Benefits of Brake Caliper Grease
- Lubrication. Properly lubricated brake parts simply work better. Your caliper and wheel cylinder assembly is a complex series of internally moving parts, including but not limited to pins, bushings, and caliper slides. All of these mechanisms need to be lubricated to keep the pads sliding optimally within the caliper housing.
- Vibration and noise reduction. Brake caliper grease helps limit vibrations and noise generated by caliper pistons and disc brake pads. repeated and hard braking can create excess friction, resulting in squealing noises over time. By lubricating the caliper at the point of brake pad contact, these two symptoms can be eliminated.
Types of Brake Caliper Grease
Mineral Oil-Based Grease
Petroleum-based products underpin mineral oil-based formulas. it may or may not be mixed with additives to achieve better viscosity, consistency, and working temperatures. Generally, petroleum-based brake caliper grease performs worse with high temperature, high torque applications. Because of this, it is not as safe on wheel bearings as silicone and synthetic grease.
Note: mineral oil-based grease also runs louder than standard/synthetic greases with high-speed applications.
Consider synthetic grease the wild card of brake caliper grease. Synthetic greases offer a variety of different formulations with more or less viscosity, additives, moisture resistance, and extreme working temperature ranges. For example, some synthetic grease formulas use lithium or calcium along with additives to enhance working temperatures.
Many synthetic greases are also silicone-based, as opposed to conventional petroleum-based grease with mineral oil.
Silicone grease is a jack of all trades, known for its thick viscosity, consistency, and extreme working temperature range. Unlike oil-based greases, it is safer on more brake materials such as rubber, metal, wood, and glass.

Brake Caliper Grease Pricing
- Under $30. Brake caliper grease under $30 falls into the bargain basement category. These are typically categorized by size. Expect mineral oil-based grease over silicone/synthetic grease with a container size no larger than 8 ounces.
- $30 to $50. This price range offers improved extreme working temperatures, higher viscosity, and silicone/synthetic grease over weaker mineral oil-based grease. Note that mineral oil-based grease (comprising petroleum-based agents with additives) works poorly for rubber components and is more easily washed off, hence the premium paid for silicone and synthetic grease.
- $50 and up. Brake caliper grease formulas in this price range typically have an increased container size. Expect 20 ounces or greater containers with the same formulation as formulas priced from $30 to $50.
Here are some of the more important features to consider when looking for brake caliper grease.
Viscosity refers to thickness. The higher the viscosity, the greater the friction protection, as it produces more stickiness that keeps the formula on your lubricated parts over time. This concept applies to any component, whether it be O-rings, calipers, disk brake pads, or self-adjusters.
The best brake caliper grease holds extreme operating temperatures due to the excess heat generated by friction between calipers and brake pads metal-on-metal contact. Some lesser brake caliper grease formulas break down in heat. Our recommendation is to go with silicone and PFPE-type brake caliper grease formulas that can withstand temperatures between -40 and 392 degrees Fahrenheit. Polyglycol follows, working well in temperatures between -40 and 257 degrees Fahrenheit. Avoid PAOIs and ester-based formulas.
Pay close attention to a brake caliper grease certification. Some formulas are classified as all-purpose (AP) grease and other formulas are classified as multi-purpose grease. The difference between both lies in their stability and durability under immense pressure, with all-purpose grease holding higher operating temperatures, greater viscosity, and all-around better performance than the lighter-duty multi-purpose grease.
Note, some ingredients found in brake caliper grease formulas may not be compatible with your brake pad. For example, PAO and ester-based lubricants are known to attack plastics, whereas silicone and PFPE-formulas work better with plastic. When in doubt, opt for silicone-based brake caliper grease.
Many brake caliper grease formulas come with brushes. Look carefully and see if it's a bent versus a straight brush. Some users prefer one over the other based on how comfortable they feel during the application process.
Look at water resistance very carefully. Waterproof lubricants are better able to keep moisture out, preventing rust and corrosion.
Best Brake Caliper Greases Reviews & Recommendations 2021
- 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.
- Opt for silicone-based brake caliper grease over other formulas. Silicone grease offers outstanding viscosity and keeps plastic and elastic parts safe, unlike hydrocarbon-based oils. It holds the highest temperature resistance (high-temperature resistance (-40 to +500 degrees Fahrenheit) of all types.
- Upon every tire rotation, use an air compressor to clear brake dust and debris off of your brakes. This makes lubricant easier to apply and creates additional stickiness.
- Keep brake caliper grease stored in a cool and dry location with temperatures ranging between 46 to 82 degrees Fahrenheit for the best results.
- Watch out for synthetic formulas. Some synthetic formulas do not work well with rubber boosts and bushings.
- Avoid low viscosity formulas. Low viscosity formulas can drip or run, loosening off of your brake parts and generating wear and tear over time.
- Watch your driving conditions. If driving in colder climates, opt for lubricating your brake caliper pins at least quarterly or depending on driving conditions. If not, expect faster wear and tear on your brakes due to increased friction between your rotor and brake pads. Any excess corrosion is a surefire sign your brake caliper pins need to be lubricated or replaced.
- Look for brake caliper grease with an extreme working temperature range (e.g. -40 to +500 degrees Fahrenheit). Lower quality brake caliper grease will cause your components to dry out or lubricate to freeze or melt. Watch for non-freeze and non-melt formulas.
Q: How do I lubricate my brake calipers?
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?
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?
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.
Q: What grease do you use on brake calipers?
Our recommendations on the best brake calipers run the gamut in terms of price point, consistency, noise/vibration reduction, operating range, and compatible connections to rubber, plastic, and metal. Our top recommendation is the Mission Automotive Dielectric Grease/Silicone Paste/Waterproof Marine Grease, an excellent choice for brake caliper pins, O-rings, rubber gaskets, and steering bushings with the included brush, silicone base, and safe use across all different types of brake material, including metal, rubber, and plastic.
Q: What happens if you don't grease caliper pins?
Not greasing caliper pins could result in sustained wear and tear over time, causing uneven brake pad wear, poor brake-to-rotor contact, and sticking slide pins that cause excessive heat buildup. Excess brake dust buildup can also result.
We highly recommend lubricating your caliper slide pins at least twice a year or as needed based on driving conditions. Colder climate drivers may benefit more for more frequent lubrication
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.
