• 70% to 85%

• 10% to 25%

What is the main advantage of ceramic brake pads?

• They offer the highest dynamic friction coefficient

• They are the cheapest option

• They produce minimal noise and dust

• They are the most durable in cold climates

What is the cost range of carbon ceramic brake pads?

• More than $15,000

• Up to $1,000
