Bosch QuietCast Rear Ceramic Brake Pads BC1391 — OE-Style, Low-Dust, Quiet Performance

BOSCH BC1391 QuietCast rear ceramic disc brake pads are a premium OE-style replacement designed for quiet, low-dust stopping with durable corrosion protection.

The Bosch QuietCast BC1391 set is engineered as a direct-fit rear axle replacement for a range of Lexus and Toyota models, combining a proprietary ceramic friction blend with Bosch innovations to deliver consistent braking performance. These pads arrive ready for installation with hardware where applicable and synthetic lubricant to reduce mounting friction. Built-in design features aim to reduce noise, limit dust, and extend pad life compared with basic aftermarket alternatives.

How do these pads reduce noise during braking?

QuietCast pads use multilayer rubber-core shims that are factory-attached to the backing plate. The layered shim construction and precise bonding minimize vibration transfer from pad to caliper, helping stops feel solid and quiet under normal driving conditions.

• Molded Shim Technology (MST) for bonded rubber-to-steel shims
• Pre-attached OE-style multilayer shims to cut rattles and squeal
• Chamfered edges and slots to reduce edge noise and uneven wear

What performance can I expect from the ceramic friction material?

The ceramic compound in these pads is formulated to deliver reliable stopping power across everyday driving situations while producing less visible brake dust than many semi-metallic pads. Bosch engineers test the compound to balance friction consistency, pedal feel, and wear characteristics for long-term use.

• Ceramic formula engineered for steady stopping performance
• Low-dust operation for cleaner wheels and less maintenance
• Stable friction across typical temperature ranges encountered in street driving

How does Bosch protect the pad from corrosion and extend service life?

Each backing plate is finished with a rust-resistant powder coat to prevent corrosion where the pad mounts to the caliper, preserving fit and preventing binding over time. Proper backing-plate protection helps maintain pad alignment and prevents premature hardware failure that can shorten service life.

• Powder-coated backing plates resist rust and extend product life
• OE-style slots and chamfers reduce glazing and promote even wear
• Included synthetic lubricant lowers sliding resistance at contact points

What comes in the box and how do I confirm fitment?

The BC1391 rear pad set supplies pads for one axle (two wheels) and includes a hardware kit when required by the application, plus a small tube of synthetic lubricant for the caliper slides. Always verify vehicle compatibility with your fitment tool or by checking model/year fit notes, since trim level or brake options can change requirements.

• Pads for one rear axle (2 wheels) plus hardware kit as applicable
• Synthetic lubricant for reduced sliding resistance on contact points
• Compatibility with many Lexus and Toyota models — confirm exact fitment before purchase

Who is this for: The BOSCH BC1391 QuietCast rear ceramic pad set is intended for owners of compatible Lexus and Toyota vehicles seeking a high-quality, direct-replacement pad that emphasizes quiet operation, cleaner wheels, and long-lasting corrosion resistance. It suits drivers who want OE-style fit and feel without upgrading to high-performance racing compounds — ideal for daily commuting, family vehicles, and drivers who value low maintenance and dependable braking behavior.
