Bosch QuietCast Rear Ceramic Brake Pads BC1878 — Rear Axle Set, Low Dust & Quiet Stop

Designed by a company with braking patents stretching back to 1936, the QuietCast BC1878 combines Bosch’s Molded Shim Technology (MST), ceramic friction formulation, and corrosion-resistant backing plates to deliver a direct-fit rear pad set for many Asian, domestic, and European vehicles. The package includes pads for one axle (two wheels), a hardware kit where applicable, and synthetic lubricant for sliding contact points, making installation straightforward for DIYers and technicians alike.

How do these pads reduce noise and vibration during braking?

Noise suppression starts with Bosch’s OE-style multilayer rubber core shims, molded for a high-quality bond with the steel backing plate. That connection dampens vibration and reduces squeal without sacrificing pedal feel.

• Molded Shim Technology (MST) for superior rubber-to-steel adhesion
• Pre-attached multilayer shims engineered for OEM-level damping
• Precision slots and chamfers to minimize uneven contact and chatter

What performance can I expect from the ceramic friction material?

The proprietary ceramic compound is formulated and tested by Bosch engineers to offer consistent stopping power across everyday driving conditions while producing less brake dust than many semi-metallic alternatives. It balances durability, rotor friendliness, and predictable modulation at typical street temperatures.

• Ceramic formula for quieter operation and reduced dust
• Engineered for reliable stopping performance in urban and highway use
• Designed to be rotor-friendly for longer rotor life under normal driving

Will these pads resist corrosion and fit my vehicle accurately?

BC1878 pads feature powder-coated backing plates that help prevent rust and corrosion, extending pad life in wet or salty environments. Bosch uses OE-style slots and chamfers to ensure precise contact patterns and consistent fitment; verify fitment using the vehicle-specific fit checker before purchase, since trim level and engine options can affect compatibility.

• Powder-coated backing plates for increased corrosion resistance
• OE-style slots and chamfers for consistent pad-to-rotor contact
• Includes hardware kit and synthetic lubricant where applicable for correct installation

How easy is installation and what comes in the box?

Bosch supplies everything needed for a standard rear pad replacement in one axle sets: two pads per wheelset, any required mounting hardware when available, and a tube of synthetic lubricant to reduce sliding resistance at contact points. That combination reduces preparation time and helps ensure correct operation right after installation.

• Complete rear axle pad set — pads for two wheels
• Hardware kit included where applicable for secure mounting
• Synthetic lubricant for caliper slide surfaces to improve movement and reduce noise

Who is this for? If you drive a compatible Acura, Honda, or other vehicle where the BC1878 matches the rear brake application and you want a reliable, quiet ceramic pad with OEM-inspired features, the Bosch QuietCast BC1878 is a practical choice. It suits owners who prefer lower dust, corrosion-resistant backing plates, and a plug-and-play replacement that includes necessary hardware and lubricant. Always confirm vehicle fitment—especially trim and engine options—before ordering.
