Installation instructions for ZIMMERMANN 100.3370.70

1. Replace brake discs in pairs to ensure balanced braking performance and optimal weight distribution.
2. Remove the wheels and carefully detach the brake caliper. Support the caliper securely to prevent stress on the brake lines.
3. Remove the old disc: loosen the retaining screws. For seized screws, apply penetrating oil and use gentle percussion with a brass hammer.
4. Thoroughly clean the hub surface and wheel bolts, removing all rust, debris and old thread-locking compound.
5. Install the new floating brake disc, ensuring the aluminium hub is properly seated. Apply appropriate torque to mounting bolts.
6. Install new brake pads and refit the caliper, torquing bolts to manufacturer specifications.
7. Bedding-in procedure: perform 8-12 progressive braking cycles from 80 to 30 km/h, allowing cooling periods between applications to properly condition the perforated surface.

Is the ZIMMERMANN 100.3370.70 compatible with Audi A6 C6 ESP systems?

Yes, this floating brake disc is compatible with most Audi A6 C6 and A6 C6 Avant models equipped with ESP, ABS and other electronic stability systems. The disc maintains original specifications for sensor compatibility.

What are the benefits of the aluminium brake disc hub in the ZIMMERMANN 100.3370.70?

The aluminium brake disc hub reduces unsprung weight by approximately 2-3 kg per disc compared to conventional designs, improving suspension response and reducing brake fade under heavy use typical in Audi A6 applications.

How does the floating design benefit Audi A6 C6 braking performance?

The two-part floating brake disc design allows thermal expansion without warping, crucial for the Audi A6's high-performance braking requirements. This prevents brake judder and maintains consistent pedal feel during extended highway driving.

Do the brake pads need to be replaced at the same time as the ZIMMERMANN brake disc 100.3370.70?

Yes, it is essential to replace brake pads when installing new floating brake discs. The perforated surface requires proper pad bedding to achieve optimal friction characteristics and prevent uneven wear patterns.

Is the ZIMMERMANN brake disc 100.3370.70 ventilated or solid?

This brake disc features advanced ventilated and perforated design. The internal cooling vanes combined with surface perforations provide exceptional heat dissipation, essential for the Audi A6's performance capabilities.

How should new brake discs be properly bedded in?

During the first 300 km, avoid aggressive braking and allow gradual heat cycling. The perforated surface requires careful bedding to develop the optimal friction layer between disc and pads.

What is the outer diameter and thickness of this brake disc?

The outer diameter is 356 mm with a thickness of 28 mm – specifically engineered for Audi A6 C6 front brake systems requiring maximum stopping power and heat management.

Is this brake disc suitable for vehicles with ABS?

Yes, the FORMULA Z COAT Z 100.3370.70 is compatible with most ABS-equipped vehicles. The floating design maintains precise tolerances required for proper ABS sensor function.

Do I need special tools to install the ZIMMERMANN brake disc?

Installation requires standard brake service tools plus a torque wrench capable of accurate settings up to 150 Nm. The floating disc design may require specific techniques for proper hub alignment during installation.

What are the advantages of the ZIMMERMANN brake disc 100.3370.70 compared to other models?

The FORMULA Z COAT Z coating provides superior corrosion resistance, while the two-part floating design with aluminium brake disc hub offers reduced weight, improved heat management and enhanced durability compared to conventional single-piece discs.
