Rear Brake Pad for 2019-2024 BMW 330i & More - Bosch BC2221

Quiet, confident stopping starts with the right BOSCH brake pad, and the Bosch QuietCast Disc Brake Pad Set (BC2221) is a rear-axle replacement set built for the listed applications. These Bosch QuietCast brake pads install on the rear of many vehicles, among them the 2020-2021 Toyota GR Supra, 2022-2023 BMW 230i and 2023-2024 BMW 230i xDrive. See the "Vehicles it fits" section for the full list.

• Copper-free friction formula: Bosch's patented friction formula is copper-free and compliant with 2025 copper-free legislation.
• OE-style rubber-core shims: pre-attached multilayer shims bond rubber to steel for lower noise, added strength, and corrosion resistance.
• PTFE & rubber-coated hardware: helps reduce vibration and noise while preventing the pads from binding to the caliper.
• Powder-coated backing plate: resists rust and corrosion to help extend the service life of the brake pad.
• Protective transfer layer & synthetic lubricant: designed to help extend pad and rotor life, with synthetic lubricant included for the sliding contact points.

Worn pads can show up as squealing, reduced braking response, or a grinding noise; if the rear pads are the cause, this set replaces them. For even, balanced braking, service both rear wheels together as a matched set and inspect the rotors.
