Brake Caliper Lubricant extends brake life by properly lubricating all components and preventing breakdowns caused by brake dust buildup, squeaking, and heavy wear.
Brake caliper lubricants have different characteristics such as viscosity, noise and vibration reduction, service life, and compatibility with rubber, plastic, and metal.

Silicone Brake Grease | 2022 Products Overview
Advantages of Brake Caliper Grease
Lubricants. Properly lubricated brake components work better. Calipers and wheel cylinders are a complex series of internal moving parts, including but not limited to caliper pins, bushings, and slides. All of these mechanisms must be lubricated for optimal sliding of the pads within the caliper housing.
Reduction of Vibration and Noise Brake caliper grease is effective in reducing vibration and noise generated by the caliper pistons and disc brake pads. Repeated hard braking can cause excessive friction and, over time, squeal. Lubricating the area where the caliper makes contact with the brake pads can eliminate these symptoms.
Types of Grease for Brake Calipers
Mineral oil-based grease
Petroleum-based products are the base for mineral oil-based formulations. They may or may not be mixed with additives to improve viscosity, consistency, and working temperature. In general, petroleum-based brake caliper greases perform poorly in high-temperature, high-torque applications. As a result, they are less safe for wheel bearings than silicone or synthetic greases.
Note: Mineral oil-based greases are noisier than standard/synthetic greases in high-speed applications.
Think of synthetic grease as the wild card in brake caliper grease. Synthetic greases come in a variety of formulations with different viscosities, additives, moisture resistance, and extreme operating temperature ranges. For example, some synthetic greases use lithium, calcium, or additives to improve working temperatures.
Many synthetic greases are also silicone-based, unlike conventional petroleum- or mineral oil-based greases.
Silicone grease is a highly versatile grease known for its high viscosity, consistency, and extremely wide operating temperature range. Unlike oil-based greases, it is safe for rubber, metal, wood, glass, and other braking materials.
Brake Caliper Grease Price
Under $30.00. Brake caliper grease under $30.00 is in the low price category. They are generally classified by size. Expect mineral oil-based grease, not synthetic or silicone-based grease, in containers of 250 ml or less.
$30 to $50 This price range provides improved extreme working temperatures, high viscosity, and synthetic/silicone grease compared to weaker mineral oil-based greases.
Note that mineral oil-based greases (composed of petroleum-based chemicals and additives) are less effective on rubber parts and wash out more easily, while silicone and synthetic greases are more expensive.
50 and up Brake caliper greases in this price range generally have larger container sizes; expect 20 oz. or larger containers with the same formulation as products in the $30 to $50 price range.
Key Features To Consider while choosing the Silicone Brake Grease
Here are some important features to look for when searching for brake caliper grease.
Viscosity refers to thickness. The higher the viscosity, the greater the protection against friction and the adhesive force that keeps the compound on the lubricated parts for a longer period of time. This concept applies to all parts, including O-rings, calipers, disc brake pads, and automatic adjusters.
The best caliper greases can withstand extreme operating temperatures due to the excessive heat generated by the friction caused by metal-to-metal contact between calipers and brake pads. Some lower quality brake caliper greases can break down under heat. We recommend caliper greases made of silicone and PFPE, which can withstand temperatures from -40 to 392°C (-40 to 392°F). Polyglycerol follows suit, effective at temperatures from -40 to 257 degrees Fahrenheit; avoid PAOIs and ester-based formulations.
Please note the certification of brake caliper grease. There are two types of grease formulations, which are classified as all-purpose grease (AP grease) and multi-purpose grease. The difference between the two lies in stability and durability against large pressures. All-purpose grease has a higher operating temperature, higher viscosity, and better overall performance than lightweight multipurpose grease.
Please note that some components of brake caliper grease may not be compatible with your brake pads. For example, PAO and ester-based lubricants are known to attack plastics, while silicone and PFPE-based formulations are compatible with plastics. If in doubt, choose a silicone-based brake caliper grease.
Many brake caliper greases come with brushes. Look carefully to see if it is an angled brush or a straight brush. Some users choose one over the other because of comfort during application.
Look carefully at the waterproof performance. Waterproof lubricants tend to keep out moisture, thus preventing rust and corrosion.

Frequently Asked Questions
Q: How do I lubricate brake calipers?
First, remove rust from the caliper bracket with a wire brush or similar tool. Clean or replace hardware and lubricate all friction points between metal and rubber.
Q: Can I use regular brake grease?
A: No. Car brakes can get very hot, especially when braking hard or repeatedly. Some general-purpose lubricants are not designed to withstand these conditions. You need a high-temperature grease that can withstand the heat and not damage rubber or plastic parts.
Q: Can I use lithium grease on brake calipers?
A: No. White lithium can be used for drum brake fittings and backing plates, but it is a low-temperature grease and should not be used for front disc brakes.
Q: What grease should I use for brake calipers?
The best brake calipers we recommend vary in price, consistency, noise and vibration reduction, operating range, and compatibility with rubber, plastic, and metal. The best recommendation is Mission Automotive’s dielectric grease/silicone paste/waterproof marine grease, which is ideal for brake caliper pins, O-rings, rubber seals, steering rings, and all types of brake materials including attached brushes, silicone base, metal, rubber, and plastic It can be used safely.
Q: What happens if I don’t grease the caliper pins?
If caliper pins are not greased, they can become worn over time, causing uneven wear of brake pads, poor contact between brakes and rotors, and excessive heat generation due to sticking of sliding pins. Excessive brake dust can also build up.
It is strongly recommended that caliper sliding pins be lubricated at least twice a year or depending on driving conditions. Drivers who drive in cold weather may benefit from more frequent lubrication.
The best brake caliper grease we chose was Mission Automotive’s dielectric/silicone paste/waterproof marine grease. It is waterproof and seals and protects various components such as brake caliper pins.
