Signs that your car's brake system is having problems

The brake warning light illuminates on the dashboard.

One of the first and most obvious signs is the brake warning light illuminating on the dashboard. This signals that the car's braking system is experiencing problems such as low brake fluid, worn brake pads, or an electronic malfunction. When the brake warning light comes on, drivers should take their vehicle to a reputable garage for inspection immediately to avoid the risk of traffic accidents. Ignoring this warning can lead to serious consequences on the road.

Vehicle owners should check and replace brake pads regularly after every 50,000–80,000 km or after 2 years of use.

The brakes are unresponsive and ineffective.

During driving, if the driver notices that the vehicle doesn't stop immediately even when the brake pedal is fully pressed, this is a sign that the braking system is malfunctioning. This could be due to a lack of brake fluid, air entering the system, or worn brake pads. This not only reduces braking effectiveness but also increases the risk of accidents, especially during emergency situations requiring sudden braking. Any signs of unresponsive brakes should be checked and repaired promptly at a reputable garage.

Brakes not releasing (brake binding)

Normally, the brakes will automatically release when no force is applied to the pedal. However, if the brakes do not release, this indicates a faulty pull spring or return spring in the brake pads, a jammed wheel cylinder, a faulty master cylinder, or a low-oil brake caliper. Brake failure can also be caused by driver error, such as incorrect brake pedal travel or improperly adjusted parking brake. If you notice the brakes are not releasing, you should promptly check and repair the problem to ensure safe driving.

The car shakes when braking.

Car owners should check their brake fluid regularly.

Brake vibration is caused by uneven contact between the brake disc and brake pads, unbalanced wheels, or unevenly worn brake pads. Additionally, warped brake discs can also cause vibration during braking. Other components such as bearings and suspension joints can also contribute to this phenomenon. Brake vibration not only reduces braking efficiency but also poses a safety hazard, especially at high speeds or during emergency braking. Drivers should promptly take their vehicles to a repair shop for brake disc and braking system maintenance.

Oil leaking from the wheel area.

A brake fluid leak is a clear sign that your car's braking system is experiencing a serious problem and needs immediate inspection. When brake fluid leaks, the pressure in the braking system decreases, severely affecting the car's braking ability. Drivers can detect brake fluid leaks through oil stains under the car or near the wheels. The cause may be damaged oil lines or worn parts such as pistons and brake pads. To ensure safety, when a brake fluid leak is detected, drivers should take their car to a reputable garage or authorized service center for timely inspection and repair.
