Copper Grease vs Ceramic Grease: Choosing the Right Brake Lubricant

Prefer to listen than read? Check out our TikTok summarising this blog.

Choosing the correct brake lubricant is a small decision that can have a big impact on braking performance, component longevity and workshop efficiency. Two of the most used options are copper grease and ceramic grease, but they are not interchangeable.  

This guide breaks down the differences between copper grease and ceramic grease, explains where each should (and shouldn’t) be used and helps technicians make an informed choice for modern braking systems.  

What Is Copper Grease?  

Copper grease (also known as copper anti-seize) is a metallic-based lubricant containing fine copper particles suspended in grease. It has been a workshop staple for decades.  

Key properties of copper grease  

● High temperature resistance  

● Excellent anti-seize performance  

● Strong protection against corrosion  

● Electrically conductive  

Common uses  

● Wheel hub faces  

● Bolts, studs and fasteners  

● Exhaust fittings  

● Older braking systems  

Copper grease is particularly effective at preventing components from seizing together, especially in high-heat environments.  

What Is Ceramic Grease?  

Ceramic grease is a non-metallic lubricant formulated with ceramic particles. 

Key properties of ceramic grease  

● Extremely high temperature tolerance  

● Non-conductive  

● Non-metallic and sensor-safe  

● Resistant to corrosion  

Common uses  

● Brake pads (back of)  

● Caliper slides and guide pins  

● Areas near ABS sensors  

● Modern braking systems  

Ceramic grease is designed to reduce brake noise, prevent sticking and remain stable under repeated braking.
