Galfer Rear Wave Brake Rotor

The Galfer Rear Wave Solid Brake Rotor is a high-performance, heat-dissipating rear brake disc engineered to replace solid OEM rear rotors that suffer from overheating, brake fade, and premature pad glazing. In off-road and motocross riding, the rear brake is subjected to continuous drag and heavy modulation in tight ruts and downhill descents. Factory round rotors trap heat and pad debris, causing the hydraulic brake fluid to boil and resulting in a spongy, useless rear brake pedal. Galfer's Wave rotor design completely transforms rear braking consistency.

Manufactured in Spain from high-carbon 420 stainless steel, the rotor is laser cut and double-disc ground to ensure absolute parallel flatness and zero runout. The patented Wave design introduces a non-concentric outer edge that constantly alters the contact radius across the brake pads. This wiping action continuously cleans pad surfaces, clears away mud and glaze, and allows air to penetrate the pad-rotor contact interface. The result is a rear brake with crisp pedal feel, progressive modulation that prevents accidental rear wheel lockup, and dramatically reduced operating temperatures during long downhill sections.

• Material: High-carbon 420 virgin stainless steel
• Design Pattern: Patented Galfer Wave contour with optimized thermal dissipation
• Surface Machining: Double-disc parallel ground to eliminate disc thickness variation
• Heat Treatment: Pre-heat treated to eliminate warping under extreme track temperatures
• Origin: Precision manufactured in Spain

### Step-by-Step Installation & Safety Protocols Installation is performed during a rear wheel removal. Remove the rear wheel and extract the four or six factory rear rotor bolts. Clean the hub mounting flange thoroughly of grit and old thread locker. Position the Galfer Wave rotor onto the hub, ensuring the laser-etched rotation arrow points in the direction of forward wheel rotation. Apply medium-strength thread locker to the rotor bolts and torque in a criss-cross pattern to factory specification (typically 14-16 Nm). Reinstall the rear wheel, aligning the rotor between the rear brake pads. Pump the rear brake pedal until firm before riding.

### Maintenance & Service Wear Limits Maintenance involves checking rotor thickness periodically with a vernier caliper and replacing the rotor if worn below the minimum thickness threshold stamped on the disc face (typically 3.5mm).
