Tired of sluggish or uneven braking? This Hydrastar Disc Brake Kit with electric-over-hydraulic actuator delivers smooth, consistent stops even at highway speeds. The system creates fast, even brake response through your existing in-cab brake controller, so you get confident control every time you hit the pedal. The complete kit upgrades your tandem-axle setup to disc performance, cutting your stopping distance compared to drum brakes.
No need to replace entire hub-and-rotor assemblies. The 12" cast iron rotors slip right over your existing idler hubs and are held in place by your current wheel bolts. That design makes it easy to convert your setup or replace just one part later without junking a full assembly. The rotors meet SAE specs and include venting that helps move air through the core to shed heat and reduce fade on long grades.
Every part in this kit is matched for 6,000-lb axle capacity and a 6 on 5-1/2" bolt pattern. You get four dacromet-coated disc brake end kits with calipers, mounting brackets, and hardware. The package also includes a hydraulic line kit for tandem axles with pre-fitted inverted flare nuts, brass fittings, nylon hose clamps, and self-tapping screws—everything sized to connect the system securely.
Each rotor and caliper is dacromet coated to resist rust and corrosion, keeping performance solid in wet or humid conditions. The actuator carries a 2-year warranty, while brakes and components are backed for 1 year. With fewer moving parts than drum setups and corrosion protection built in, this kit is designed for reliable braking season after season.
