2008 Audi S4 Brake Parts

The Zimmermann Sport Brake Disc was developed as a result of experience of brake discs in series-production vehicles in connection with racing. The brake system is optimized by combining high-quality cast materials with a slotted or cross-drilled braking surface. Coat-Z Protective Coating – The Zimmermann Coat-Z brake disc provides a protective coating that prevents rust and corrosion, extended rotor life and improved visual appearance. To improve the rust protection during storage and usage, Otto Zimmermann GmbH implements this new Coat-Z technology step by step in its production range. Beside the still optimum function of the brake disc, this coating ensures a consistent attractive appearance. Material quality / high carbon – Zimmermann brake discs are usually made of cast iron (with flake graphite) of different qualities; they correspond to the material used for the original spare parts. Therefore, the utilization of such materials (referred to as High Carbon by the competition) has always been a matter of course for Otto Zimmermann.

Product Features:

• Coat-Z protective anti-corrosion coating
• Better wet braking performance by permanent expulsion of brake dust and water
• Sporty look
• Because of the anti-corrosion protection Coat Z better finish – especially of the hub and the outer diameter
• Noticeable improvement in the braking power of your car
• Prevention of brake fade
• Countersinking of holes doubles up as wear indicator
• 1:1 exchange of original disc possible
• No additional adaption necessary
• Not subject to registration: general ABE certification supplied with disc

ATE Original brake pads provide quality friction just like the OE pads they replace, providing customer-pleasing brake performance. With the best mixture of materials on the market and a production process which emphasizes quality all the way through, original ATE brake pads represent the state-of-the-art. In order to prevent noise during braking, highly effective primary and secondary measures are both used on brake pads. Primary measures act directly on the point of friction. Here, the main issue is optimization of the materials used for the relevant parts. In many cases, ATE uses the most effective variant and the best primary measure for noise suppression in the industry: the intermediate layer or underlayer! On the other hand, secondary measures are intended to prevent the structure-borne sound which is produced from reaching the ear of the driver and pedestrians. Secondary measures can generally be divided into four groups: damping plates, damping foils, paints and greases. ATE works with over 150 different mixtures of friction material to ensure that the optimal result is always achieved for any particular application. The friction materials are always being refined and developed for this purpose. The pad material consists of various components which each fulfill different functions during braking

Product Features:

• OE engineered brake system technology assures optimum fit and performance
• Advanced friction vehicle specific formulations
• Reduced dusting and extend pad life
• Application matched premium quality friction grade
• Underlayer design helps reduce noise, vibration and harshness
• Shims, chamfers, slots, wear sensors and other premium features included Original ATE Brake pads – Presentation

Brakes are designed as a system and all the parts need to work together for best performance. Industry brake service experts agree – when brake friction materials are ready to be replaced, the hardware is too. A complete brake job that includes new hardware goes a long way toward preventing comebacks. Changing out your Rubber Pin Boot or Slider Bushing Kit will ensure the guide pins are clean and free from debris for smoother braking.

Product Features:

• This part matches Original Equipment (OE) quality specifications

Rein OE Manufactured Brake Vacuum Pumps are produced in an OE factory to the specifications of the auto maker’s engineers! These brake vacuum pumps come complete with a mounting gasket or seal, depending on the application. Vacuum pumps are used in vehicles with engines that do not produce sufficient vacuum to provide power to the braking system, EGR valves, intake manifold switches, as well as turbocharger actuators and others. A failed or improperly working brake vacuum pump can lead to a reduction in braking power, a reduction in part and/or full load performance, a triggering of check engine light or limp mode, or engine misfires. All Rein brake vacuum pumps are manufactured by an OE manufacturer and are the exact same units that originally came on the vehicle!

Product Features:

• Ensures the proper operation of vehicle’s braking as well as all other vacuum dependent systems
• Engineered and manufactured by an OE manufacturer
• Plug and play replacement for original vacuum pump
• Applicable gasket included

New Brake Hardware – Back to like-new performance The WBR complete disc brake hardware kits provide everything you need to perform a complete the brake job and restore the brake system back to the optimal like new operating condition. Disc hardware can lose 50% of spring tension within 1-2 years, which can cause pads to stick, create uneven pad wear, and lead to unwanted brake noise.

Product Features:

• Reduced Brake Noise, comebacks and unsatisfied customers,
• Extends the life of a brake job,
• Improved fuel mileage, and
• Restores brakes to like new Performance. Effects of Corrosion, Heat, Stress, Use Rust and Corrosion on floating caliper slides or bushings can prevent the caliper from centering properly, which can

Since 2008 Zimmermann is offering almost 400 Standard and almost 400 Sports Brake Discs in a coated version named Coat Z. The Zimmermann Coat-Z brake disc provides a protective coating that prevents rust and corrosion, extended rotor life and improved visual appearance. To improve the rust protection during storage and usage, Otto Zimmermann GmbH implements this new Coat-Z technology step by step in its production range. Beside the still optimum function of the brake disc, this coating ensures a consistent attractive appearance. Zimmermann brake discs are usually made of cast iron (with flake graphite) of different qualities; they correspond to the material used for the original spare parts. Therefore, the utilization of such materials (referred to as High Carbon by the competition) has always been a matter of course for Otto Zimmermann.

Product Features:

• Coat-Z protective anti-corrosion coating
• No formation of rust at the hub and herewith improved visual appearance
• Immediate functional capability without removal of the coating before mounting
• Excellent deceleration action and no distortion of friction ring at high temperatures
• Substantial weight saving and therefore less unsprung mass
• Floating mounting enables radial expansion of the brake disc under relatively heavy loads, thus preventing shielding and increasing resistance to heat cracks
• Hot spots prevented by optimized design of ventilation channels
• 1:1 exchange of original disc possible
• Not subject to registration: general ABE certification supplied with disc
• No conversion required for brake tuning

Brake Disc

Caliper housing spring retaining clips are an essential component of ATE-designed fist floating brake calipers. The fist floating caliper consists of a holder and housing, which is located in rubber damping sleeves. It slides within the holder together with the outer brake pad while as the pad wears. To prevent the housing from lifting off the pad and causing noise issues, the caliper is pulled against the brake pad by the caliper housing spring retaining clip. These clips are exposed to continuous corrosion attack and should therefore also be replaced each time the brake pads are changed.

Product Features:

• Premium Original Equipment replacement
• Provides performance and dependability
• Manufactured to meet OE specifications
