See the Buyer's Guide tab for engine-level fitment.
- Copper-free friction formula: the QuietCast friction material is 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: reduces vibration and noise while helping prevent binding to the caliper.
- Powder-coated backing plate: resists rust and corrosion for increased brake pad life.
A protective transfer layer is designed to help extend pad and rotor life, and synthetic lubricant is included in all applications to reduce resistance on the sliding contact points. Bosch has carried OE braking heritage since 1927. For even, balanced braking, replace the pads on both sides of the rear axle together as a matched set. If worn rear pads are the cause of squealing, reduced braking, or a low pedal, this set replaces them.
