FAQs

Does this package include a pair of discs?

This guide covers the 09.B855.51 unit; please verify if your purchase includes a single disc or a set.

What is the minimum thickness for this disc?

The minimum thickness is 30mm, as indicated by the built-in markings on the disc.

Can I use these on a non-sports package vehicle?

No, these are specifically designed for vehicles with SA codes 950 and P96.

Do I need to wash off the coating before use?

No, the protective coating is designed to be ready for installation and will clear naturally during the first few braking cycles.

What is the bolt hole configuration?

The disc features a 5-bolt hole pattern.

What is the required tightening torque?

The tightening torque for this brake disc is 130 Nm.

Troubleshooting

Brake squeal or noise shortly after installation

Ensure that the pad bedding-in process was followed correctly and that all clips/hardware are properly lubricated and torqued.

Premature corrosion appearing on the disc

While the disc is UV-coated, excessive use of acidic wheel cleaners can degrade the finish. Use pH-neutral cleaning products.

Uneven wear patterns

Check for stuck brake calipers or uneven pressure distribution, and verify the wheel alignment.

Pros and Cons

Pros

  • Significantly improved cooling efficiency via PVT technology
  • High resistance to thermal cracking and heat fatigue
  • Durable anti-corrosion UV-coating
  • Easy-to-read minimum thickness indicators
  • Direct fit for specific Mercedes-Benz sports models

Cons

  • Specific to front axle installation only
  • Limited compatibility to specific Mercedes-Benz chassis
  • Higher maintenance requirements associated with drilled performance rotors

Setup, Compatibility & Care

This brake disc is designed specifically for the front axle of the Mercedes-Benz CLS (C218) and CLS Shooting Brake (X218) with sports package SA codes 950 and P96. When installing, it is critical to observe the manufacturer's specified tightening torque of 130 Nm to ensure the longevity of the mounting hardware. Before installation, ensure the wheel hub is clean and free of rust to prevent run-out issues. While the protective coating is designed for durability, avoid using harsh acidic wheel cleaners that can strip the finish over time. Regular visual inspections are recommended using the built-in wear markers; ensure that the thickness never drops below the 30mm safety threshold.
