The Super Record 12s[paid link] Disc Brakes from Campagnolo are among the most advanced hydraulic disc braking systems available for road bikes. Designed for precision braking, superior modulation, and top-tier performance, these brakes require careful installation, precise adjustment, and routine maintenance to ensure optimal functionality.

This guide provides a step-by-step breakdown of how to install, adjust, and maintain your Super Record 12s[paid link] Disc Brakes for maximum performance and longevity.

Tools Required

  • 5mm and 4mm Allen keys
  • Torx T25 wrench
  • Torque wrench[paid link]
  • Bleed kit (specific to Campagnolo hydraulic systems)
  • DOT 5.1 or Campagnolo-recommended mineral oil[paid link]
  • Disc brake cleaner
  • Isopropyl alcohol
  • Clean lint-free cloth
  • Rotor truing tool

Step 1: Installing the Super Record 12s Disc Brakes

1.1 Mounting the Brake Calipers

  1. Align the caliper over the mounting holes on the frame or fork.
  2. Use a Torx T25 wrench to tighten the caliper bolts loosely.
  3. Check for correct caliper alignment with the rotor by centering it before final tightening.
  4. Torque the bolts to 6-8 Nm, as recommended by Campagnolo.

1.2 Installing the Brake Rotors

  1. If using Centerlock rotors, slide the rotor onto the hub and secure it with the lockring. Use a lockring tool[paid link] to tighten it to 40 Nm.
  2. If using 6-bolt rotors, secure them with a Torx T25 wrench, tightening them in a star pattern to 6 Nm to ensure even tension.
  3. Clean the rotors with isopropyl alcohol before use to remove contaminants.

1.3 Connecting the Hydraulic Hoses

  1. If pre-installed, check for any leaks or kinks in the hose.
  2. If installing new hoses, cut the hose to the correct length and insert the Campagnolo olive and insert.
  3. Secure the hose into the brake lever and torque the connection bolt to 5-6 Nm.

Step 2: Adjusting the Super Record 12s Disc Brakes

2.1 Centering the Brake Calipers

  1. Loosen the caliper bolts slightly while keeping the caliper aligned.
  2. Pull the brake lever firmly to center the caliper over the rotor.
  3. While holding the lever, tighten the caliper bolts evenly to 6-8 Nm.
  4. Spin the wheel to check for rotor rubbing and make micro-adjustments if necessary.

2.2 Adjusting Lever Reach

The Super Record 12s hydraulic levers feature an adjustable reach mechanism:

  1. Locate the reach adjust screw on the inside of the brake lever body.
  2. Use a 2.5mm Allen key to adjust the reach, bringing the lever closer or further away as needed.
  3. Test the lever feel and adjust further if necessary.

Step 3: Bleeding the Super Record 12s Disc Brakes

3.1 When to Bleed Your Brakes

  • If the brake lever feels spongy or inconsistent.
  • If you’ve cut the hydraulic hoses during installation.
  • If the brakes lack power or have been contaminated with air bubbles.

3.2 How to Bleed the Brakes

  1. Attach the bleed kit syringe to the caliper bleed port.
  2. Open the brake lever bleed port and attach a second syringe filled with Campagnolo hydraulic fluid.
  3. Slowly push the fluid through the system, ensuring no air bubbles remain.
  4. Close both bleed ports and wipe off excess fluid.
  5. Pump the brake lever to ensure a firm braking feel.

Step 4: Maintaining the Super Record 12s Disc Brakes

4.1 Cleaning the Rotors

  1. Use isopropyl alcohol and a lint-free cloth to wipe down the rotor surface.
  2. Avoid touching the rotor with bare hands to prevent contamination.
  3. Check for warping and use a rotor truing tool if necessary.

4.2 Inspecting Brake Pads

  1. Remove the wheel and inspect pad thickness. Replace pads if they are worn below 1mm.
  2. Clean the pads with fine sandpaper if they appear glazed.
  3. Reinstall the pads and ensure proper alignment.

Step 5: Troubleshooting Common Super Record 12s Disc Brake Issues

5.1 Brake Noise or Squealing

  • Clean the rotors and pads with isopropyl alcohol.
  • Check for pad contamination and replace if necessary.
  • Ensure correct pad and rotor alignment.

5.2 Soft or Spongy Brakes

  • Check for air in the system and perform a brake bleed.
  • Inspect the hoses for leaks or kinks.
  • Ensure the brake lever is properly adjusted.

Conclusion

The Super Record 12s Disc Brakes provide exceptional stopping power and control when properly installed, adjusted, and maintained. Regular cleaning, bleeding, and pad replacement will ensure that your braking system remains in peak condition for years to come. By following this guide, you can achieve optimal performance and ride with confidence.
