Can You Upgrade Your Shimano BR-5700 Brakes? Compatibility and Best Practices

Posted on

The Shimano BR-5700 [paid link] is a dual-pivot road brake caliper originally introduced as part of the 105 5700 series. Known for its reliable stopping power and mid-tier affordability, the BR-5700 [paid link] remains a popular choice among recreational riders and amateur racers. However, with the evolving standards in road bike components, many cyclists wonder whether it’s possible—or even advisable—to upgrade these brakes. This guide provides a deep dive into potential upgrade paths, compatibility factors, and how to ensure optimal performance when making changes to your BR-5700 [paid link] setup.

Understanding the Shimano BR-5700 Brake Design

Before discussing upgrade options, it’s important to understand the mechanical design and limitations of the BR-5700. This model uses a traditional dual-pivot side-pull mechanism and is designed for use with road caliper brake frames with a standard reach (39–49 mm). It’s mechanically actuated via brake cables, not hydraulic systems, and requires rim brake-compatible wheels.

It features:

  • Aluminum construction with anodized finish
  • Adjustable spring tension
  • Cartridge-style brake shoes
  • Quick-release mechanism for wheel removal

While robust and straightforward, it lacks the more refined modulation and clearance of more modern or high-end caliper brakes.

Upgrade Compatibility: What Works and What Fails

Upgrading the BR-5700 brakes involves two key paths: replacing the calipers themselves or enhancing performance with better components. Here’s a breakdown of compatibility considerations:

Caliper Replacement with Newer Models

Shimano’s current lineup includes the 5800, R7000, and Dura-Ace series (9000, 9100). The most seamless upgrade would be to the Shimano BR-5800 [paid link] or R7000 series.

  • Compatible Upgrades: These calipers retain the dual-pivot architecture and cable-actuation format. They also use the same mounting bolt standards and fit traditional road frames.
  • Incompatible or Risky Upgrades: Direct-mount calipers or hydraulic disc brakes are not backward-compatible without a complete frame and fork replacement. Likewise, Shimano’s latest Dura-Ace models may not provide noticeable benefits on frames with limited clearance or older rim designs.

Brake Lever Compatibility

Upgrading calipers is only effective if your brake levers provide sufficient cable pull and modulation. The BR-5700 pairs best with Shimano STI levers from the same 10-speed generation (5600, 5700). Newer 11-speed levers (5800, R7000) are compatible, but mixing brands (e.g., SRAM or Campagnolo) may yield subpar performance due to differing cable pull ratios.

Performance Enhancements Without Full Replacement

If you’re not ready to fully replace your BR-5700 brakes, several performance-focused upgrades are available:

Brake Pad Upgrades

One of the most cost-effective upgrades is replacing stock pads with high-performance options. Look for:

  • SwissStop Flash Pro or Kool Stop Dura pads for improved wet/dry stopping power
  • Carbon-specific pads if you’re using carbon rim wheels

Better pads significantly enhance braking performance, especially in poor weather.

Brake Cable and Housing

Switching to a low-friction cable set such as Shimano SP41 or Jagwire Pro series can offer smoother lever feel and stronger return spring action. Pairing this with compressionless housing further improves power transfer.

Tuning and Alignment

Precise alignment of the brake shoes to the rim, proper centering, and equal cable tension on both calipers dramatically impact brake performance. In many cases, a careful tune-up offers a “like-new” feel even on older calipers.

Common Upgrade Pitfalls to Avoid

Many riders jump into upgrades without assessing the compatibility of other bike components. Key mistakes include:

  • Mismatched lever/cable pull ratios: Leads to spongy or over-sensitive braking
  • Exceeding frame/fork clearance: Some newer calipers are wider and may rub on tires or fenders
  • Assuming disc brakes are a drop-in solution: Rim brake frames cannot accommodate discs without structural modification

Always confirm frame dimensions and existing component compatibility before committing to any upgrade.

When to Fully Replace the BR-5700

Consider replacing your BR-5700 calipers when:

  • You’ve already upgraded pads, cables, and levers without noticeable improvement
  • Your rims are wider and require better caliper clearance
  • You’ve upgraded to 11-speed drivetrains and want fully matched 105 or Ultegra groupsets

In these scenarios, moving to a newer Shimano 105 (R7000) or Ultegra (R8000) brake set delivers smoother action, better modulation, and lighter weight—all without sacrificing compatibility.

Best Practices for a Successful BR-5700 Brake Upgrade

To ensure a smooth upgrade process, follow these best practices:

  • Check frame and fork compatibility with new brake models, especially for reach and tire clearance
  • Match lever and caliper brands to maintain consistent cable pull behavior
  • Use torque specifications from Shimano’s official documents during installation
  • Test braking under load before taking the bike out for a full ride

A measured and informed approach will yield safer, more responsive braking, often at a relatively low cost.

FAQs About Upgrading Shimano BR-5700 Brakes

Can I upgrade my BR-5700 brakes to disc brakes?
No, unless your frame and fork are specifically designed for disc brakes. This would require a new bike or significant structural changes.

Are Shimano R7000 calipers compatible with BR-5700 levers?
Yes, although they are designed for 11-speed systems, they work with 10-speed levers with only minimal differences in feel.

Will upgraded brake pads really make a difference?
Yes. High-performance pads significantly improve braking power, especially in wet or steep conditions.

Is it worth upgrading the entire brake system or just tuning what I have?
For most recreational riders, upgrading pads, cables, and alignment provides noticeable gains. Full replacement is only essential if your current setup underperforms or is damaged.

Do I need professional help to install upgraded calipers?
Not necessarily. With proper tools and a torque wrench [paid link], most cyclists can replace calipers at home. However, if unsure, professional installation ensures optimal results.

Can I use carbon-specific brake pads with aluminum rims?
No. Carbon pads are too hard for aluminum rims and may damage them. Always match pads to rim material.

By following this guide, you can confidently determine whether upgrading your Shimano BR-5700 brakes is the right move—and if so, which components and best practices will maximize your investment. Thoughtful upgrades can breathe new life into older brake systems and enhance safety and ride quality without a full drivetrain overhaul.
