Designed for quiet, smooth rear braking, the Bosch brake rotor 53011518 is a QuietCast disc brake rotor backed by Bosch's OE braking heritage. It is a direct-fit replacement for many vehicles, among them the 2020-2023 Toyota GR Supra, 2021-2023 BMW 430i and 2022-2023 BMW 430i Gran Coupe. See the "Vehicles it fits" section for the full list.
This rear rotor gives the brake pads the surface they clamp against, turning the vehicle's motion into heat as it slows. This Bosch QuietCast brake rotor combines heat-flowed castings with 100% precision balancing.
- QuietCast brake rotor: Part of Bosch's QuietCast rotor line.
- Heat-flowed castings: Help promote consistent wear, intended to support quiet operation and long product life.
- 100% precision balanced: Designed for smooth operation and to help minimize pedal pulsation.
- Bosch OE heritage: Draws on 77 years of OE braking experience, with a focus on quality, strength and durability.
Signs a rotor may need replacing include a pulsating brake pedal, grinding or scraping noises, deep scoring or grooves on the braking surface, or a rotor worn below its minimum thickness. Replacing both rear rotors together is recommended for even, balanced braking.
