How to Properly Bed in Disc Brake Pads on New Wheelsets

Introduction: Why Bedding In Matters

When you install new disc brake pads or a new wheelset with fresh rotors, it's essential to bed them in—or “burn them in”—to ensure optimal braking performance. Bedding in allows the brake pad material to transfer a thin, even layer onto the rotor surface. This not only improves braking power and consistency but also minimizes squealing and extends the life of your pads and rotors.

Skipping this step can lead to poor modulation, inconsistent stopping, and glazing, which permanently reduces braking efficiency.

What Is Bedding In?

Bedding in is the process of gradually heating the brake pads and rotors through repeated, controlled braking, which:

Embeds pad material evenly onto the rotor surface

Conditions the rotor for consistent brake performance

Prevents uneven wear and brake noise

Enhances bite and modulation from your very first real ride

When Should You Bed In Your Disc Brakes?

When installing new brake pads

When switching to a new wheelset with different rotors

After a rotor cleaning or replacement

When swapping between pad compounds (e.g., resin to metallic)

Step-by-Step: How to Bed In Your Disc Brake Pads

Step 1: Choose a Safe, Flat Area

Find a traffic-free stretch of road, slight descent, or empty parking lot. This lets you repeat braking without distractions.

Step 2: Accelerate to Moderate Speed

Pedal up to about 20–25 km/h (12–15 mph). You want enough speed to apply braking force but not so fast that it’s unsafe.

Step 3: Firm but Controlled Braking

Use only one brake at a time (front or rear) to focus bedding on that rotor and pad set. Apply steady, firm pressure—not a full emergency stop—and reduce speed to walking pace.

Avoid skidding or locking up the wheels.

Step 4: Repeat the Process

Perform 10 to 15 cycles of accelerate → brake → roll.

Between each braking cycle, keep moving to allow pads and rotors to cool slightly.

You’ll start to feel the brakes getting stronger and more responsive. This means the bedding-in layer is forming correctly.

Step 5: Allow for Final Cooling

After completing the process, avoid aggressive braking for the next 5–10 minutes, allowing the brake surfaces to cool gradually and evenly.

Extra Tips for a Perfect Bed-In

Avoid contamination: Don’t touch rotors or pads with bare hands. Any grease or oil will ruin the process.

Don’t overheat: Overheating can glaze new pads. Stay within moderate speed and braking force.

Don’t bed in on wet surfaces: Moisture interferes with the transfer process.

What If I Skip This Step?

Poor initial braking power

Annoying brake squeal or vibration

Glazed pads or uneven rotor surfaces

Longer stopping distances

Conclusion

Bedding in your disc brake pads is a quick, crucial step to get the most out of your new wheelset. Whether you're racing, commuting, or gravel grinding, properly bedded-in brakes provide safer, quieter, and more responsive performance from day one.

When you invest in high-quality components—like carbon disc wheelsets—give them the right start with a proper bedding process. Your rotors, pads, and ride confidence will thank you.
