Products
The Toyota Floating Rear Brake disc adopts a true two-piece floating design, comprising a central aluminium alloy hat and a cast iron friction ring connected by high-strength alloy steel drive pins . This floating mount system allows the friction ring to expand radially and axially relative to the hat during thermal expansion . Unlike rigid one-piece discs where differential thermal expansion causes warping and judder, the floating design absorbs thermal stress, maintaining a flat friction surface even under sustained high-temperature braking.
The floating mount system allows the rotor to self-centre between the brake pads . This automatic centring ensures even pad-to-disc contact on both sides, maximising braking efficiency and minimising uneven pad wear—a critical attribute for rear brake applications where parking brake mechanisms add complexity.
The companion brake pads are formulated with friction compounds that match Toyota's original equipment specifications. The material chemistry ensures stable friction output across a wide operating temperature range, from cold morning starts to sustained high-temperature braking . This OE-equivalent approach ensures braking performance, pedal modulation, and wear characteristics align with the vehicle's original design intent.
The friction ring is manufactured from G3000 high-carbon cast iron, a material specification recognised for superior thermal stability and wear resistance . The elevated carbon content promotes the formation of microscopic graphite flakes within the iron matrix, providing self-lubricating properties that reduce friction surface adhesion and minimise abrasive pad wear.
The high-carbon metallurgy significantly improves resistance to heat-check cracking—a common failure mode under repeated high-temperature braking cycles. This ensures the disc maintains structural integrity over an extended service life, even under the demands of mountainous terrain or towing applications.
The pad compound is engineered for extended service intervals, with wear characteristics optimised for the typical loads and braking energies of Toyota vehicles . The combination of the precision disc surface and the wear-resistant pad formulation works synergistically to distribute wear evenly across the pad surface, maximising pad service life.
The pad formulation produces significantly less brake dust compared to traditional alternatives . Reduced dust generation keeps alloy wheels cleaner and contributes to overall braking system hygiene—less dust accumulation on the disc surface means more consistent pad-to-disc contact and fewer opportunities for noise-causing debris to embed in the pad material.
The brake pads are manufactured using environmentally conscious materials that comply with current automotive environmental regulations . The friction formulation avoids the use of restricted substances, making these pads a responsible choice for environmentally aware vehicle owners without sacrificing performance.
