Load Rite 10″ AutoFlex Knott Disc Brake Kit

The Load Rite 10″ AutoFlex Knott Disc Brake Kit represents a proven solution for trailer operators and vehicle enthusiasts upgrading braking performance on medium-duty applications. Designed around the trusted Knott brake mechanism, this 10-inch disc system delivers reliable stopping power for trailers in the 3,000 to 7,000 lbs GVWR range. Whether you're replacing worn hydraulic drums or modernizing an older setup, this kit addresses the core demand for smoother, more responsive braking with less maintenance than traditional drum systems.

The AutoFlex design integrates a self-adjusting caliper assembly and corrosion-resistant rotor geometry that minimizes fade under sustained braking. The 10-inch disc diameter provides superior heat dissipation compared to smaller rotors, critical when descending grades or towing in alpine terrain where brake temperature can exceed safe limits. Knott's engineering ensures pad wear is distributed evenly, extending service intervals and reducing replacement costs over the brake system's lifespan. The hydraulic actuation is direct and linear, translating driver input into consistent deceleration without the lag or sponginess common in older mechanical or cable-actuated systems.

This kit suits DIY restorers, fleet operators, and serious trailer enthusiasts who demand OEM-grade braking without OEM pricing. Installation requires basic mechanical skill—caliper mounting, rotor alignment, and hydraulic line routing are straightforward on most trailer frames. Compatibility spans both drum-brake-equipped trailers undergoing retrofit and new-build projects where disc brakes are specified from the outset. At 28.4 lbs per unit, the brake assembly is manageable for single-technician installation, and Load Rite's track record ensures parts availability and community support for maintenance.
