Bosch QuietCast Rear Ceramic Brake Pads BC1846 - Low-Dust, Quiet OE-Fit Axle Set

The BOSCH BC1846 QuietCast rear ceramic brake pad set delivers quiet, low-dust stopping performance with OE-style fit and enhanced corrosion resistance.

Engineered by Bosch using decades of braking development, the QuietCast BC1846 rear pads pair a proprietary ceramic friction compound with pre-attached multilayer shims and powder-coated backing plates. This combination targets reliable stopping power, reduced noise, and longer service life while providing an easy, ready-to-install axle set that includes hardware and lubricant where applicable.

How do these pads reduce noise compared with standard replacements?

QuietCast pads use Bosch's multilayer rubber-core shims bonded to the pad backing to damp vibration that causes squeal. The bonded shims and tailored ceramic friction material work together to minimize audible noise across a wide range of speeds and braking pressures.

• Pre-attached OE-style multilayer rubber core shims for vibration control
• Ceramic friction formulation engineered for quieter engagement
• Precision slots and chamfers that prevent edge chatter and harsh contact

What performance and wear characteristics can I expect from the QuietCast ceramic compound?

The ceramic friction material is formulated for consistent pedal feel, predictable initial bite, and lower airborne dust than many semi-metallic options. That means reliable stopping performance with cleaner wheels and fewer brake dust deposits over typical driving conditions.

• Consistent stopping across temperature ranges
• Low-dust output to maintain wheel appearance longer
• Engineered for durable, even wear under normal driving loads

Will these pads resist rust and stay dimensionally stable over time?

To help delay corrosion, the BC1846 backing plates are finished with a protective powder coat that shields steel surfaces from moisture and road contaminants. Bosch also incorporates manufacturing tolerances, slots, and chamfers to maintain fit and reduce glancing wear, improving long-term stability.

• Powder-coated backing plates for improved rust resistance
• OE-style slots and chamfers to ensure consistent fit and reduce uneven wear
• Factory bonding techniques to keep shims secured over service life

What comes in the package and how simple is installation?

The set is supplied for one axle (both rear wheels) and, where applicable, includes necessary hardware and a small tube of synthetic lubricant to reduce sliding resistance at contact points. Because the pads arrive pre-shimmed and finished, installation resembles OE pad replacement procedures for most technicians and DIYers.

• Complete axle set — pads for two wheels
• Hardware kit included when required by application
• Synthetic lubricant for caliper slides and pad contact points

Who is this for: The BOSCH BC1846 QuietCast rear ceramic brake pads are aimed at drivers who want an OE-quality replacement with an emphasis on quiet operation, low dust, and corrosion protection. They suit owners of compatible vehicles (verify exact fitment with your vehicle details), drivers seeking longer-lasting pad life than economy alternatives, and DIY enthusiasts or technicians looking for a straightforward, ready-to-install rear axle pad set.
