Bosch Disc Brake Pad Set P/N:BC1878

Quiet, low-dust stops start with the Bosch QuietCast Disc Brake Pad Set BC1878 — a BOSCH brake pad set that drops in as a direct-fit rear replacement for the 2019-2020 Acura RDX and 2016-2023 Honda Civic (see the Buyer's Guide tab for engine-level fitment). These QuietCast pads use a copper-free ceramic and semi-metallic friction formula compliant with 2025 copper-free legislation.

• OE-style rubber core shim: pre-attached multilayer shim bonds 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.
• Protective transfer layer: helps extend pad and rotor life; synthetic lubricant is included in all applications to reduce resistance on sliding contact points.

Rigorously formulated and tested by Bosch engineers, the QuietCast friction material is engineered for a smooth, consistent pedal feel and low dust during everyday street driving — building on Bosch's OE braking heritage since 1927. Sold as a set for one axle; replacing both sides together as a matched pair is recommended for even, balanced braking. If worn pads are the cause of squealing or reduced stopping, this set replaces them.
