• Complete Kit

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.

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

• 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

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
• reduce effective braking force
• cause uneven pad wear, and brake noise. Rubber Bushings lose there resiliency and become flattened from the torque of the braking system which can
• cause excessive caliper movement
• cause unwanted noise like rattles and thumps.
