What Is a Brake Upgrade Kit ?

A brake upgrade kit enhances or replaces key components of your motorcycle's braking system, commonly including:

• Aftermarket rotors for better heat dissipation
• Aftermarket Brembo Calipers with increased clamping force & modulation
• Higher quality brake pads with improved friction compounds
• Steel braided brake lines to reduce flex and improve braking capability

Together, these upgrades provide stronger, more predictable braking than stock components.

Key Benefits:

• Improved Stopping Power:  Upgraded brakes reduce stopping distance and increase braking authority -- especially noticeable at higher speeds.
• Better Modulation & Control:  Brembo calipers and pads allow smoother braking input, making it easier to control braking force 
• Fade Resistance:  Improved rotors and pads handle heat better, maintaining consistent braking during repeated or aggressive use
• Firmer lever feel -- Stainless steel braided brake lines eliminate the 'spongy' feel common with stock rubber lines
• Increased Rider Confidence:  Better brakes make riding safer and more enjoyable -- particularly on modified bikes
  
  

Installation & Safety Tips :

• Torque all hardware to manufacturer specifications
• Fully bleed the braking system after installation
• Properly bed in new brake pads to achieve full performance
• If unsure, professional installation by certified motorcycle mechanic is strongly recommended

Brakes are a Critical Safety System -- CORRECT Installation is Essential !

Common Questions
