Bosch QuietCast BC1391 Rear Ceramic Brake Pad Set — OE-Style, Low Dust & Quiet Stops

BOSCH BC1391 QuietCast rear ceramic disc brake pads are a premium OE-style replacement set engineered for quiet stops, low dust, and long-lasting corrosion resistance.

Built on Bosch's decades of braking experience, the BC1391 QuietCast pads combine a proprietary ceramic friction compound with Molded Shim Technology (MST) and powder-coated backing plates to deliver reliable performance for select rear-wheel applications. This set includes pads for one axle (two wheels), plus any applicable hardware and synthetic lubricant to ease installation and reduce sliding friction. Fitment varies by vehicle year and trim, so verify compatibility with your vehicle before purchase.

How do these pads reduce noise and vibration?

QuietCast pads use Bosch's pre-attached multilayer rubber-core shims and MST to dampen harmonic vibrations and reduce brake squeal. The bonded shim assembly improves the connection between pad material and backing plate for consistent, quieter operation under a wide range of driving conditions.

• Molded Shim Technology (MST) for enhanced noise suppression
• Pre-attached multilayer rubber-core shims that absorb vibration
• Precision slots and chamfers that help prevent edge chirp

What performance and wear characteristics can I expect?

The BC1391 pads are formulated with a ceramic friction material engineered for steady stopping performance and minimal airborne dust. Their composition balances braking power and pad longevity, giving dependable deceleration while keeping wheels cleaner than many semi-metallic alternatives.

• Ceramic compound for consistent friction and reduced brake dust
• Durable backing plate with powder-coat to resist corrosion
• OE-style fit and finish for predictable wear patterns and service life

What comes in the box and is it easy to install?

The package contains one axle’s worth of rear brake pads (two wheels), and where applicable, the matching hardware kit plus a tube of synthetic lubricant for contact points. The pads are designed to match OE slot and chamfer patterns for straightforward replacement, but basic brake system experience or a professional installation is recommended.

• Complete rear pad set for one axle with hardware (when applicable)
• Synthetic lubricant included to reduce sliding resistance
• OE-style slots and chamfers to ensure proper fit and ease of installation

Which vehicles are these rear pads compatible with?

The BC1391 set fits a range of Asian, domestic, and European models; Bosch lists specific Lexus and Toyota applications for rear installations. Because model years and trim levels affect fitment, always check the vehicle fitment tool or the manufacturer’s specifications before ordering.

• Common fits include select Lexus GS, IS, RC, RX models and Toyota Highlander, Mirai, Prius V, Sienna
