1989 Audi 90 Quattro Brake Rotors and Drums

ATE, a brand of Continental with more than 100 years of experience in brake development, is once again setting the standards in quality, innovation and system expertise. The high-carbon brake discs have a number of positive characteristics – they optimize durability and prevent, for example, brake judder and noise. With extremely low tolerances of max. 30 µm for lateral runout and max. 10 µm for thickness variation, ATE provides ideal aftermarket solutions in its role as a system supplier with OE expertise. The tolerances of the centering bores are also extremely low in order to prevent imbalance and radial runout. This contributes to extending the service life of the wheel suspension and wheel bearings. Depending on the vehicle model, mounting bolts are included with the brake discs at no extra charge. These mounting bolts are used to fix the brake disc to the wheel hub during installation. The bolt symbol on the brake disc label provides a clear indication that mounting bolts are included in the package. The mounting bolts included with ATE brake disc packages are always coated bolts, which reduces their susceptibility to corrosion and increases the longevity of the product. The MetaCote protective coating formulation is cured at approximately 572F. No grease or oil to remove. This helps protect against road salt, brake fluid and other corrosives – sheds water and dirt for clean appearance behind cast spoke wheels. Reduction in overall installation time.

Product Features:

• OE-equivalent and a direct fit replacement.
• Patented RotorLife wear indicator.
• Optimum performance at all temperatures.
• Reduced rotor wear.
• less susceptible to noise and vibration.
• MetaCote protective anti-corrosion coating.

Carquest Wearever rotors meet or exceed original equipment specifications while delivering superior stopping power. Carquest Wearever rotors are manufactured with proper harmonic design and non-directional finish that eliminate noise and enhance pedal feel. Our rotors are designed to effectively dissipate heat, helping to eliminate brake fade and increase the life of your pads and rotors. Carquest Wearever rotors are designed for long-lasting and quiet braking with superior performance.

Product Features:

• Meets or exceeds OE design for superior stopping power
• Exceeds ISO manufacturing guidelines (International Organization for Standardization)
• Matches OE vane size for proper cooling
• Optimal metallurgy and casting thickness to preventing warping
• Air gap eliminates brake fade and increases pad life
• Non-directional finish decreases break-in time
