The motorsport brake bias balance bar and cable are the most effective tools for fine-tuning your braking performance in motorsport. Whether you’re building a race, rally, or track-day car, getting your brake balance setup correct can dramatically improve stability, corner entry control, and overall lap consistency.

Why This Guide Matters. We’ve recently seen a few customers experience fitment issues, including stripped threads and minor fluid leaks, during installation.These problems are almost always caused by incorrect fitting, incorrect torque, using the wrong flare type, or over-tightening the M10 fittings. To help prevent this, we’ve created this detailed Upgrade Motorsport Bias Valve Correct Fittings & Torque Settings Installation Guide. In this guide we cover the correct fittings

Precision braking is the cornerstone of performance driving. Whether you are setting up a track car, developing a rally vehicle or fine-tuning a kit car for road and competition, understanding how hydraulic components interact will transform your driving experience. The master cylinder, brake bias valve, and hydraulic handbrake each play a critical role in how braking pressure, pedal feel and control are delivered to the wheels.

Lever and Screw Type Brake Bias Valve – Installation, Bleeding & Fitment Guide Upgrade your brake system with precision using the Lever Type or Screw Brake Bias Valve. Follow this guide to ensure safe, efficient installation and optimal performance.

his guide covers how to properly bench-bleed, install, and bleed the full brake system using your Upgrade billet flange master cylinder. Correct procedure is vital to ensure firm, consistent pedal feel and eliminate trapped air.

Before installing the master cylinder in your vehicle, you must bench bleed it. This process removes trapped air within the bore and ports that cannot be purged easily once installed. Skipping this step can leave air bubbles inside the master cylinder, leading to a soft pedal, uneven hydraulic pressure, and poor brake performance.

This guide provides the correct procedure for bleeding the brakes and tightening specifications for the Upgrade Motorsport Spherical Bearing Mount Master Cylinders (available in 0.625" and 0.7" bore sizes).Proper bleeding and torque application are critical for achieving consistent pedal feel and reliable braking performance.
