Maintaining the Ekar AFS (Axial Fixing System) disc brakes is essential for ensuring optimal braking performance, safety, and longevity. These disc brakes, developed by Campagnolo for gravel and road cycling, require regular maintenance to keep their efficiency intact. In this article, we will cover the necessary steps for maintaining your Ekar AFS disc brakes, ensuring they perform at their best over time.

Regular Cleaning of Your Ekar AFS Disc Brakes

Keeping your Ekar AFS disc brakes clean is the first and foremost maintenance task. Dirt, mud, and road grime can affect the braking performance and lead to uneven wear on the rotor and brake pads.

Steps to Clean Your Ekar AFS Disc Brakes:

  • Step 1: Use a soft cloth or brush to remove large debris from the rotors and calipers. Avoid using harsh brushes that can damage the brake pads or rotors.
  • Step 2: Spray a bike-specific cleaner or rubbing alcohol on the rotors to remove oils, grime, or residue. Apply it gently to avoid getting the cleaner on the brake pads.
  • Step 3: Use the cloth to wipe down the rotors, making sure no liquid cleaner is left behind.
  • Step 4: Check the calipers for any dirt accumulation and use a soft brush to clean them.

It’s important to clean your brakes after every ride, especially in wet or muddy conditions. Regular cleaning ensures that debris doesn’t get trapped between the rotor and brake pads, preventing uneven wear and poor braking performance.

Inspecting Your Ekar AFS Disc Brakes

Routine inspections are crucial to ensure that your Ekar AFS disc brakes are functioning correctly. This involves checking both the brake pads and the rotors for wear, alignment, and proper functioning.

Brake Pads:

  • Inspect the brake pads for wear. Campagnolo Ekar AFS brake pads should have a minimum thickness of 1mm. If they are worn beyond this point, it’s time for a replacement.
  • Check for uneven pad wear. This could indicate misalignment of the brake calipers or issues with the rotor.
  • Look for any glazing on the pads, which can occur if the brake pads have overheated. If glazed, the pads should be replaced.

Rotors:

  • Check for any warping, cracks, or excessive wear on the Ekar AFS rotors. The rotor thickness should be checked regularly using a caliper. Campagnolo recommends replacing rotors if the thickness has dropped below the minimum specification (1.5mm).
  • Ensure the rotors are free of any oil or dirt, as this can cause squealing or reduced braking power.

Adjusting Your Ekar AFS Disc Brakes

Adjustments to the brake pads and rotor alignment are necessary to maintain the precision braking that Ekar AFS disc brakes are known for. Proper pad alignment ensures maximum contact with the rotor, providing consistent braking force.

Pad Alignment:

  • To adjust pad alignment, first, check if the caliper is mounted securely to the frame. If not, tighten it using the correct torque specifications as provided by Campagnolo.
  • If the pads are misaligned, you can adjust the position by loosening the caliper bolts slightly and repositioning it. Once in place, re-tighten the bolts and check the alignment again.

Rotor Alignment:

  • Rotor alignment is key to achieving smooth braking. Check the rotor to ensure it is centered between the brake pads. If the rotor is misaligned, use a rotor truing tool to gently straighten it. Campagnolo recommends only minor adjustments to avoid damaging the rotor.
  • If the rotor is excessively warped, it might need to be replaced.

Bleeding the Brakes

Hydraulic disc brakes like the Ekar AFS are self-adjusting, but over time, air can enter the brake lines, causing a spongy feel when braking. Bleeding the brakes is a necessary maintenance task to ensure optimal braking performance.

Steps to Bleed Ekar AFS Brakes:

  • Step 1: Set up a clean workspace with the necessary tools: a brake bleed kit [paid link], syringe, and fresh brake fluid.
  • Step 2: Remove the wheel from the bike to access the brake calipers.
  • Step 3: Attach the syringe filled with brake fluid to the caliper’s bleed port.
  • Step 4: Open the bleed valve and allow fluid to flow through the system until all the air bubbles are expelled. Close the valve when the fluid is free of bubbles.
  • Step 5: Reassemble the calipers and check the brake lever for responsiveness. Test the brakes on the bike before riding.

Regular bleeding (every 6-12 months, depending on usage) will ensure that your Ekar AFS brakes remain responsive and do not suffer from a spongy lever feel.

Maintaining Optimal Braking Power with Proper Rotor and Pad Selection

To maintain maximum stopping power, it’s essential to use the correct rotors and pads for your riding style. Campagnolo Ekar AFS rotors are designed for gravel and road use, offering durability and high performance.

  • Rotor Selection: Make sure to use Campagnolo Ekar AFS rotors, as they are specifically designed for this brake system. Aftermarket rotors may not provide the same level [paid link] of performance or compatibility.
  • Pad Selection: Use the recommended brake pads for the Ekar AFS system. Campagnolo offers several pad options, including resin and metallic variants. Resin pads are quieter but wear out quicker, while metallic pads offer better performance in wet conditions but tend to be noisier.

Storing Your Bike Properly

Proper storage is a key factor in maintaining your Ekar AFS disc brakes. Avoid leaving the bike in direct sunlight or in areas where extreme temperatures are common, as this can degrade the brake fluid and cause premature wear on the pads and rotors.

When storing your bike for an extended period, it’s advisable to clean the brake system thoroughly and store it in a dry, cool place. Avoid leaving your bike in wet or humid conditions, as moisture can cause rusting or other damage to the brake components.

Conclusion

Maintaining your Ekar AFS disc brakes is crucial for ensuring safety and performance on your rides. By regularly cleaning, inspecting, and adjusting your brakes, you can maximize their lifespan and keep them operating at peak efficiency. Always follow Campagnolo’s maintenance guidelines for optimal performance and consider replacing worn components before they affect your braking power. With proper care, your Ekar AFS disc brakes will continue to provide excellent stopping power, no matter where your cycling adventures take you.
