2 Causes and Signs of Low Brake Fluid – When you open the engine room of your car and then you find the condition of the brake fluid is low, maybe you will be a little worried. And indeed you have to worry about it. Driving with low brake fluid can endanger anyone in the car and even other people. This is because there are many possibilities that can occur due to failure of the brake system to work on your vehicle.
The symptoms that appear on several vehicles indicate that the brake fluid is low, especially when driving. The following symptoms appear in vehicles when brake fluid is low:
- Brake warning light indicator lights up
- Brake pedal distance increases (in)
- Abnormal braking conditions – braking distance is reduced.
On the reservoir tube, you will see two mark lines, max and min as shown. The upper line (max) is the maximum limit of brake fluid level, while the lower line (min) is the minimum limit of brake fluid level.
If you find that brake fluid is at the bottom of the line, this indicates that brake fluid is low. We recommend that you do a quick check on the brake system to determine the cause of the low brake fluid level and how to do it.
2 Causes and Signs of Low Brake Fluid
In connection with the reduced amount of brake fluid, here are the causes and ways to solve the problem while traveling.
1. The brake pads and brake shoes are worn
When you see brake fluid in a low position, try to pay attention to the condition of the brake pads. Wearing brake pads often causes the brake fluid to run low. It should be noted that brake fluid is used to push the pistons into the brake calipers.
The thickness of the brake pads greatly affects the amount of brake fluid in the calipers. The thicker the brake pads, the less fluid there is in the calipers. Vice versa, thin and worn brake pads cause the calipers to require more brake fluid.
When the brake pads are worn, the brake piston will be pushed forward more. This results in more space in the brake caliper which must be filled with brake fluid.
In this case, you must check the condition of the brake pads. If it is very worn out, you should replace the brake pads. However, if the brake lining is still in good condition, you can simply add a sufficient amount of brake fluid to the reservoir tube.
2. Brake fluid leak
Leaking brake fluid will reduce brake fluid and become a serious problem. If this happens, it is mandatory for you to fix it immediately. Brake fluid leaks can cause any brake system to fail. The safety of you and whoever drives your car is at stake.
For the problem of brake fluid leakage, you must do a proper and accurate check to find the location of the brake fluid leak because there are quite a lot of components in the brake system that are related to brake fluid.
However, there are components in the brake system that most often experience brake fluid leakage, which is in the following position.
- Brake master cylinder (located in the engine compartment)
- Brake calipers (for disc brake systems on the front wheels)
- Wheel cylinders (for drum brake systems on rear wheels)
- Load sensing proportional valve (usually located under the car close to the rear brake)
- Brake hoses on each wheel
It is advisable to check for brake fluid leakage by a certified technician or mechanic to ascertain which part of the brake is damaged and what actions are appropriate for brake fluid leakage.
Car brakes are a major safety part. Regardless of whether there is ABS or not and maybe another safety system, the brake system is still the main thing. Vehicles that go fast can be reduced to a stop due to car brakes. Therefore, immediately observe if you find that the brake fluid is very little. Replace and repair the brake system immediately will extend your life at least while driving.
