Proper alignment of your Campagnolo H11 AFS Disc Rotors [paid link] is essential for ensuring optimal braking performance, safety, and longevity. Misalignment can lead to inconsistent braking, poor stopping power, and even damage to other components. In this guide, we’ll walk you through the steps of getting your H11 AFS disc rotors [paid link] perfectly aligned, ensuring a smooth, effective braking experience.

Understanding Rotor Alignment

Rotor alignment refers to the position of the rotor in relation to the brake caliper. A properly aligned rotor sits evenly in the caliper, with the brake pads making uniform contact across the rotor surface. Misalignment can cause issues such as noise, uneven pad wear, and subpar braking performance. When working with the H11 AFS Disc Rotors [paid link], it’s important to ensure that the rotor is mounted correctly and rotates smoothly without wobbling or rubbing against the brake pads.

Tools Required

Before starting the alignment process, gather the following tools:

• Torque Wrench [paid link]
• 5mm Allen Key
• Rotor Alignment Tool (optional)
• Tightening Tool for Rotor Bolts
• Brake Pad Spacers (optional)
• Cleaning Cloth
• Isopropyl Alcohol (for cleaning)

Step-by-Step Guide to Rotor Alignment

1. Remove the Wheel

The first step in rotor alignment is removing the wheel from the bike. Use the appropriate quick-release lever or thru-axle, depending on your bike’s setup, to safely remove the wheel. This will give you access to the rotor and caliper, allowing you to perform the necessary adjustments.

2. Inspect the Rotor for Damage

Before making any adjustments, take the time to inspect the rotor for any visible damage. Look for bent or warped areas, and check the rotor surface for any scoring or gouging. If the rotor is damaged beyond repair, it will need to be replaced. A bent rotor can often be straightened with a rotor truing tool, but if the damage is severe, a new rotor is necessary.

3. Clean the Rotor and Brake Pads

Next, clean both the rotor and the brake pads. Use isopropyl alcohol and a clean cloth to wipe down the rotor surface to remove any dirt, oil, or residue. Contaminants on the rotor or pads can lead to squealing and reduced braking performance. For the brake pads, inspect them for wear and replace them if they’re excessively worn down.

4. Check the Caliper Alignment

With the wheel removed, inspect the brake caliper’s alignment relative to the rotor. The caliper should be positioned so that the rotor runs through the center of the caliper, with the brake pads on each side. If the caliper is misaligned, it will need to be repositioned.

To check for misalignment, gently spin the rotor and observe any wobbling or rubbing of the pads against the rotor. If there’s noticeable rubbing, you’ll need to adjust the caliper position.

5. Adjust the Caliper

To realign the caliper, follow these steps:

• Loosen the caliper mounting bolts slightly using a 5mm Allen key.
• Center the caliper over the rotor.
• While holding the caliper in place, use the torque wrench [paid link] to carefully tighten the caliper mounting bolts, ensuring that the caliper remains centered over the rotor.
• Re-check the rotor’s spin and alignment to ensure no rubbing or wobbling occurs. Tighten the bolts to the manufacturer’s recommended torque specification once you’ve achieved proper alignment.

6. Align the Rotor Using a Truing Tool (Optional)

If your rotor is slightly bent or warped, you may need to straighten it. Use a rotor truing tool or a similar tool to gently adjust the rotor into its correct position. Apply light, even pressure on the rotor while rotating it to straighten out any high or low spots. Be cautious not to apply excessive force, as this can cause damage to the rotor.

7. Install the Wheel and Test the Brakes

Once the caliper is aligned and the rotor is trued, reinstall the wheel onto the bike. Before taking the bike out for a ride, test the brakes by squeezing the brake lever several times. The brake pads should engage smoothly with the rotor without any rubbing or noise. Check that the rotor spins freely and evenly, and that the braking performance is consistent.

8. Fine-Tuning

If you still notice any minor rubbing or squeaking after aligning the rotor, fine-tune the brake pad alignment. This can often be achieved by adjusting the pad contact using the caliper’s pad adjustment screws. Ensure the pads are evenly spaced from the rotor and making full contact when the brake is applied.

Common Issues with Rotor Alignment

While rotor alignment is a straightforward process, some common issues can arise:

1. Wobbly Rotor

If the rotor wobbles as it spins, it could be bent or misaligned. A rotor truing tool can help straighten it, but if the bending is excessive, replacement is necessary.

2. Brake Pads Rubbing on Rotor

Rubbing can occur if the caliper is misaligned or the rotor is not centered. Carefully readjust the caliper and check that the rotor is running true.

3. Rotor Contact with Caliper Mount

Sometimes, the rotor might come into contact with the caliper mount, especially if the mounting bolts are not tightened to the correct torque. Recheck the alignment and tightening torque to resolve this issue.

4. Noise After Alignment

If you hear persistent noise after alignment, it may be due to contamination on the rotor or pads. Clean both components thoroughly, and check the pads for any uneven wear that could cause them to make noise.

Maintaining Rotor Alignment

Once you’ve achieved proper rotor alignment, regular maintenance is essential to keep everything running smoothly:

• Regularly inspect your rotors for signs of wear, warping, or damage.
• Clean the rotors and pads after every ride, especially if you’ve been riding in wet or muddy conditions.
• Check the caliper alignment periodically to ensure it stays centered over the rotor.

By performing these basic maintenance tasks, you can extend the life of your Campagnolo H11 AFS Disc Rotors and ensure consistent braking performance on every ride.
