BOSCH QuietCast BC1391 Rear Ceramic Brake Pads - Quiet, Low Dust

In this review the focus is on the BOSCH QuietCast BC1391 rear ceramic brake pad set and why it appeals to drivers who want quieter braking without sacrificing stopping power. The bottom line: these pads are for owners of compatible Lexus and Toyota models who want an OE-style, low-noise replacement that arrives ready to install. The review finds the QuietCast pads deliver noticeably reduced noise and low dust thanks to Bosch's ceramic friction material and Molded Shim Technology, while also including the hardware and lubricant needed for straightforward installation.

Key Features

• Molded Shim Technology: Pre-attached multilayer rubber core shims reduce noise and maintain a strong bond between rubber and steel for quieter stops.
• Ceramic Friction Material: Bosch-formulated ceramic compound provides consistent stopping power with lower dust than many semi-metallic pads.
• Powder-Coated Backing: The backing plate is powder-coated to resist rust and corrosion, extending pad life in wet or salty conditions.
• Ready to Install: The set includes pads for one axle, the hardware kit where available, and synthetic lubricant to ease sliding contact and reduce reassembly rattles.
• Precision Fitment: Designed to match many Lexus and Toyota rear applications, the pads aim to fit like OE parts for an easier replacement.

Who It's For

The QuietCast BC1391 is best for owners of compatible Lexus models such as GS, IS, RC and RX, and Toyota models including Highlander, Prius V, Mirai and Sienna who prioritize quiet braking and keep an eye on dust and pad longevity. It suits DIYers who appreciate a pad set that ships with hardware and lubricant so the job is more straightforward.

Drivers who need pads for non-listed years or trims should verify fitment before buying; a few customers reported fit issues on older or uncommon model years, so those users or professional service shops fitting nonstandard variants may want to confirm compatibility first.

Pros & Cons

Pros

• Quieter operation from Bosch's OE-style multilayer shims, reducing squeal and chatter.
• Low dust ceramic formulation keeps wheels cleaner compared with many stock pads.
• Includes hardware and lubricant so the set is essentially ready to install for one axle.

Cons

• Fitment can vary by trim and year, so some buyers may need to verify vehicle-specific compatibility.
