Sold as a pair.

Since 2008 Zimmermann is offering almost 400 Standard and almost 400 Sports Brake Discs.

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.

Features and Benefits:

• 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.
