- Powerstop: Often sold as a kit with rotors, Powerstop's carbon-fiber ceramic pads are designed for low dust and improved stopping power over stock pads.
- Performance-Oriented: For drivers who want a more aggressive bite and performance, though sometimes at the cost of more noise or dust.
- Brembo: While a top name in high-performance brakes, their standard replacement pads for the S40 are considered a solid, slightly better-than-OEM option rather than a full race pad.
- EBC Brakes: Offers a range of pad compounds from daily driver to performance-focused.
- Raybestos: Known for making high-quality brake components with a focus on safety and performance.

Pro Tip: Replacing Rotors
It is almost always recommended to replace your brake rotors at the same time as your pads. New pads on an old, uneven rotor surface can cause noise, vibration, and reduced performance. Since the labor to access the rotors is already done during a pad change, replacing them together is cost-effective and ensures the best braking performance.
Frequently Asked Questions
Do I need special tools to change the brake pads on my S40?
For the front brakes, you only need standard hand tools. However, for the rear brakes, you will need a special brake caliper wind-back tool. The rear caliper piston must be rotated and pushed in at the same time to retract it. Using a C-clamp like on the front brakes will damage the caliper.
What's the difference between ceramic and semi-metallic pads?
Semi-metallic pads contain metal fibers that help dissipate heat and provide a strong bite, but they can be noisy and dusty. Ceramic pads are made from a denser material that produces a finer, lighter-colored dust that doesn't stick to wheels. They are known for being very quiet and long-lasting, making them a great upgrade for a daily driver.
Should I buy the cheapest brake pads available?
It's not recommended. Braking is a safety system. The cheapest pads often use lower-quality materials that can wear out very quickly, make excessive noise, and may not provide adequate stopping power in an emergency. Sticking with a reputable brand like Bosch, Akebono, or Raybestos is a wise investment in your safety.
Why are my original Volvo pads so dusty?
Original Equipment (OEM) pads for many European cars, including your S40, use a soft, organic compound. This material provides a great initial bite and feel but wears down quickly, creating a lot of fine, dark dust that sticks to your wheels. Switching to a quality ceramic aftermarket pad is the best way to solve this problem.
