DBA 4000 Series T3 Front Brake Rotor
Upgrade the front braking performance of your Toyota Land Cruiser J300/J310 or Lexus LX600 with the DBA43770S 4000 Series T3 slotted brake rotor. Designed as a direct-replacement, single-piece performance rotor, it provides improved heat management, consistent braking response, and dependable performance for demanding street, towing, off-road, and performance-driving applications.
DBA’s T3 bi-directional slot pattern helps evacuate brake dust, gases, and debris from the pad surface while promoting consistent pad contact. The curved slot design also helps reduce vibration and supports a smooth, responsive pedal feel.
The vented high-carbon rotor uses DBA’s Kangaroo Paw internal ventilation system, featuring a series of diamond- and teardrop-shaped pillars that increase internal surface area and improve cooling compared with a conventional straight-vane design. This construction helps reduce brake fade and maintain rotor stability during repeated braking.
DBA’s temperature-monitoring markings provide a visual indication of the maximum temperature reached by the rotor, helping with brake-system evaluation during demanding use.
