Essential Bedding-in Process for MTB Riders: Maximizing Braking Performance

Even the most advanced brake pad will not deliver its full potential without a proper bedding-in process. This crucial step allows the pad and rotor to work together as a unified braking surface, ensuring consistent, powerful, and predictable stopping performance.

Why Bedding-in Matters?

When a new brake pad is installed, its surface is fresh, and the rotor’s surface may contain microscopic imperfections or residues. Bedding-in creates a uniform transfer layer — a thin film of pad material evenly deposited on the rotor.

This layer:

• Improves friction consistency for better modulation.

• Reduces noise and vibration.

• Enhances heat management and reduces the risk of glazing.

• Extends pad and rotor lifespan.

Skipping or rushing this process can lead to:

• Inconsistent braking feel.

• Reduced stopping power.

• Premature pad or rotor wear.

Preparation Before Bedding-in

1. Clean the Brake System

   • Thoroughly clean both the rotor and caliper to remove dust, dirt, and oils.

   • If switching from a different pad compound, lightly scuff the rotor surface with fine sandpaper (120–240 grit) in circular motions to remove the old transfer layer.

   • Clean the rotor using brake cleaner or isopropyl alcohol to ensure it is free from contaminants.

   • Do not use any cleaners that contain oil or similar sprays, as they can reduce the braking power of your pads.

2. Check Caliper Alignment and Piston Position
   

   • Retract pistons fully before installing new pads.

   • Confirm all pistons move evenly when the lever is pressed.

   • Align the caliper so pads sit evenly around the rotor without constant contact.

MTB Bedding-in Process

1. Choose a Safe Location

   • Ideally, a gentle downhill section of around 100 m / 330 ft, free of obstacles.

2. Initial Heating Phase

   • Accelerate to a moderate speed and apply light-to-moderate brake pressure for 2–3 seconds.

   • Release the brake before coming to a complete stop.

   • Repeat 10–20 times, allowing gradual heat build-up.

3. Cooling Phase

   • Ride without heavy braking for several minutes to allow gradual cooling.

Key Notes:

• Avoid holding the brake lever fully after heavy braking — this can cause uneven hot spots.

• Avoid repeated hard stops without cooling, which may warp the rotor.

Special Considerations for Top Brake Pads

• Material Characteristics: Our compounds are engineered for durability and high thermal stability. Bedding-in may take slightly longer than with softer compounds, but this ensures stable performance under extreme MTB conditions.

• Rotor Compatibility: Always ensure your rotor is within the manufacturer’s thickness specification and free from excessive wear or warping before starting the process.

• Maintenance: For maximum performance, keep the rotor clean and free from oil-based or penetrating substances that can permanently affect friction surfaces.

When to Check the Rotor and Caliper

If braking performance remains low after a correct bedding-in process, inspect the rotor for:

• Overheating signs (blue or discolored areas).

• Warping or uneven thickness.

• Surface contamination.

Also, ensure the caliper is functioning properly and pistons are moving freely. (Learn more about the signs that indicate MTB brake pads are overheating.)
