Benefits of Brake Caliper Grease
- Proper lubrication. General-purpose grease tends to evaporate or melt off under extreme driving conditions. This is why it’s necessary to have grease that’s specifically formulated for your brake calipers, and can withstand the high temperatures that the brakes generate.
- Avoid damaging the brake components. Not just any grease is good for your brake calipers. Some greases can corrode the rubber seals or plastic bushings. Brake caliper greases, on the other hand, don’t have harsh formulations and instead preserve the integrity of the critical components by sealing out contaminants.
- Reduce brake noise. The brakes can get extremely hot during repeated braking or when hard braking. This can force the lubricants to melt and that’s when you start to get the squeaky noise. Lubricating the caliper at the point it touches the brake pad can help reduce the friction on both surfaces, and consequently reduce or eliminate the squeaking sound.
Types of Brake Caliper Grease
Mineral Oil-Based Grease
Mineral oil-based or conventional greases typically use petroleum-based products as the lubricating agent. They can be formulated with additives to meet high temperatures, extreme pressures, and any other harsh environment.
Synthetics are formulated to outperform and outlast conventional greases. They have superior lubricating capabilities across a wider temperature range and form a thicker oil film between the surfaces. They are also less prone to degradation in extreme pressure or high temperature conditions and maintain proper viscosity at low temperatures. The fact that synthetics last longer than the other alternatives means that you can extend the frequency of your regreasing schedule from monthly to quarterly.
Silicone grease is a thickened silica compound that’s formulated to provide lubrication and corrosion resistance. It’s often used to replace oil-based greases that attack rubber components. It’s used in its pure form to maintain stability under high temperatures. However, it can be easily washed out or contaminated with most organic solvents.

Brake Caliper Grease Pricing
- Under $30: The price of a brake caliper grease is mostly determined by the size and formulation. That being said, expect to find 8-ounce containers to smaller 1-ounce tubes within this price range.
- $30 to $50: As with any other car care product, spending more money could translate to improved results. This means that the greases here have better extreme temperature tolerance, are more viscous, and come with an applicator brush.
- Over $50: Budget this much for larger containers of about 20 ounces or more. You can also get the same product in the lower price range but packaged in sets of four or more, depending on the size. You can expect the formulation to be better and longer-lasting if the grease comes as a single unit.
Viscosity is used to describe the thickness of a fluid or its ability to resist flow. Greases need to have a high viscosity in order to stay put on the applied surface. This is to ensure that they protect the surface from the effects of friction for a longer time.
The grease should be able to resist melting or freezing at a wide temperature range. This ensures that it will maintain its lubricative properties despite being exposed to extreme temperature changes. Select a grease with a non-melt or non-freeze formula, and note the temperature range which it can function at.
If any part of the brake caliper were to come in contact with water, it would rust and wear out faster than usual. This is why you need a grease that effectively seals out moisture to keep the components dry and in their best working condition.
- Application: Grease can be classified according to the application. This is why we have all-purpose (AP) grease, which is suitable for all vehicle applications. Multi-purpose (MP) grease is formulated for light vehicle applications. Lastly, there's extreme pressure (EP) grease, which is more stable and durable under very intense pressure. EP grease offers more reliable protection for metal-to-metal components than the other options.
- Additives: Additives are special ingredients that are introduced in the grease while it’s being manufactured to improve its properties. They are typically included for advanced wear protection, corrosion prevention, and rust protection.
- Thickeners: The grease needs to have a thickener that helps to keep the grease particles from dispersing easily. The thickener also helps to bond the additives to the base oil. The most commonly used thickener is lithium.
Best Brake Caliper Grease Reviews & Recommendations 2020
- Be sure to apply the proper amount of lube when you're working on the brakes. Using either too much or not enough will adversely affect the effectiveness and/or lifespan of the brakes.
- Experts recommend that every time you rotate your tires you clean the grit from your brakes with an air compressor as well as add some lubricant if it’s required.
- You should replace your brake pads approximately every two to three years, depending on how quickly they wear. Calipers on modern vehicles can last as long as 10 years but should be monitored in the meantime. Using the correct lube will keep your system running efficiently for a longer period of time.
Q: How do I lubricate my brake calipers?
A: First, remove rust from the caliper brackets using a wire brush or other tool. Clean or replace hardware, and lubricate any of the metal to rubber friction points.
Q: Can I use regular grease for brakes?
A: The brakes on your car can get extremely hot, particularly when braking hard or braking repeatedly. Some general-purpose lubricants aren't designed to hold up in these types of conditions. You need high-temperature grease that can take the heat and won't damage rubber or plastic components.
Q: Can I use lithium grease on brake calipers?
A: White lithium can be used on drum brake hardware and backing plates; however, it is a low-temperature grease, so it shouldn't be used on front disc brakes.
Our pick for the best brake caliper grease is the Mission Automotive Dielectric Grease/Silicone Paste/Waterproof Marine Grease. It's waterproof and seals and protects various components, including brake caliper pins.
