Product Information
Full details
Liqui Moly Brake Anti-Squeal is a high-performance synthetic lubricant engineered for automotive technicians and DIY mechanics who need a reliable solution to eliminate brake noise and prevent component seizure. Its primary benefit is the combination of extreme thermal stability and high resistance to road salt and moisture, ensuring long-term protection for critical brake contact points. A critical caveat for users is that the product must never be applied to the actual friction surfaces of brake pads or discs, as this will severely compromise braking performance.

Extended Product Information
FAQs
Can I use this on the surface of my brake pads?
No. Never apply this product to the friction surfaces of the lining or the brake disc, as it will cause a loss of friction and dangerous braking performance.
Is this safe for ABS sensors?
This product is designed for mechanical contact points. Avoid spraying directly onto electronic sensors.
Does it prevent my wheels from rusting to the hub?
Yes, it acts as a separating paste, preventing the seizing or rust-freezing of rims on wheel hubs.
What is the operating temperature of the product?
It maintains its protective properties within a range of -40 °C to +1,200 °C.
Can I use it on drum brakes?
Yes, it is suitable for drum brake contact points and mechanical components within the assembly.
Do I need to clean the surface first?
Yes, thorough cleaning of sliding surfaces and channels is mandatory for the lubricant to function effectively.
Troubleshooting
Brakes still squeal after application
Verify that the brake pads are not worn out and that the contact points were cleaned of all previous debris before application.
Product is dripping or running
You may have applied too much; use a light, thin layer as the product is highly adhesive and does not require thick coverage.
Spray nozzle is clogged
Invert the can and spray briefly to clear the valve, or wipe the tip with a clean cloth.
Pros and Cons
Pros
- Excellent resistance to washout from salt and water
- Prevents seized components and rusted rims
- Effective across a massive temperature gradient
- Easy to apply via spray formulation
- Improves overall safety and performance of the braking system
Cons
- Risk of braking failure if applied to friction surfaces
- Requires thorough cleaning of old debris before application
- Not intended for use as a primary brake fluid or cleaner
Setup, Compatibility & Care
To ensure maximum effectiveness, the surfaces to be treated must be mechanically clean. Use a brake cleaner or wire brush to remove rust, brake dust, and old grease from sliding surfaces and channels before applying the anti-squeal spray. Shake the container well before use. Spray a thin, even coat onto the desired areas, being careful to avoid any contact with the friction material of the pads or the rotor surface. If accidental overspray occurs on the friction surfaces, clean it immediately with a high-quality brake cleaner. Store the canister in a cool, dry place, keeping the nozzle clear of buildup for future use.
