Imagine you’re walking out one day to find that your motorcycle has a leaking fluid. It turns out that it is brake fluid, not engine oil. This is bad. Are you able to fix this problem right away?

My motorcycle is leaking brake fluid. If you notice that your motorcycle is leaking brake fluid, it’s likely coming from a faulty hose, loose bleed caps on the bottom of the front calipers, from an old/corroded master cylinder, or from an old/corroded brake fluid reservoir.

Leaking brakes pose a danger to you and others on the road. If the leak persists, the fluid level in your brakes will continue to fall until you lose stopping power. Your braking system works only if hydraulic fluid is present. The system’s effectiveness will decrease if the fluid level is reduced below a certain point. Your brakes’ effectiveness can be affected by leaks that introduce air into the lines.

Your Motorcycle’s Leaking Brake Fluid

It is important to remember that your motorcycle’s brake system is a closed system meaning that fluid never leaves. It gets used again and again until it’s time to change out the fluid. Even if your motorcycle doesn’t show visible leaks, you should be concerned if your brake fluid level drops.

Your brake fluid level may be low if there is any fluid leaking out or if your brake pad wears down. To compensate for excess pad travel, your fluid level will appear lower. Your brake pads should be fine. It is worth taking a look at the situation to determine what the cause might be.

If your bike has a leaky brake fluid, what can it be? There are many possible causes. This question is difficult to answer without inspecting the bike thoroughly. Most likely, a motorcycle will leak at the bleed caps or brake lines.

The fluid is carried to the piston by the brake lines. These lines can be exposed to harsh environments and can sometimes become brittle. You can try to find fluid in the hose to determine the source. It is important to immediately replace any leaking hoses.

The bottom of the front calipers houses your bleed caps. These small caps can be used to drain any fluid from the system. These can sometimes become too loose, allowing fluids to escape. Check this area for oily residues.

The motorcycle master cylinder is another possible place for a leak. This is a difficult location to locate as fluid can run down entire motorcycles, causing brake lines and other components to fail.

This can make it very easy to misdiagnose your braking system and replace a component that actually isn’t leaking. Your master cylinder can leak if it goes bad. You can clean the area around the master-cylinder and any other parts that may have brake fluid to check for leaking.

You can also find brake fluid leakage in the reservoir. These can leak and are usually made from inexpensive plastics. These can be replaced easily and cheaply if they start to leak. Make sure you prime your brake system afterward.

How to fix brake fluid leaks

Most brake fluid leaks are easy to repair. The most frustrating thing is the actual finding of the leak. You need to be scientific and methodical when you discover that your motorcycle has a leak in its brake fluid.

Oftentimes we trust too much in online forums and just because an individual online says that a certain part on a certain bike is almost always the cause of a leak does not necessary mean that that’s the cause in your case. It is crucial that you find the source of any leak before replacing any parts. This will help you save time and money down the line.

Next, clean everything thoroughly. You can find the leak much quicker if you clean everything. If brake fluid drips from the top, it can make it difficult to identify the source of the leak and whether there are multiple leaks.

Once everything is clean, you can start looking at the system from the top. You may have to pull the brakes depending on the severity of the leak to increase pressure. This will help you find the leak.

Any component found to be leaky should be replaced immediately. These are usually fairly simple to replace or remove. Air will be introduced to the system by opening the brake system. This air must be removed after the system has been shut down again.

Safety tips to consider when handling brake fluid

It is important to know how to properly use brake fluid when working on your bike’s braking system. First, remember that brake fluid must be replaced every three months. Extremely Corrosive. Brake fluid is very hard on any material. It can strip paints completely and eat up plastics.

This corrosive fluid is not suitable for brake components. This fluid is not intended to be used on any other parts of your motorcycle. It is crucial that brake fluid not get on any other items than it should be.

Brake fluid can also be very toxic. Avoid contact with your skin or eyes. The brake fluid may not cause severe skin or eye injury, but it can cause redness and irritation. When handling brake fluid, always use gloves and protection of the eyes.

If brake fluid is swallowed, it becomes even more hazardous. You should immediately contact poison control centers if you accidentally swallow brake fluid. Breathing in brake fluid can lead to death. It can also cause irreversible damage to your liver or kidneys. It is important to get medical attention immediately in order to minimize the negative effects. It is important to keep brake fluid out of reach of children and pets.

Are you required to bleed the brakes after fixing a leak?

If your brakes leak or you replace a part of your braking system, the air will get into your system. This could be very dangerous. Fluid mechanics, the study of forces, effects, and fluid mechanics, states that liquids are not compressible.

Even a tiny fraction of the pressure needed to compress liquid is too great to ignore. Gases on the contrary, however, can be compressed very quickly. This is evident when you inflate your tires.

When you have a mixture of brake fluid and air in your tires, you now have one fluid that will compress and one fluid that won’t compress. By pulling on the brake lever, you can compress the air bubbles and not move the slave cylinder.

Air in the lines will have a major impact on the effects. As a fraction of the pressure used to compress the air, a small amount will limit the movement of a slave cylinder. Slave cylinders may stop moving if too much air is present in the system.

This is why it’s important you bleed your motorcycle’s brakes after fixing a leak. A bleeder valve is located near the bottom of your brake calipers. Connect a small section of the bleeder valve hose to a bucket or bottle. The bleeder valve should be opened about half turn.

You’ll see a small amount of brake fluid and air leave the system. Now close the bleed valve. This process must be repeated until the brake fluid is completely drained from the bleeder valve..

Your system is complete when there are no more air bubbles.  Be sure to check the fluid reservoir when you are bleeding the brakes. If the fluid level drops too low, the system can start to absorb air and force you to restart the entire thing.
