3.0 Carbon Ceramic Material Brake System (CCM) -
If Equipped
The Viper is known for having world class brakes. The 2016 Viper ACR
takes this incredible braking system to the next level with the Brembo
Carbon Ceramic Material brake system. This brake system significantly
reduces the rotating un-sprung mass while increasing on-track fade
performance and long term durability.
CAUTION: These rotors may also produce some additional brake noise
due to the high performance brake pads and two-piece construction.
It is normal for the brakes to make some popping or creaking noises as
they cool down. This is the result of the two-piece construction.
Although the CCM brake rotors are a two-piece construction, they
should be replaced as a complete assembly.
CAUTION:
During brake pad replacement, install new wear indicator
sensors on the new pads (included in Mopar pad kit).
