Frequently Asked Questions

Q: What are the specifications of the TO 00591-76120-81 brake disc?
A: The TO 00591-76120-81 is a Toyota OEM vented brake disc for electric lift trucks with the following specifications: 345 mm outer diameter, 112 mm bore diameter, 18 mm thickness, and 5-stud mounting configuration. The vented design allows for improved heat dissipation during braking cycles, reducing fade and extending service life.

Q: Which Toyota electric lift truck models use this brake disc?
A: The TO 00591-76120-81 brake disc is designed for various Toyota electric lift truck models, typically mounting on rear axle brake assemblies. Verify your equipment model, year, and axle configuration against Toyota documentation. Disc dimensions and stud patterns must match your existing brake caliper and hub assembly before ordering.

Q: What material is this brake disc made from and why?
A: The TO 00591-76120-81 brake disc is manufactured from high-grade cast iron, which provides excellent heat dissipation, friction consistency, and durability under repeated braking loads. Cast iron resists warping and maintains flatness during thermal cycling, critical for stable brake pedal feel and consistent stopping distance on material handling equipment.

Q: What is the expected service life of this brake disc?
A: Under normal electric lift truck operating conditions with routine maintenance, the TO 00591-76120-81 brake disc can provide 2-4 years of service life. Service life depends on operating hours, brake pad wear, and storage environment. Inspect the disc annually for scoring, cracks, or thickness loss. Replace if thickness drops below 16 mm or if visible damage compromises braking performance.

Q: How should this brake disc be maintained?
A: Regularly inspect the TO 00591-76120-81 for rust buildup, surface scoring, and thickness degradation. Clean the disc surface to remove brake dust and corrosion. Verify that the 5-stud mounting bolts remain tight and that the disc sits parallel to the brake caliper. Replace brake pads promptly to minimize excessive disc friction and wear.

Q: Are there cross-reference or equivalent brake disc part numbers?
A: No known cross-reference or superseding part numbers are available for TO 00591-76120-81. This is a Toyota OEM brake disc. Substitute discs must match all specifications including outer diameter of 345 mm, bore diameter of 112 mm, thickness of 18 mm, and 5-stud mounting configuration to ensure safe brake assembly fitment.
