Bosch QuietCast Rear Ceramic Brake Pads BC1879 — OE-fit, Low-Dust Quiet Performance (Axle Kit)

BOSCH QuietCast BC1879 rear ceramic brake pads provide OE-level stopping performance, quiet operation, and low-dust braking in a ready-to-install axle kit.

Built from Bosch's decades of brake engineering, the QuietCast BC1879 set is a rear-axle replacement designed for many modern Asian, domestic, and European models. These pads combine a ceramic friction formulation, pre-attached multilayer rubber-core shims, and a corrosion-resistant backing plate to deliver consistent, quiet braking while minimizing rotor wear and dust buildup. The kit arrives complete with pads for both wheels on one axle, hardware where applicable, and synthetic lubricant for sliding contact surfaces.

How do these pads reduce noise compared with standard replacements?

The QuietCast BC1879 pads use Bosch Molded Shim Technology (MST) with pre-attached multilayer rubber-core shims that absorb vibration at the pad-to-caliper interface. That engineered bond lowers squeal and harshness without adding complex installation steps.

• Molded, multilayer rubber-core shims for vibration damping
• Pre-attached OE-style shims ensure consistent fit and contact
• Precision slots and chamfers reduce vibration hotspots

What performance and wear characteristics can I expect?

Bosch formulates the QuietCast ceramic friction compound for predictable bite, progressive pedal feel, and low dust. The ceramic blend is balanced to help protect rotors while still delivering dependable stopping power in everyday driving conditions.

• Ceramic friction material engineered for stable performance and reduced dust
• Powder-coated backing plates resist rust and extend pad life
• OE-style slot and chamfer geometry improves contact and reduces uneven wear

Will these pads fit my vehicle and come ready to install?

The BC1879 set is intended for specific rear applications; fitment depends on make, model, and trim. The package includes the pads for one axle, a hardware kit where applicable, and synthetic lubricant to ease installation and reduce sliding resistance.

• Includes pads for both rear wheels (one axle) and hardware where available
• Synthetic lubricant provided for slider contact points
• Confirm compatibility using the vehicle fit checker—trim/engine may affect fit

How does Bosch ensure durability and corrosion resistance?

Bosch applies a powder-coat finish to the backing plates to slow corrosion, and uses manufacturing controls inherited from their OE brake heritage to maintain consistent material strength. These measures help the pads last longer in environments prone to rust and road salt.

• Powder-coated steel backing plates resist rust and corrosion
• Industry-tested bonding and material standards from Bosch OE experience
• Quality-controlled slots, chamfers, and shim attachment for reliable service life

Who is this for: The Bosch QuietCast BC1879 rear ceramic brake pad set suits owners of compatible Toyota and Lexus models (and other select vehicles) who want an OEM-quality replacement that prioritizes quiet braking, low dust, and corrosion resistance. It’s a strong choice for drivers seeking a direct-fit aftermarket pad that’s easy to install, delivers consistent braking feel, and extends component life in everyday driving and light-duty conditions. Always verify fitment for your exact year, trim, and axle before purchase.
