Now that the weather is getting nicer, more and more people are taking their bikes out for a spin. If you're one of those people, it's important to know how to properly maintain your bike brakes. One way to do that is by using mineral oil. But what is mineral oil, and what are its benefits?

Surely you've seen the commercials for mineral oil. They call it "the stuff that makes your car go." But it can be more than just a lubricant. I recently discovered this and had to share my findings. Keep reading to find out!

Uses of Mineral Oil for maintaining car brakes:


Mineral oil is a substance that is derived from petroleum. It has a variety of uses, one of which is for maintaining car brakes. When it comes to keeping your car brakes in good working order, mineral oil can help to extend their life and keep them functioning properly.

Here are some of how mineral oil can be used for maintaining car brakes:

1. Mineral oil can clean the brake pads and discs.

2. It can also be used to lubricate the caliper pins, which can help to prevent sticking and corrosion.

3. It can also lubricate the pad springs and other moving parts of the braking system.

4. It can be used on the disc pads to reduce wear and prevent corrosion.

The advantages of mineral oil include:

1. Its non-toxic nature makes it safe to use.

2. It is inexpensive and readily available.

3. It does not emit harmful toxic fumes when used for lubrication.

Here are 5 reasons it is important to use mineral oil.

1) Preventing brake fade

If you're riding in hot weather, you know how quickly your brakes start fading. The heat causes friction between the pads and the rotor.

This creates carbon buildup on the pad, which reduces braking power. Mineral oil is an excellent way to prevent brake fade. It's cheap, easy to use, and will keep your brakes working well into the fall season.

2) Keeping your brakes clean.

When you ride, dirt gets all over your hands and fingers. It also collects on your brake levers and calipers. This is where most people get their brake dust. You don't want to breathe in brake dust because it contains bacteria. So if you have brake dust, wipe it off with a rag or cotton ball dipped in a solution of water and mineral oil.

3) Cleaning your rims.

Riding on dirty rims wears them out faster. So make sure they're always clean before you hit the road. Use a damp cloth to remove grit from the surface. Then apply some mineral oil to help protect against rust.

4) Washing your chain Chain lube helps keep your chain running smoothly.

And when it does break down, it keeps the pieces apart so they won't jam up your drivetrain. To wash your chain, simply run it through a bucket of warm water. Dip a rag in mineral oil and then rub it inside the links.

5) Protecting your derailleur.

Derailleurs are expensive components. So it's important to take care of them. One of the best things you can do is add mineral oil to the grease in your derailleur.

Can I use mineral oil instead of brake fluid?

It's important to use the right brake fluid on your bike. Brake fluid is used to stop the motion of the brake pads against the disc rotor. If you don't use the correct fluid, your brakes won't work as well as they should.

Brake fluid must have a high boiling point, be incompressible, and withstand high temperatures to do its job correctly. That's why most people use brake fluid in their bike brakes.

However, some people choose to use mineral oil instead of brake fluid. Mineral oil has a lower boiling point than brake fluid, so it may not be suitable for all types of bikes. Additionally, if you use mineral oil instead of brake fluid, you will need to regularly top up your system with more mineral oil. This will keep your brakes working correctly.[1]

Is mineral brake oil corrosive?

Mineral brake fluid is a type of brake fluid that is designed to work in high-temperature environments. This type of brake fluid is often used in hydraulic braking systems. One common question about mineral brake oil is whether it is corrosive.

The answer to this question depends on your specific type of mineral brake oil. Some mineral brake oils are more corrosive than others. It is important to read the label on the bottle to find out how corrosive the particular brand of mineral brake oil is.

If you are concerned about the potential for corrosion, you can take steps to protect your bike's brakes from damage. One way to do this is by using a sealant or lubricant on the fittings and hoses in your braking system.

Can I use any mineral oil for hydraulic brakes?

No, using a different mineral oil instead of hydraulic fluid can damage the rubber seals inside the braking system, leading to malfunctioning brakes. Always use the brake fluid authorized by the brand.

Additionally, use only the bleed tools and parts authorized by the brand. Original hoses and hose fittings are just as crucial as the correct fluid. If they're not compatible, it could lead to decreased performance or even unsafe braking.

Mineral oil brake fluid is corrosive, isn't it?

There has been some debate about the corrosiveness of mineral oil brake fluid. Some people claim that it is more corrosive than DOT fluid and can damage paintwork. Others maintain that it is less harmful and more effective.

What's important to remember is that both brake fluid types are hygroscopic, meaning they absorb water.

This means that if you're using DOT fluid, you need to be careful not to let any moisture get into the bottl3, This will decrease the boiling point and could lead to brake failure.

A mineral oil brake fluid is a type of DOT fluid that does not pool in one place, making it less likely to cause corrosion. It's also less expensive than regular DOT fluid and available from various sources.

Can you mix different brands of mineral oil?

There is no clear answer as to whether or not you can mix different brands of mineral oil. Some brands of mineral oil are incompatible, and using them together in hydraulic brakes can cause problems.

Shimano does not recommend using any other brand of mineral oil in their brakes, as it could damage the seals and lead to premature brake failure.

However, Miles from Juice Lubes has confirmed that their Mineral Oil is compatible with a range of brake manufacturers, and they have never reported any problems with their products.

The manufacturers of mineral oil have a vested interest in recommending their product only, but Juice Lubes tests their products and ensures they are of the highest quality.

What is the difference between mineral oil and brake fluid?

The main difference between mineral oil and DOT fluid is that mineral oil is non-corrosive, whereas DOT fluid is corrosive. Both fluids perform the same function, but there are differences in how they work.

For example, mineral oil is thicker than DOT fluid, which makes it easier to apply to the pads and pistons. However, it's harder to clean up after applying it and more difficult to find.

DOT fluid is thinner than mineral oil, which allows it to flow better through the lines and channels of the braking system. It's also easier to clean up when applied and evaporates faster than mineral oil.
