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.
