Rolls-Royce Cullinan Rear Brake Rotor Set - 6871258

Are the rear brake rotors on your Rolls-Royce Cullinan vibrating, scoring or worn below minimum thickness? Part number 34216871258 is the correct rear brake rotor for the Rolls-Royce Cullinan — covering all variants from 2018 to 2024 including the Black Badge. This listing supplies both rear rotors as a matched pair.

The Cullinan's rear brake rotors measure 398mm in diameter and 28mm in thickness — large ventilated discs that work in conjunction with the rear Brembo 4-piston calipers to deliver smooth, progressive and silent stopping power from the rear axle. On a vehicle weighing 2,660 kilograms, the rear braking system carries significant responsibility in balanced weight distribution under braking — and maintaining the correct rotor specification is essential to preserve the Cullinan's characteristic stability and composure.

Rear rotors must always be replaced as a pair. Replacing only one rotor introduces an imbalance in friction and braking force across the rear axle — on a vehicle of the Cullinan's weight and capability this is both inefficient and potentially unsafe.

These rotors are manufactured to OEM specification and are a direct fitment replacement for the factory units on all Cullinan variants.

Part number: 34216871258 (also referenced as 6871258 and 3421 6871258)

Signs your rear brake rotors need replacing: Vibration or pulsation felt through the brake pedal or vehicle body under braking, grinding or clicking noise from the rear axle when braking, visible scoring or deep grooves on the rotor surface when inspecting through the wheel, rotor thickness at or below the manufacturer's minimum wear limit, or uneven braking feel with the vehicle pulling to one side.

Fitment: Rolls-Royce Cullinan — 2018 to 2024, Rolls-Royce Cullinan Black Badge — 2020 to 2024.
