Product Information
Full details
Permatex Ultra Disc Brake Caliper Lubricant is an essential maintenance solution for automotive DIY enthusiasts and professional mechanics who want to ensure smooth, quiet, and reliable braking performance. This high-performance synthetic lubricant excels at preventing seizing and disc brake squeal by protecting critical metal-to-metal contact points under extreme conditions, though it is supplied in a small 0.5 oz package that is best suited for targeted maintenance tasks rather than high-volume shop use.

FAQs
Can I use this on the brake pad friction surface?
Absolutely not. The lubricant must never come into contact with the face of the brake pad or the rotor as it will drastically reduce stopping power.
Does this lubricant melt in hot weather?
No, it is a non-melting synthetic formula designed to stay in place up to 400F.
How much should I apply?
Apply a thin, uniform film. Excess lubricant can attract dirt and debris, which may cause premature wear.
Is this product safe for plastic or rubber bushings?
This lubricant is specifically designed for metal-to-metal contact areas; check your vehicle's service manual regarding compatibility with specific rubber seals.
What is the shelf life of this lubricant?
If kept sealed and stored in a moderate environment, the synthetic properties will remain stable for a significant period.
Troubleshooting
Brakes still squealing after application
Ensure that the brake hardware was cleaned of all debris prior to application and verify that the lubricant was applied to the contact points of the pad, not the rotor friction surface.
Calipers still feel sticky
Check for physical damage or deep pitting on the caliper pins; if the metal itself is damaged, lubrication alone will not fix the movement issue and the parts may need replacement.
Pros and Cons

- Resistant to high heat and non-melting
- Prevents seized calipers and stuck hardware
- Effectively stops annoying brake squeal

Setup, Compatibility & Care
To use this product, thoroughly clean the metal surfaces with a brake cleaner to remove old grease, rust, or road debris before application. Use a small brush or a gloved finger to apply a thin film to the necessary contact points. Ensure the lubricant does not touch the friction surface of the brake pads or rotors, as this will severely compromise braking ability. Store the product in a cool, dry place and ensure the cap is tightly sealed after use to prevent contamination. It is compatible with standard automotive brake hardware including steel and brass bushings.
