The Shimano BR-5700 [paid link] caliper brakes, part of the trusted 105 series, are known for their smooth modulation, consistent power delivery, and performance-oriented design. Ensuring these brakes remain in top condition requires routine maintenance that not only preserves stopping efficiency but also extends the lifespan of the braking system. Whether you’re prepping for a race, tackling daily commutes, or enjoying weekend rides, optimal brake condition is non-negotiable for safety and control.

This guide will walk you through everything needed to keep your BR-5700 [paid link] calipers responsive, smooth, and noise-free, using recommended best practices for adjustment, cleaning, inspection, and component replacement.

Understanding the Shimano BR-5700 Brake Design

The BR-5700 [paid link] is a dual-pivot caliper brake, a hallmark of Shimano’s performance engineering. It provides improved leverage and balanced braking force on both sides of the rim, reducing flex and improving braking control. With its reach of 49 mm, it accommodates most modern road frames and forks. The cartridge-style brake pads make replacements convenient and secure.

Its compatibility with standard Shimano STI levers ensures seamless integration into most road bike drivetrains using 10-speed systems.

Maintenance Frequency and Inspection Schedule

Routine checks and timely intervention prevent degradation of braking power. Here’s a recommended maintenance cycle:

  • Every 2 weeks or 150 km: Inspect pad wear and brake function.
  • Every 3 months: Clean caliper arms, pivot bolts, and inspect cable condition.
  • Every 6 months: Replace worn pads and lubricate pivots.
  • Annually: Replace cables and housing, overhaul caliper arms if needed.

Sticking to this schedule helps detect early signs of performance issues like uneven pad wear or stiff pivot movement.

Tools Required

  • 5 mm hex wrench
  • Cable cutters
  • Torque wrench [paid link] (with 5 Nm setting)
  • Isopropyl alcohol and clean cloths
  • Brake pad wear indicator or caliper gauge
  • Shimano-compatible cartridge pads (R55C4 or equivalent)
  • Cable lubricant or PTFE spray
  • Needle-nose pliers

Cleaning and Lubrication Protocol

Clean brakes function better and wear more slowly. Follow this simple process for effective cleaning:

  1. Wipe the calipers and pads with a lint-free cloth and isopropyl alcohol. This removes road grime and residue that can cause noise or inconsistent braking.
  2. Inspect the braking surface of the rim to remove embedded debris, especially if you ride in wet conditions.
  3. Clean pivot bolts and springs using a small brush, then apply a drop of lubricant to each pivot. Avoid contaminating the brake pads during this process.

For lubrication:

  • Use minimal, targeted lubrication to avoid attracting dirt.
  • Do not lubricate the braking surface or pad contact points.

Brake Pad Maintenance and Replacement

The BR-5700 uses cartridge pads with replaceable inserts. This makes maintenance cost-effective and simple. Key points to check:

  • Wear Indicators: Replace pads when grooves disappear or wear indicators are no longer visible.
  • Alignment: Pads must strike the rim squarely without touching the tire or dropping below the braking surface.
  • Toe-In Adjustment: Angle the front of the pad slightly inward to reduce squeal and improve modulation.

To replace the pad:

  • Slide out the worn insert using needle-nose pliers.
  • Insert the new pad, ensuring it seats completely in the carrier.
  • Secure the fixing bolt without overtightening.

Cable Condition and Tension Adjustment

Smooth cable operation is critical for responsive braking. Inspect for:

  • Fraying or kinking at lever and caliper ends
  • Rust or corrosion on exposed cable
  • Increased lever pull before engagement

Adjust cable tension using the barrel adjuster:

  • Increase tension to reduce lever travel
  • Decrease if brakes feel too tight or drag

For severely stretched or damaged cables, replacement is necessary. Lubricate new cables before routing them through the housing for smoother operation.

Centering the BR-5700 Brake Calipers

Brake calipers must apply even force on both sides of the rim. If one pad contacts before the other:

  • Use the centering bolt (5 mm hex) to adjust caliper position.
  • Turn clockwise or counter-clockwise until both pads engage the rim at the same time.

Calipers should return to center after release. If not, check pivot spring tension or for debris inside the return spring mechanism.

Diagnosing Common Performance Issues

Soft Braking Feel:
This may result from excessive cable stretch, pad glazing, or rim contamination. Re-tension cables, clean rims and pads, or replace cables.

Brake Squeal:
Usually caused by misaligned pads or dirty braking surfaces. Realign pads with toe-in and clean both contact surfaces thoroughly.

Pad Drag:
Occurs if pads stay too close to the rim. Adjust the barrel or re-center the caliper.

Stiff Brake Arms:
Dry or corroded pivots may cause slow return. Apply lubricant to pivot bolts and check spring tension.

Long-Term Optimization Tips

To maintain peak performance year-round:

  • Always store your bike in a dry location.
  • Check pad wear before every major ride.
  • Replace brake cables yearly, even if not visibly damaged.
  • Upgrade to higher compound pads (e.g., Shimano R55C4-A for all-weather riding).
  • Periodically remove the caliper for a deep clean and pivot inspection.

Routine care doesn’t just preserve stopping power—it enhances ride quality and boosts rider confidence.

FAQs About Shimano BR-5700 Brake Maintenance

1. How often should I replace the pads on my BR-5700 brakes?
Replace pads when the wear indicators vanish or braking becomes inconsistent—typically every 2,000–4,000 km, depending on usage.

2. What’s the correct torque for mounting BR-5700 calipers?
The mounting bolt should be tightened to 6–8 Nm using a calibrated torque wrench [paid link].

3. Can I use carbon-specific pads with BR-5700 brakes?
Yes, if you’re running carbon rims. Always match the pad type to your rim material to prevent damage or reduced performance.

4. Are BR-5700 calipers compatible with modern Shimano levers?
They are designed for 10-speed Shimano STI levers but may not perform optimally with newer 11-speed levers due to leverage differences.

5. Why are my brakes squealing after cleaning?
Possible causes include pad contamination, poor toe-in alignment, or uncleaned rims. Reclean, readjust, and ensure pads are correctly set.

6. Can I install wider tires with the BR-5700 brake set?
They allow up to 28mm tires on many frames, but clearance depends on your frame/fork geometry and fender setup.

Conclusion

Proper maintenance of your Shimano BR-5700 brakes is not just about ensuring safety—it’s about optimizing every ride for smooth, responsive control. By following a consistent cleaning schedule, inspecting key components, and making minor adjustments when needed, you can preserve braking efficiency and avoid costly repairs. These brakes, when correctly maintained, deliver the performance Shimano is known for—ride after ride.
