R3 Brake Upgrade

Enhancing Braking Performance: Upgrading the Brake System on a Yamaha R3

When it comes to motorcycles, safety should always be a top priority. One of the most critical components contributing to a rider’s safety is the braking system. While the stock brake system on the Yamaha R3 is adequate for everyday riding, upgrading it with high-performance components can significantly enhance braking performance and overall control. In this blog post, we’ll explore the benefits of upgrading the brake system on a Yamaha R3, specifically through the installation of new HEL braided brake lines, a Brembo P4 caliper, a Brembo RCS15 master cylinder, and disabling the ABS system.

Braided Brake Lines: A Step Towards Efficiency and Consistency

Replacing the stock rubber brake lines with braided brake lines from Hel is an excellent first step towards improving braking performance. Braided lines offer superior strength and rigidity, reducing the amount of flex during braking. This translates into a more responsive and consistent braking feel, enhancing control and feedback.

Brembo P4 Caliper: Unleashing Optimal Stopping Power

The addition of a Brembo P4 caliper takes braking performance to a whole new level. Brembo is renowned for manufacturing high-quality braking components used in top-tier motorcycles and racing machines. The P4 caliper offers superior clamping force, ensuring excellent stopping power and enhanced modulation. With this upgrade, you can expect increased confidence when diving into corners and the ability to bring the Yamaha R3 to a halt swiftly and effortlessly. The P4 caliper is a monoblock caliper, meaning it is machined from a single block of aluminum alloy, providing superior rigidity and strength. This design helps reduce flex and provides more precise and consistent braking performance. Keep in mind that in order to mount the P4 caliper on the R3, you will need a special mounting bracket. In this video, I am using the Tyga unit but Spears Racing also offers a similar option. Both products are top notch!

Brembo RCS15 Master Cylinder: Precision Control at Your Fingertips

The Brembo RCS15 master cylinder is a masterstroke in precision control. With its adjustable lever ratio, you can tailor the braking feel to your liking. The RCS15 offers two settings, allowing you to switch between a more progressive feel for everyday riding and a more aggressive setup for spirited sessions on the track. This versatility ensures optimal control and enables you to extract the full potential of the upgraded brake system.

Disabling the ABS System: Personalizing the Braking Experience

While ABS (Anti-lock Braking System) undoubtedly enhances safety by preventing wheel lock-up, some riders (me included) prefer to have direct control over the braking process. Disabling the ABS system allows you to tailor the braking performance to your liking, making it ideal for experienced riders who are comfortable with manual modulation and seeking a more engaging riding experience.

Motul Brake Fluid: Designed to Resist High Temperatures

My go-to brake fluid is the Motul RBF660 for the racetrack and I normally use the RBF600 for road riding. Motul RBF660 is a high-performance brake fluid designed for extreme racing conditions. It has a higher boiling point compared to RBF600, making it more resistant to brake fade under intense heat generated during aggressive braking. For regular street riding or moderate performance requirements, the Motul RBF600 brake fluid should provide ample performance and safety.


Upgrading the brake system on your Yamaha R3, through the installation of braided brake lines, a Brembo P4 caliper, a Brembo RCS15 master cylinder, and disabling the ABS system, offers several benefits that significantly enhance your riding experience. The combination of these components improves braking efficiency, provides superior stopping power, and gives you precise control over your motorcycle’s braking performance.
