The Potenza 11s Disc Brake [paid link] system by Campagnolo delivers high-performance braking power, reliability, and modulation for road cyclists. Whether you are installing a new set, fine-tuning the setup, or maintaining them for long-term performance, proper knowledge of the system is crucial.
This guide will walk you through installation, adjustment, maintenance, and troubleshooting to ensure your Potenza 11s [paid link] disc brakes function flawlessly.
Tools Required
Before starting, gather the following tools:
- 5mm and 4mm Allen keys [paid link]
- Torque wrench [paid link] (with Nm settings for bolts)
- T25 Torx wrench [paid link]
- Campagnolo mineral oil [paid link] (for hydraulic systems)
- Bleed kit [paid link] (for hydraulic maintenance)
- Isopropyl alcohol and clean rags (for cleaning rotors and calipers)
- Disc brake pad spreader or plastic tire lever
Step-by-Step Installation of Potenza 11s Disc Brakes
1. Mounting the Brake Calipers
- Align the flat-mount or post-mount calipers to the frame and fork.
- Use the T25 Torx bolts and lightly tighten them to keep the caliper in place.
- If using a disc brake adapter, ensure it matches the rotor size and torque it correctly.
2. Installing the Rotors
- Attach the Campagnolo AFS (Axial Fixing System) rotors to the wheel hub.
- Use a T25 Torx wrench [paid link] to secure them, following the 6 Nm torque specification.
- Clean the rotor surface with isopropyl alcohol to remove any contaminants.
3. Connecting Hydraulic Hoses (If Applicable)
- Cut the hydraulic hose to the correct length using a hose cutter.
- Insert the olive and insert into the hose and attach it to the caliper.
- Tighten the banjo bolt to Campagnolo’s specified torque setting.
4. Bleeding the Hydraulic System
- Attach the bleed kit [paid link] to the caliper and lever.
- Use Campagnolo mineral oil [paid link] to remove air bubbles from the system.
- Follow the manufacturer’s bleed procedure to ensure consistent braking power.
Adjusting Potenza 11s Disc Brakes for Optimal Performance
1. Centering the Calipers
- Loosen the caliper bolts slightly and squeeze the brake lever to center the caliper on the rotor.
- While holding the brake lever, tighten the mounting bolts to 6-8 Nm.
- Check that the rotor spins freely without rubbing.
2. Adjusting Brake Pad Clearance
- If the pads rub against the rotor, use the barrel adjuster on the lever to fine-tune the gap.
- For hydraulic models, pump the brake lever to reset the pistons after installing new pads.
3. Checking Rotor Alignment
- Spin the wheel and inspect the rotor clearance between the brake pads.
- If the rotor is slightly warped, use a rotor truing tool to make small adjustments.
Routine Maintenance for Potenza 11s Disc Brakes
1. Cleaning the Brake System
- Use isopropyl alcohol and a clean rag to wipe down the rotors.
- Avoid using oil-based cleaners that could contaminate the pads.
2. Inspecting Brake Pads
- Remove the brake pads and check for wear. If the pad material is under 1.5mm, replace them.
- If pads are contaminated, lightly sand the surface or replace them if necessary.
3. Checking for Leaks (Hydraulic Models)
- Inspect the hose connections and caliper seals for oil leaks.
- If there is a leak, replace the olive and insert and re-bleed the system.
4. Rotor Wear and Replacement
- Measure the rotor thickness. If it is below 1.5mm, replace it.
- Check for deep grooves or warping, which can affect braking efficiency.
Troubleshooting Common Issues with Potenza 11s Disc Brakes
1. Brake Lever Feels Spongy
Cause: Air bubbles in the hydraulic system.
Solution: Bleed the brakes to remove trapped air.
2. Disc Brakes Are Squealing
Cause: Contaminated pads or rotors.
Solution: Clean the rotors with alcohol, and if necessary, replace the brake pads.
3. Braking Power Is Weak
Cause: Worn-out brake pads or misaligned caliper.
Solution: Replace pads if worn and ensure the caliper is centered correctly.
4. Brakes Are Rubbing
Cause: Caliper misalignment or bent rotor.
Solution: Re-align the caliper and true the rotor using a rotor truing tool.
Enhancing Performance and Longevity of Potenza 11s Disc Brakes
1. Upgrade to High-Performance Brake Pads
- Consider using organic pads for better modulation or sintered pads for durability in wet conditions.
2. Use the Correct Rotor Size
- If riding in the mountains, consider upgrading to 160mm rotors for increased stopping power.
3. Regularly Bleed the System
- Bleed the hydraulic system at least once a year to maintain consistent performance.
