The Campagnolo Ekar 13-speed disc brakes are a high-performance braking system designed for gravel and endurance road cycling. Built with lightweight materials and advanced hydraulic technology, they deliver excellent stopping power and modulation. However, proper installation, adjustment, and maintenance are crucial to ensure optimal performance and longevity.

This guide provides step-by-step instructions on how to install, adjust, and maintain your Ekar 13s [paid link] disc brakes while also covering troubleshooting tips for common issues.

Tools Required

To install and maintain the Ekar 13s [paid link] disc brakes, you will need the following tools:

  • 5 mm and 4 mm Allen wrenches [paid link] (for caliper and lever installation)
  • Torx T25 wrench (for rotor bolts)
  • Torque wrench [paid link] (to ensure proper tightening)
  • Cassette lockring tool [paid link] (for center-lock rotors)
  • Disc brake spacer (to prevent pad compression during installation)
  • DOT-compatible hydraulic brake fluid
  • Bleed kit [paid link] (specific to Campagnolo hydraulic systems)
  • Isopropyl alcohol and clean rags (for cleaning rotors and pads)

Step-by-Step Installation of Ekar 13s Disc Brakes

1. Installing the Brake Calipers

  1. Mount the calipers onto the frame and fork using the 5 mm Allen wrench [paid link].
  2. Ensure the calipers are centered over the rotor before tightening the bolts.
  3. Use a torque wrench [paid link] to tighten the mounting bolts to 6-8 Nm.
  4. Insert a disc brake spacer between the pads to prevent accidental compression.

2. Installing the Brake Rotors

For Center-Lock Rotors:

  1. Slide the rotor onto the hub with the arrow facing the correct direction.
  2. Use a cassette lockring tool [paid link] to tighten the rotor to 40 Nm.

For 6-Bolt Rotors:

  1. Align the rotor holes with the hub.
  2. Secure the Torx T25 bolts in a star pattern to ensure even tightening.
  3. Torque the bolts to 6-8 Nm to prevent warping.

3. Installing the Brake Levers and Connecting Hydraulic Hoses

  1. Position the brake levers on the handlebars and secure them with the 4 mm Allen wrench [paid link].
  2. Route the hydraulic hoses properly along the frame to avoid sharp bends.
  3. If cutting the hose, install a new olive and barb before reconnecting.
  4. Tighten the hose connections to 5-7 Nm using a torque wrench.

Adjusting Ekar 13s Disc Brakes for Optimal Performance

1. Centering the Brake Calipers

  1. Loosen the caliper mounting bolts slightly.
  2. Pull the brake lever firmly to align the caliper.
  3. While holding the lever, tighten the caliper bolts evenly to 6-8 Nm.
  4. Spin the wheel to check for brake rub—adjust if necessary.

2. Aligning Brake Pads Properly

  1. Remove the wheel and brake pads to inspect for uneven wear.
  2. Sand down glazed pads lightly with fine-grit sandpaper.
  3. Reinstall the pads and ensure they are seated evenly.
  4. Insert a spacer to reset the pistons before reinstalling the wheel.

3. Bleeding the Hydraulic System

Symptoms of Air in the System:

  • Spongy brake feel
  • Inconsistent braking power

How to Bleed the System:

  1. Attach the bleed kit [paid link] to the caliper and lever.
  2. Open the bleed valve and allow air bubbles to escape.
  3. Refill the system with Campagnolo-specific hydraulic fluid.
  4. Close the bleed valve and test the lever feel before riding.

Routine Maintenance of Ekar 13s Disc Brakes

1. Cleaning the Brake Rotors and Pads

  1. Use isopropyl alcohol to wipe down rotors and pads.
  2. Avoid using oily or greasy rags to prevent contamination.
  3. If braking feels weak, burnish the pads by braking hard on a descent.

2. Checking for Wear and Replacing Pads

  1. Inspect pads every 500-1000 km depending on riding conditions.
  2. Replace pads if the friction material is less than 1 mm thick.
  3. Always use genuine Campagnolo replacement pads for compatibility.

Troubleshooting Common Issues with Ekar 13s Disc Brakes

1. Brake Rub on Rotors

  • Loosen and realign the calipers.
  • Check for warped rotors and replace if necessary.
  • Ensure rotor bolts are tightened evenly.

2. Spongy Brake Feel

  • Bleed the hydraulic system to remove air bubbles.
  • Check for leaks at hose fittings and tighten if needed.

3. Noisy Braking or Squealing

  • Clean pads and rotors thoroughly.
  • Ensure proper pad alignment and burnish new pads before long rides.

Conclusion

The Campagnolo Ekar 13s disc brakes provide superior braking power and control, but proper installation and maintenance are essential for their longevity. By following this guide, you can ensure optimal performance and avoid common braking issues.
