Bosch QuietCast Rear Ceramic Brake Pads BC1391 — Rear Axle Set, Low Dust & Quiet Performance

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

Built from Bosch’s decades of braking experience, the QuietCast BC1391 uses proprietary ceramic friction material and Molded Shim Technology (MST) to deliver predictable braking performance and reduced noise compared with many aftermarket options. This rear axle kit includes pads for two wheels, a hardware kit where applicable, and synthetic lubricant to optimize sliding components during installation.

How do these pads reduce noise and vibration?

The QuietCast line relies on Bosch’s pre-attached multilayer rubber-core shims and precision bonding to isolate vibration and dampen harmonic noise. The MST shims improve the interface between pad and caliper surface so you hear less brake squeal under light- to medium-duty braking.

• Pre-attached OE-style multilayer rubber core shims for vibration control
• Precision bonding between shim and steel backer to prevent separation
• Ceramic friction formulation tuned for smoother engagement

What performance and durability features should I expect?

These pads combine ceramic friction compounds with powder-coated backing plates to resist rust and preserve structural integrity over time. OE-style slots and chamfers enhance fit and reduce edge crumbling, while the included lubricant lowers drag at sliding contact points for consistent pedal feel.

• Ceramic friction material engineered for consistent stopping and low dust
• Powder-coated backing plate for corrosion resistance and longer life
• Slots and chamfers for improved bedding-in and fitment

Will the BC1391 fit my vehicle and what comes in the kit?

The BC1391 is designed to match rear-axle specifications for a range of Lexus and Toyota models; exact fit depends on vehicle year and trim, so verify fitment with your vehicle lookup. Each box supplies pads for one axle (two wheels), any vehicle-specific hardware where applicable, and a small tube of synthetic lubricant for sliding surfaces.

• Pads for one axle (two wheels) included
• Hardware kit included when required by application
• Synthetic lubricant to reduce sliding resistance during installation

How do Bosch QuietCast pads compare with OE and other aftermarket pads?

Bosch designs QuietCast pads to mirror original equipment fit and function while adding noise-control and corrosion-resistant upgrades. The ceramic compound produces less visible dust than many semi-metallic pads, and Bosch’s MST shims aim to match or improve upon OE NVH (noise, vibration, harshness) standards without sacrificing stopping capability.

• OE-style fit and form for straightforward replacement
• Lower visible brake dust compared to many semi-metallic competitors
• Enhanced corrosion protection versus uncoated back plates

Who is this for: The BOSCH QuietCast BC1391 rear ceramic pad set is aimed at drivers of compatible Lexus and Toyota vehicles who want a direct-replacement pad that balances quiet operation, clean wheels, and long-term durability. It’s a solid choice for everyday commuters, families, and owners preferring OE-style performance with upgraded noise control and corrosion resistance.
