Permatex Ceramic Brake Parts Lubricant 8 oz — High‑Temp, Noise‑Reducing Grease

This compact 8 oz. tube delivers a purple, non‑melting formula that combines synthetic carriers with real ceramic solids to stay in place and maintain lubrication where brakes generate heat, moisture and contaminants. Designed for disc brake calipers, pistons, sleeves and rubber hardware, it resists washout, prevents seizing and continues to perform from -65°F to 3000°F. The product is formulated to be compatible with common brake rubbers and plastics, helping ensure reliable operation without swelling or deterioration of compatible components.

How does this lubricant reduce brake squeal and chatter?

The ceramic solids and high‑temperature synthetic base form a stable, adherent film that dampens vibration and isolates metal‑to‑metal contact points that commonly cause noise. Because it stays in place under heat and resists washout, the lubricant preserves that film longer than many conventional greases.

• Real ceramic particles absorb and damp vibration at contact surfaces
• Heat‑stable carrier prevents breakdown during heavy braking
• Non‑melting purple formula maintains film thickness under extreme heat
• Resists moisture so noise‑reducing layer isn't washed away

Where should I apply Permatex Ceramic Extreme in my brake system?

Apply sparingly to sliding and rolling contact points where metal or rubber parts move relative to one another; avoid contamination of friction surfaces. Typical application areas include caliper pins, piston skirts, rubber boots, abutment clips and contact points on pad backing plates where noise or corrosion is likely.

• Disc brake caliper guide pins and slides
• Piston skirts and sealing surfaces (external application only)
• Rubber sleeves, seals and ethylene‑propylene components—compatibility specified
• Pad backing plate contact points and abutments to reduce wear and noise

What temperature and environmental conditions can it withstand?

This formula is engineered to function across a very wide temperature band and in challenging environments where moisture, road salts and contaminants are present. It is rated to perform from extremely low temperatures up to very high brake‑generated heat without melting or breaking down.

• Operates from -65°F to 3000°F for exceptional thermal resilience
• Resistant to moisture, corrosion and common contaminants
• Will not easily wash out in wet conditions or during heavy exposure to road spray
• Longer lasting than many standard caliper greases and disc brake quiet products

Is this lubricant safe to use with brake rubbers and plastics?

Permatex specifies compatibility with common internal and external brake rubbers and plastics, including ethylene‑propylene rubber; the formula is designed to avoid swelling or degrading specified materials. As with any brake service, apply only where recommended and keep lubricant off friction surfaces and sensors.

• Compatible with many brake hardware rubbers and plastics
• Formulated to avoid seal swelling when used as directed
• Not intended for use on friction surfaces or ABS sensor faces
• Follow vehicle manufacturer guidelines for application points and amounts

Who is this for: Permatex Ceramic Extreme Brake Parts Lubricant suits professional mechanics, DIY enthusiasts and fleet technicians who need a durable, high‑temperature grease for disc brake hardware. It’s useful when solving persistent brake noise, preventing seizing of caliper hardware, or upgrading maintenance practices on performance and heavy‑duty vehicles where long‑lasting, moisture‑resistant lubrication is required.
