The Campagnolo Super Record EPS 12s [paid link] Disc Brakes are a top-tier choice for road cyclists who demand precision, reliability, and powerful braking. Designed for high-performance riding, these brakes deliver smooth modulation and exceptional stopping power. However, proper installation and maintenance are crucial to ensure peak performance.

In this guide, we will walk you through the complete process of installing, adjusting, and maintaining your Super Record EPS 12s [paid link] Disc Brakes, along with troubleshooting tips to fix common issues.

Tools Required

Before you begin, gather the following tools:

  • 5mm and 4mm Allen keys [paid link]
  • Torx T25 wrench
  • Torque wrench [paid link]
  • Brake fluid (Campagnolo mineral oil [paid link])
  • Syringe and bleed kit [paid link]
  • Isopropyl alcohol and clean rags
  • Rubber gloves
  • Disc brake spacer

Step-by-Step Installation Guide

1. Mounting the Brake Calipers

  1. Start by attaching the front and rear calipers to the frame and fork using a Torx T25 wrench.
  2. Align the calipers loosely so they can be adjusted later.
  3. Use a torque wrench [paid link] to tighten the bolts to Campagnolo’s recommended torque specifications (6-8 Nm).

2. Installing the Brake Rotors

  1. Place the Super Record 160mm or 140mm rotors onto the wheel hub.
  2. Secure the rotors using the lockring and tighten them with a cassette lockring tool [paid link].
  3. Spin the wheel to check for rotor alignment and clearance.

3. Connecting the Hydraulic Hoses

  1. Insert the hydraulic hose into the caliper and secure it with the compression fitting.
  2. Route the hose cleanly along the frame to the brake lever.
  3. Trim excess hose length with a hydraulic hose cutter and install the Campagnolo-specific olive and insert.
  4. Tighten the hose connections to prevent leaks.

4. Bleeding the Brake System

  1. Remove the brake reservoir cap on the levers.
  2. Attach a syringe with fresh Campagnolo mineral oil [paid link] to the bleed port.
  3. Slowly push fluid through the system while tapping the calipers to release air bubbles.
  4. Once no air bubbles appear, close the bleed port and reinstall the reservoir cap.
  5. Clean up any excess fluid with isopropyl alcohol.

Adjusting the Super Record EPS 12s Disc Brakes

1. Aligning the Brake Calipers

  • Loosen the caliper mounting bolts slightly.
  • Squeeze the brake lever firmly to center the caliper on the rotor.
  • While holding the brake lever, tighten the mounting bolts gradually.
  • Spin the wheel to check for rotor rubbing. If rubbing occurs, make minor adjustments by shifting the caliper slightly.

2. Adjusting Lever Reach and Modulation

  • The Super Record EPS 12s levers have an adjustable reach screw near the pivot point.
  • Use a 2.5mm Allen key to adjust the lever reach for optimal hand comfort.
  • For modulation tuning, fine-tune the lever free stroke by adjusting the inline barrel adjuster.

Maintenance Guide for Long-Term Performance

1. Cleaning the Brake System

  • Wipe the rotors with isopropyl alcohol after every ride to remove contaminants.
  • Avoid touching the brake rotors with bare hands, as oils can reduce braking power.
  • Use a clean, dry rag to wipe down the calipers and brake levers.

2. Checking Brake Pad Wear

  • Remove the wheel and inspect the brake pads.
  • If pad thickness is below 1.5mm, replace them immediately.
  • Install new Campagnolo pads by removing the pad retaining bolt, swapping the old pads, and reinstalling the bolt securely.

3. Replacing Brake Fluid

  • Replace the brake fluid every 12-18 months to prevent contamination.
  • Use only Campagnolo-approved mineral oil to maintain system integrity.

Troubleshooting Common Issues

1. Brake Lever Feels Spongy

  • Air bubbles in the hydraulic system may be causing poor brake response.
  • Perform a thorough bleed using fresh Campagnolo mineral oil.

2. Brakes Squeal or Make Noise

  • Contaminated rotors or pads can cause noise.
  • Clean rotors with isopropyl alcohol and sand brake pads lightly with fine-grit sandpaper.

3. Brake Pads Rub Against the Rotor

  • Check for proper caliper alignment and adjust if necessary.
  • Ensure the wheel is seated correctly in the dropouts.

4. Braking Power Feels Weak

  • Worn-out pads or glazed rotors may be the issue.
  • Replace brake pads and lightly sand the rotor surface.
