Bosch QuietCast BC1779 Rear Ceramic Disc Brake Pads for Audi & VW - Low Dust, Quiet Stops

BOSCH QuietCast BC1779 is a rear axle ceramic disc brake pad set engineered to deliver quieter stops, reduced dust, and long-lasting OE-style performance for compatible Audi and Volkswagen models.

Drawing on Bosch's decades of braking expertise, the QuietCast BC1779 rear pad set combines a proprietary ceramic friction formula with Molded Shim Technology and corrosion-resistant backing plates. The result is a replacement pad that aims to match original equipment fit, feel, and stopping power while minimizing noise and residue. Each kit includes pads for one axle, and when available, a hardware kit plus synthetic lubricant to aid smooth caliper movement during installation.

How do these pads reduce noise and vibration?

Noise-reduction starts with Bosch’s pre-attached multi-layer rubber core shims, which are bonded to the steel backing to dampen vibration. The Molded Shim Technology (MST) minimizes squeal and harsh feedback without adding aftermarket shims, while the ceramic friction formulation runs quieter under typical driving loads.

• Pre-attached multilayer rubber core shims for superior damping
• Molded Shim Technology (MST) integrated at the factory
• Ceramic friction material designed for low-frequency noise control

Will these pads fit my vehicle and match OE performance?

The BC1779 is designed for rear-axle applications on select Audi Q3 and several Volkswagen Golf, Golf Alltrack, GTI, Golf SportWagen, and Passat model years. Bosch engineers shape slots, chamfers, and backing plates to mirror OE geometry so the pads install and operate like factory parts, though trim or engine options can change fit—always confirm with your vehicle-fit checker.

• OE-style slots and chamfers for correct fit and bedding
• Compatible with specific Audi Q3 and VW Golf/Passat model ranges
• Verify fitment against vehicle trim, year, and axle location before purchase

How durable are these brake pads and what protects them from corrosion?

Bosch applies a powder-coated finish to the backing plate to guard against rust and extend service life, while the ceramic compound resists excessive wear and produces minimal dust. The construction focuses on strength at high temperatures and repeated stopping cycles to maintain consistent performance over time.

• Powder-coated backing plates for enhanced corrosion resistance
• Ceramic material engineered for stable wear and low dust
• Factory-bonded shim system reduces debonding and increases durability

What comes in the box and what aids installation?

The BC1779 kit supplies the rear pads for one axle and, when applicable, a hardware kit and synthetic lubricant to reduce sliding resistance on contact points. These items help ensure proper pad seating, smoother caliper operation, and reduced initial noise after installation.

• Pads for both wheels on one axle (rear)
• Hardware kit included where specified by part fitment
• Synthetic lubricant for guide pins and sliding surfaces

Who is this for? The Bosch QuietCast BC1779 is aimed at drivers of compatible Audi Q3 and Volkswagen Golf/Passat vehicles who want an aftermarket pad that closely matches OE fit and braking behavior while emphasizing quieter stops and lower dust. It suits DIY mechanics, independent shops, and anyone replacing rear pads who values long-term corrosion protection and factory-integrated noise control features.
