Did you know improperly maintained brake caliper pins contribute to over 20% of all brake-related accidents annually? Many of us don’t know that Brake caliper pins play a critical role in allowing the brake pads to move smoothly back and forth and squeeze the brake pads in order to brake.
So, for safety, you need to maintain brake caliper pins constantly. One essential procedure to maintain these caliper pins is to grease them. But “what grease to use on brake caliper pins?”
you will have to purchase high-temperature grease that can defy the high levels of heat and friction emitted from the brakes while braking, just like Permatex Ceramic Extreme Brake Parts Lubricant, Which is the best grease you will find for your caliper pins.
Because as we know, brakes work on friction, so they generate too much heat, and any oil grease will likely not work on them because it will make them catch fire because of the friction.
In this post, we will provide all the information on maintaining the brake caliper pins. By following that, you can make sure they last long. So keep reading!

What are brake caliper pins?
Before we start greasing brake caliper pins, we need to know first what are brake caliper pins. And how do they work?
The brake caliper guide pins are small round metal pins located on each brake caliper that help the brake pads by providing a clamping force to align with the brake disc. They are known as “guide pins” because they guide the brake pads into the correct position. A caliper needs to move freely for good brake performance. So the caliper pins attach it to the rotor and help the brake caliper to move freely.
Types of Brake Caliper Grease
1. Mineral Oil-Based Grease
Petroleum-based products are commonly used to make mineral oil-based formulas. Occasionally, additives are combined with these products to make them thicker, smoother, and better able to handle different temperatures.
However, petroleum-based grease does not perform as well as silicone and synthetic grease because it’s made of petroleum, in high temperatures, and has high torque tasks like brake calipers.
As a result, there may be better choices for use on wheel bearings. Not to mention it makes more noise than any other synthetic-based lubricant found.
2. synthetic grease
When it comes to brake caliper grease, synthetic grease is a versatile option that comes in different types with varying thicknesses, additives, and resistance to moisture and extreme temperatures.
Synthetic grease can be made using different materials, such as lithium or calcium, and may contain additives to improve its performance. Additionally, some synthetic greases are silicone-based instead of using traditional petroleum-based grease with mineral oil.
3. Silicone grease
Silicone grease is a highly versatile lubricant that is thick and has a consistent texture. It is also able to withstand extreme temperatures, making it useful in a wide range of applications.
Compared to oil-based greases, silicone grease is less likely to damage materials like rubber, metal, wood, and glass.
the best grease for brake caliper pins
You will have to use the best grease available for proper maintenance of your brake caliper pins. The best grease for caliper pins has to be waterproof silicon-based grease. So that any Water invasion won’t affect it, and it helps the caliper pins to slide without getting damaged.
Also, another important factor regarding this grease is, it has to be heat resistant. We all know that brakes work on friction, and the friction generates enough heat to spark and ignite. So the grease you will buy has to withstand heat a minimum of 400 degrees Fahrenheit, which is the average temperature of a basic car’s brake.
Also, the grease needs to have higher viscosity to withstand friction and protect the brake from getting worn out.
Another important factor is the lower temperature performance of the grease. The lower temperature shouldn’t affect the grease in any way.

How often do you need to Car’s Brake Caliper Pins?
Maintaining your car is a priority, and it must be done because your safety depends on it. Every part of a car needs maintenance, even its small brake caliper pins. We will give you instructions on how to maintain your brake caliper pins by lubricating it read along. But first, you need to know how often you need to lubricate your brake calipers.
It’s important to grease your car’s brake caliper pins every 12,000-15,000 miles or once a year to avoid wearing out your brake pads too quickly. The brake pads bear a lot of stress and often need to be replaced, but you can prevent premature wear and tear by greasing the pins.
If the pins aren’t lubricated, they can pierce through and cause the brake pads to wear unevenly or not make proper contact with the rotor. This can cause the pads to wear out faster or weaken the brake.
Greasing the pins can help avoid costly brake pad replacements, which can cost anywhere from $30 to $150 just in parts. Check your car’s user manual to see if there are any specific instructions for your vehicle.
How to apply grease on brake caliper pins (Easy 14 Steps)
The brake is a crucial and also sensitive part of the vehicle. One wrong step can cause the brake to malfunction and cause serious tragedy. So when dealing with brakes, it should be left to the professionals because they can do the job properly, and you can drive your car overthinking if you placed the pins or not.
But if you have experience in changing tires and brakes by yourself, you can give it a try. First, you will need to gather tools such as
- A car jack
- A socket wrench with a socket set
- A brake caliper tool
- Your grease product of choice
- Lint-free towels
- A wire brush
Step 1: Once you gathered everything you need, now you’ll need to lift your car off the ground with a car jack and secure it in place so you can access the tire and brake components, such as the brake caliper pins.
Step 2: Before you clean and lubricate your brake caliper pins, be careful and take your time to avoid damaging any parts.
Don’t let the bracket hang on the brake line, as this could cause the line to become strained. Instead, you should tie the rack to another part of the system to keep it secure.
Step 3: take off the rubber boot and remove each side of the pins one by one.
Step 4: now remove the rubber boot also.
Step 5: Next, look closely at the slide pin and see if there are any signs of wear or damage. If you notice any issues, it’s important to replace the pin. Additionally, check the rubber boot for any tears or damage, and replace it right away if you find any problems.
Step 6: Cleaning off any old grease is important before applying new grease to the slide pins. Mixing different types of grease can cause a bad reaction and make it less effective. So, unless you’re sure that the new grease is the same as the old one, make sure to wipe off the old grease first.
Step 8: Add some fresh grease onto the slide pin’s body and use your finger to distribute it around evenly.
Step 9: Next, you can apply some grease to a pin and insert it into the hole of the caliper. Then, rotate the pin to ensure the grease spreads evenly before removing it.
Step 10: Put the rubber boot into the hole.
Step 11: slide the pin into the rubber boot
Step 12: now repeat the same process for another slide pin
Step 13: Now, you can put the caliper back together by following the reverse steps of how you took it apart.
Step 14: Put the wheels back on, and your task is complete.
What happens if you don’t use caliper grease?
The brake pins will get misaligned with the pad. And this will cause extreme frictional heat, which can make the pad wear and tear faster. In short, the lifespan of your calipers and the entire brake system will be damaged, and you might need to change and reinstall them completely.
Is Silicone Grease Best for Brake Caliper Pins?
Yes, silicone-based grease is resistant to moisture, and as we know, caliper pins are always exposed to moisture, so silicon-based grease prevents the caliper pins from rusting.
Also, this type of grease has a higher melting point than others, which means the excessive heat that the brake produce has less effect on the caliper pins.
Besides, it works well in extremely low temperatures as well, and its thickness of it minimizes the wear down of the pads, and lastly, the high adhesive property of the grease makes the contact points stay together for a longer time, which prevents any damage to the joints.
The brakes on our vehicle are a crucial component to control the motion and also for safety. So maintaining every part of it is vital for a better driving experience and also to prevent accidents. Brake caliper pins are crucial components of a car’s braking system.
So maintain them by lubricating every 12,000-15,000 miles or once a year to ensure that you can avoid wearing out your brake pads and have good braking. But what grease to use for brake caliper pins?
After reading this post, you can guess what lubricant is best for your vehicle and how to apply them from the information we provided. Remember that smart are those who are prepared. So to prevent any wear or damage on your brake caliper pin, you should maintain them by lubricating them once a year.
