TC Bros. 12.6" Oversized Front Floating Brake Rotor for 2000-Up Harley-Davidson Wheels

TC Bros. 12.6" Oversized Front Floating Brake Rotor for 2000-Up Harley-Davidson Wheels

If you're re-engineering your brake system for maximum stopping ability, an oversized disc is a natural starting point.

• Larger-than-stock rotor for custom brake applications; this is the missing link between sport-derived calipers and Harley-Davidson wheels
• Choice of styles
• Premium high carbon, heat treated 420 stainless steel friction surface provides durability and corrosion resistance
• Laser cut—not stamped—to reduce warping and distortion caused by residual part stresses
• Precision-ground for optimal brake pad engagement
• CNC-machined billet aluminum carrier is strong, lightweight, and anodized for corrosion resistance
• Full floating design maintains disc alignment under braking and reduces heat transfer from friction material to carrier
• Riveted stainless buttons have more positive retention than c-clips and won't transfer heat to the carrier like aluminum fasteners
• Stainless steel disc spring washers permit the friction surface to float without rattling 
• Hardware (available separately) is required for many Harley-Davidson applications and strongly recommended for all Harley-Davidson motorcycles
• Stringent manufacturing processes yield high-performance, precision braking feel
• Sold individually

A TC Bros. 12.6" front floating brake rotor is an obvious starting point for a custom brake system. A larger rotor gives better leverage to the caliper and increases the swept area in contact with the pads. If you want better braking feel, aggressive stopping, and modern, fresh style for your bike, a floating rotor can deliver. Our bimetallic design yields the best of both worlds—a swept area that hangs tough under aggressive stopping and a carrier that prevents heat transfer. 

This rotor, a 12.6" unit, is maybe better known by its metric designation of 320mm. If that number sounds familiar, that's because it's a common size found on the large metric sport machines fitted with 17" wheels. This disc is explicitly for Harley-Davidson riders who need a disc that's compatible with a Harley wheel but are upgrading to a sport bike or race-rep caliper. The diameter and offset is perfect for use with one of our brake brackets and a Brembo caliper. They'll also work well with popular Tokico swaps.

Choose from a standard floater or our Profile™ design. The waves on the perimeter of those bring a little flair to your bike and help provide greater cooling with increased surface area. The non-directional design on whatever rotor you select is equally at home on single- or dual-disc applications.

TC Bros. recommends use of semi-sintered or full-sintered pads in conjunction with our brake discs. As with any brake service, using new pads is mandatory. In keeping with standard shop practice, completely and thoroughly cleaning the disc(s) using soap and water is required before installation. Washing the friction surface, carrier, and rivets and then drying the rotor(s) is critical to ensure packing oil and rivet lubricant do not contaminate the brake pads.
