A brake master cylinder is a hydraulic device that produces pressure used for slowing down tyre rotation. The whole braking system depends on the pressure; therefore, the master cylinder secures a significant position. That said, a malfunctioning brake master cylinder can lead to spongy or unresponsive brakes which can be a major safety hazard. However, the hazard can be exempted by observing the symptoms and getting the cylinder repaired on time.
Let’s take a closer look at the symptoms of a bad brake master cylinder and how it can be detected early.
Bad Brake Master Cylinder Symptoms
The brake master cylinder is responsible for producing pressure that travels through the brake line and makes a car brake functional. The most common bad brake cylinder symptoms include spongy or sinking brakes and brake fluid leakage. However, these symptoms may indicate other faults in the car.
Here is how to diagnose and fix the brake master cylinder failure symptoms.
Symptom 1: Decreased Braking Efficiency
The first symptom of a bad brake master cylinder is reduced efficiency. When a brake master cylinder malfunctions, braking efficiency reduces significantly. Due to reduced efficiency, the car takes longer to stop which can lead to accidents. Although reduced car brake efficiency can be due to other reasons like old brake fluid, it should not be ignored.
Symptom 2: Leakage of Brake Fluid
Any damage to the brake master cylinder and its rubber seals can cause brake fluid leakage. Leaking brake fluid from the master cylinder not only lowers the pressure but also allows foreign particles to enter the system. Due to air or dust particles entering the system, brakes can get spongy or completely unresponsive.
Aside from spongy brakes, the leakage results in lower brake fluid that can damage the whole system significantly. Here is how long you can drive without brake fluid. When you witness brake fluid leakage from the rear end of the vehicle, it’s time to get the brake cylinder repaired.
Besides the above-mentioned causes, here are some more reasons for brake fluid leakage in cars.
Symptom 3: Illuminated Brake Light
Illuminated dashboard warning lights indicate an underlying issue in the vehicle. Therefore, when a brake master cylinder malfunctions, a brake check light turns on. The brake fluid detectors and pressure sensors in modern cars have increased the efficiency of car computers, detecting a bad brake cylinder early.
Symptom 4: Spongy Brake Pedal
Spongy brakes are usually caused when air enters into the brake lines due to damaged brake cylinders. Another symptom of fluid leakage is sinking brakes, which indicates that fluid is being flushed out of the car when brake pedals are pressed.
Regardless of the reason, it is necessary to cater to both the symptoms. Although you can fix spongy brakes, seeking professional assistance is advised.
Symptom 5: Grinding Noise from Brakes
Next on the list of bad brake master cylinder symptoms is a grinding noise. When the master cylinder malfunctions it disrupts the braking system leading to uneven pressure on the pedals. This can cause many parts to wear out prematurely, leading to a grinding noise.
Symptom 6: Inconsistent Brake Performance
In the case of a bad brake master cylinder, the performance of car brakes fluctuates. Sometimes, the brake performs adequately and next time, it might lose its efficiency. The uncertainty reflects a failing master cylinder and should be addressed timely.
FAQs
How do I know if my brake cylinder is bad?
Spongy or sinking brakes, inconsistent performance and fluid leakage are the most common reasons for a bad brake cylinder.
Can you drive with a bad brake cylinder?
No, driving with a bad brake cylinder can be a safety hazard and should be avoided.
Can the brake cylinder be repaired?
Yes, the brake cylinder can be repaired, if the damages are not significant.
How do I know when my brake master cylinder needs to be replaced?
The common symptoms of a bad brake cylinder include spongy brakes, inconsistent performance, oil leakage and a grinding sound when pressing the brake.
These were all the symptoms of a bad brake master cylinder that should not be ignored. Driving with bad brakes can cause uncertainty leading to accidents. Therefore, it is necessary to get your brakes fixed as soon as the above-mentioned symptoms appear. Moreover, when buying a new or used car for sale in the UAE, consider its braking efficiency and performance.
