Bosch BC2308 rear brake pad for the 2021-2024 Chevrolet Trailblazer and other vehicles is a ceramic pad from the Bosch QuietCast line, built around quiet performance and low brake dust.
- Bosch QuietCast ceramic brake pads use a patented copper-free friction formula that is compliant with 2025 Copper Free legislation.
- The OE style rubber core shim is a pre-attached multilayer design that bonds rubber to steel for lower noise, more strength and corrosion resistance.
- PTFE and rubber coated hardware reduces vibration and noise and prevents binding to the caliper.
- The powder-coated backing plate prevents rust and corrosion.
- A protective transfer layer extends pad and rotor life.
Noise when braking, longer stops or vibration through the pedal can mean the pads are worn, though a sticking caliper or a worn rotor may be behind them instead, so track down the cause first. This listing is one set of four pads for the rear brakes, and the pads on both rear wheels are normally replaced together.
It is a direct-fit replacement for the 2021-2024 Chevrolet Trailblazer and also fits the 2020-2024 Buick Encore GX.
