Kodiak Disc Brake Kit - 13" Rotor - 8 on 6-1/2 - E-Coat - 9/16" Bolts - 8K Dexter Disc Kit

Kodiak Trailer Brakes - K2R89DDE

E-coated rotors, calipers and mounting brackets are included with this 2-wheel-assembly disc brake kit. Designed for 8,000-lb Dexter axles and 16" and larger wheels. Requires 9/16" wheel bolts.

Features:

• Brake assemblies make it easy to change from an idler axle to a disc brake axle
• Disc brakes deliver better performance than drum brakes
  • More consistent stopping, even at highway speeds
  • Dramatically shorter stopping distance
• Maintenance costs are lower than for drum brakes
  • Fewer moving parts to maintain, repair and replace
• E-coat finish provides corrosion resistance for freshwater and limited saltwater use
• Slip-on, cast iron, over-the-hub rotors
  • Fit over standard idler hub and are held in place by wheel and wheel bolts
  • Remove easily for maintenance - no need to replace entire hub-and-rotor assembly if only hub or rotor becomes damaged
  • Increase distance from hub face to hub face by 1/2"
  • Prevent heat-related damage with vented design that effectively dissipates heat
• Cast iron calipers are self-adjusting for smooth, equal braking
  • Cast iron construction does not flex like aluminum
  • Low-drag design retracts piston farther than other calipers for a cooler-running brake
  • Silver-cadmium-plated piston is 2-1/2" in diameter - 30 percent larger than other brands
    • More braking torque than the competition
  • High-performance, ceramic brake pads
• Ductile iron mounting brackets provide strength and durability
  • Side-support design ensures that load is placed on bracket, not bolts
  • Extra embossing for additional thread contact ensures tight, secure mounting for caliper guide bolts
  • 4-Bolt brake flange mounting configuration - weld-on flange sold separately
• Kit includes 2 assemblies
  • 2 E-coated, cast iron rotors
  • 2 E-coated, cast iron calipers
  • 2 E-coated, ductile iron caliper-mounting brackets
  • 4 Stainless steel caliper-mounting bolts
• Hydraulic brake actuator and lines (sold separately) are required for brakes to be activated
  • Requires psi rating of at least 1,500

Disc Brakes

More and more people are switching their trailers over to disc brakes, and with good reason. Disc brakes deliver consistent braking - even at highway speeds - unlike drum brakes, which often show a substantial drop in braking torque at higher speeds. In addition, disc brakes offer a substantially shorter stopping distance than drum brakes.

Disc brake calipers have only one moving part, rather than the many found in drum brakes. This means that there are fewer parts to maintain, fewer parts to get damaged and fewer parts to have to repair or replace, thus reducing maintenance costs.

Over-the-Hub Rotors for Easy Replacement

Kodiak's slip-on, cast iron rotor makes it easy to convert an idler axle to a disc brake axle. Simply place the rotor over your hub. It is most often wheel bolt piloted for a loose fit and then held in place by the wheel itself. With a separate rotor and hub, you can easily repair or replace one element of your brake system without having to junk the whole thing.

The rotor is made from cast iron, matching SAE specifications. Cast iron is ideal for high-temperature operations and offers a favorable friction coefficient to ensure adequate stopping power. Kodiak's rotors are vented to effectively dissipate heat, dramatically reducing the incidence of heat-related damage.

Calipers

Kodiak calipers are constructed of cast iron to prevent flexing. Less flex means more braking torque, resulting in smooth, even braking every time. The corrosion-resistant stainless steel piston is 30 percent larger than standard pistons, ensuring shorter stopping distance and increased torque. In addition, the unique low-drag design of Kodiak's calipers allows the piston to retract farther than in most standard models, giving you a cooler-running brake.

Mounting Brackets

Designed for axles with 4-bolt brake flange configurations, the included mounting brackets are made of heavy-duty ductile iron that is embossed to provide additional threading for guide bolts. The added thread strength ensures a tighter, more secure connection between the caliper and bracket. Another unique feature of Kodiak's brackets is the side-support angle, which guarantees that the load is carried by the bracket, rather than the bolts.
