TL;DR
- Brake grease helps parts slide freely, stops rust, and cuts brake noise.
- Use silicone-based brake grease on caliper slide pins and anything touching rubber boots; never petroleum grease, which can damage the boots (Rick's Free Auto Repair Advice, 2026).
- Never use anti-seize on caliper slide pins, because it is not a lubricant (Rick's Free Auto Repair Advice, 2026).
- Use a thin film of high-temperature synthetic, ceramic or moly grease on pad contact points, the piston face and the caliper fingers (Rick's Free Auto Repair Advice, 2026).
- Keep all grease off the pad friction material and the rotor face, and use less rather than more (EngineerFix, 2026).

What Is Brake Grease?
Brake grease is a high-temperature lubricant made for brake parts. Normal grease melts, dries out or swells rubber when it gets hot, so it cannot be used on brakes.
Brake grease does three jobs. It lets the caliper and pads slide freely so the pads release from the rotor, it protects metal from rust, and it damps the vibrations that cause squeal (Rick's Free Auto Repair Advice, 2026).
A good comparison is oil on a door hinge. The right amount in the right place keeps it moving quietly; the wrong product or too much makes a mess.
The Main Types of Brake Grease
| Type | Best for | Notes |
|---|---|---|
| Silicone-based | Caliper slide pins, rubber boots, abutment clips | Safe for rubber; dielectric, so it resists corrosion |
| Synthetic or ceramic | Pad ears, backing plates, caliper fingers, piston face | High heat resistance; reduces noise |
| Molybdenum (moly) paste | Metal-to-metal contact points | Not for rubber parts |
| Anti-seize | Bolt threads only | Never on slide pins |

Where to Apply Brake Grease
Apply a thin film of the right grease to these points:
- Caliper slide pins: clean off the old grease, check the boots, then apply fresh silicone brake grease (Rick's Free Auto Repair Advice, 2026).
- Under the abutment clips: clean the rust off the caliper bracket and apply a light film of silicone grease before fitting the clips. This helps stop rust building up under the clips (Rick's Free Auto Repair Advice, 2026).
- Pad ears: a very thin film where the pad ends slide in the clips.
- Back of the pad: a thin film where the backing plate or shim touches the piston and caliper fingers (Rick's Free Auto Repair Advice, 2026).
- Loose shims: if the noise shims are not permanently attached, lightly grease the backing plate before fitting the shim (Rick's Free Auto Repair Advice, 2026).
The Lisle 13410 brush makes the cleaning step quick, and a new hardware kit replaces worn clips.
Where Never to Put Brake Grease
- The friction surface of the brake pads.
- The rotor braking surface.
- The inside of the caliper piston bore (this uses brake fluid or assembly lube, not grease).
- ABS sensor rings or wheel speed sensors.
If grease touches a pad's friction surface, the pad may not grip properly and should be replaced. Clean the rotor with brake cleaner if grease touches it.
Grease vs Anti-Seize on Brakes
Anti-seize and brake grease are different products. Anti-seize protects threads from seizing; it is not a lubricant for sliding parts. Using anti-seize on slide pins is a common mistake and should be avoided (Rick's Free Auto Repair Advice, 2026).
Anti-seize has a place on some bolt threads and hub faces, as covered in our Loctite C5-A review, but keep it off slide pins, pads and rotor faces.
How Much Brake Grease to Use
Use a thin, even film. Too much grease is a common mistake, especially on slide pins (EngineerFix, 2026). Extra grease can trap air in the pin bore, attract dirt and spread onto the pads.
Some mechanics find that thick ceramic-type greases can dry and cake over time, which is another reason to keep the layer thin and use silicone on the pins (Bob Is The Oil Guy forum, 2026).
Common Brake Grease Mistakes
| Mistake | Result | Fix |
|---|---|---|
| Petroleum grease on slide pins | Swollen boots and sticking pins | Use silicone brake grease |
| Anti-seize on slide pins | Pins can stick once the carrier dries | Use proper brake grease |
| Grease on pad friction surface | Weak, uneven braking | Replace the contaminated pads |
| Too much grease | Dirt build-up, mess on pads | Apply a thin film only |
| Skipping the clean-up | Rust lifts the clips and binds pads | Clean abutments to bare metal first |
Frequently Asked Questions About Brake Grease
What grease should I use on caliper slide pins?
Silicone-based brake grease, which is safe for rubber boots (Rick's Free Auto Repair Advice, 2026).
Can I use regular grease on brakes?
No. Petroleum grease can damage rubber boots and cannot handle brake heat (Rick's Free Auto Repair Advice, 2026).
Can I use anti-seize on slide pins?
No. Anti-seize is not a lubricant and should never be used on slide pins (Rick's Free Auto Repair Advice, 2026).
Where should I put grease on brake pads?
Only on the pad ears and the back of the pad where it touches the piston and caliper, never on the friction surface.
Does brake grease stop squealing?
It can. A thin film on pad contact points damps the vibrations that cause squeal (Rick's Free Auto Repair Advice, 2026).
How much brake grease should I use?
A thin, even film. Too much is a common mistake (EngineerFix, 2026).
Summary: Using Brake Grease the Right Way
- Use silicone grease on slide pins and anything touching rubber.
- Use high-temperature synthetic or ceramic grease on metal contact points.
- Never use anti-seize on slide pins or grease on friction surfaces.
- Clean first, then apply a thin film only.
