Every vehicle that will be used should first be checked regarding its brakes. A vehicle without disc brakes can actually endanger its rider. Currently, many cars are starting to use a hydraulic braking system. This brake system utilizes brake fluid.

The challenge of using hydraulic brakes is a leaking master cylinder. If a leak occurs, it can be assured that the brake performance will decrease. Therefore, checking the master cylinder should be done regularly. If a leak occurs, it should be replaced with a new one so that its function can work properly.

Detecting a Leaking Master Cylinder Regularly

The condition of a master cylinder that is still suitable for use is that there is no leakage. However, if the vehicle is quite old, even over 10 years, it is possible that the master cylinder may no longer function properly due to being prone to leaks. This leakage can occur due to various factors, one of which is age.

Now you don't need to worry, a leaking master cylinder can be detected in a fairly easy way. There are several things below that you need to know in order to detect a leaking master cylinder.

1. Brake Fluid Runs Out Easily

A common sign when the master cylinder is leaking is that the brake fluid runs out easily. If the leak is not too severe, this sign may be difficult to detect. However, it is different if the leak is quite large, then the brake fluid will run out faster due to the leakage.

A reservoir tank that does not experience leakage will certainly keep the brake fluid present. However, if there is a leak, the brake fluid will run out more easily, even when the vehicle is not in use. If your vehicle's brake fluid runs out easily, check it in detail to find out if there is a leak.

2. Dripping Brake Fluid

If the reservoir tank is leaking, the brake fluid will drip and cause it to run out easily. To detect this, you can check the bottom of the vehicle after it has been parked for a long time. If there are traces of fluid dripping, it is certain that your car's master cylinder is leaking.

This dripping fluid is the easiest way to detect a leak. You can do this by checking in the morning after the vehicle has been parked overnight. This way, you can clearly see whether the master cylinder is leaking or not.

3. There is a Whistling Sound

The last way you can do to detect a leaking master cylinder is by hearing a whistling sound. This whistling sound will come out every time you press the brake pedal. In fact, this sound can be quite loud and can be heard in the cabin or when the hood is not open.

Leaks in the master cylinder can also occur due to age factors. Even leaks can also come from seals or through damaged cables. Therefore, you must take good care of the master cylinder to prevent leaks that cause the brakes to not function normally. Be sure to check if the vehicle feels abnormal when used.

Try to detect the leaking master cylinder regularly. If a leak occurs, immediately service it to prevent further damage. Want to get more updated automotive information? Just visit the Daihatsu website. Hopefully, this review is useful and good luck trying it out.
