Bosch QuietCast Ceramic Rear Disc Brake Pads BC1878 – Rear Axle Set, Low Dust & Quiet

BOSCH BC1878 QuietCast rear ceramic disc brake pads are OE-inspired replacement pads engineered for quieter stops, low dust, and durable corrosion resistance for one axle (two wheels).

Built on Bosch's long history in braking systems, the QuietCast BC1878 set combines a ceramic friction formulation with pre-attached multilayer rubber-core shims and powder-coated backing plates. The result is a pad set designed to mimic original equipment fit and feel while reducing noise, limiting rotor contamination from brake dust, and resisting rust for longer service life. This package ships with hardware where applicable and includes synthetic lubricant for sliding contact points to simplify installation and improve operation.

How do these pads reduce brake noise and vibration?

The BC1878 QuietCast pads use Bosch’s multilayer rubber-core shim design bonded to the backing plate to interrupt noise paths and dampen vibration. Combined with chamfers and OE-style slots, the pads minimize harsh engagement and squeal common to lesser replacements.

• Pre-attached multilayer rubber-core shims for improved noise control
• Chamfers and slots to smooth pad-to-rotor contact
• Precision fit to help prevent uneven wear and vibration

What performance can I expect in everyday driving?

The proprietary ceramic friction material delivers consistent stopping performance during typical urban and highway driving without the gritty feel of semi-metallic pads. You’ll notice predictable pedal feel, dependable deceleration, and less airborne brake dust compared with many metallic formulations.

• Ceramic compound tuned for steady braking response
• Low dust output keeps wheels cleaner longer
• Engineered for balanced cold and warmed-up performance

How does Bosch address durability and corrosion resistance?

Bosch applies a corrosion-resistant powder coating to the backing plates to slow rust and preserve pad integrity in wet or salty conditions. The robust bond between shim and steel improves long-term strength, while the included lubricant reduces wear at sliding points to extend pad life.

• Powder-coated backing plates to resist rust
• Molded shim-to-steel bonding for added structural durability
• Included synthetic lubricant and hardware where applicable for smoother operation

Will these fit my vehicle and what comes in the box?

BC1878 is designed as a rear pad set compatible with select Acura and Honda models; fitment depends on model year and trim, so verify vehicle compatibility before buying. Each kit supplies pads for one axle (two wheels) and, where the application requires, comes with the necessary hardware and a small packet of synthetic lubricant for caliper slides.

• Set contains four brake pads (one axle) for rear wheels
• Hardware kit included when application requires it
• Small tube of synthetic lubricant for sliding contact points

Who is this for: The Bosch BC1878 QuietCast rear ceramic brake pad set is aimed at drivers who want an OE-style replacement that emphasizes quieter stopping, reduced wheel contamination from brake dust, and improved corrosion resistance. It’s a good match for owners of compatible Acura and Honda vehicles seeking long-lasting, low-noise pads without stepping up to race-focused compounds.
