Brake fade refers to a condition where your car’s braking system loses effectiveness — a situation commonly described as “brakes not responding” or “brake pedal sinking”. This is highly dangerous as it leads to increased stopping distances or, in severe cases, the inability to slow down or stop the vehicle even when pressing the brake pedal all the way down.

How to Recognize Brake Fade

• The brake pedal feels softer or sinks deeper than usual.

• You have to apply more force to get the same braking effect.

• The car doesn’t slow down as expected and continues to glide forward.

• You notice a burning smell near the wheels due to overheating of the brake pads or discs.

Why Is Brake Fade Dangerous?

Brake fade means losing control of the vehicle’s ability to stop. It typically occurs in these situations:

• Long downhill driving: Constant braking builds up heat in the system.

• Sudden hard braking at high speed: Puts intense, immediate load on the brakes.

• Overloading the vehicle: Increases braking demands beyond normal limits.

Main Causes of Brake Fade

1. Friction Fade (Pad/Disc Fade)

Occurs due to extreme and continuous friction between the brake pad and disc, generating high heat (typically over 400–500°C). At such temperatures, the brake pad material can break down and release gases that form a barrier between the pad and disc, greatly reducing friction.

Symptom: The brake pedal still feels firm, but the car doesn’t slow down effectively.

2. Fluid Fade (Brake Fluid Fade)

Heat from the brake discs and calipers transfers to the brake fluid. If the brake fluid has a low boiling point or has absorbed moisture over time, it can boil and create vapor in the brake lines.

Symptom: The brake pedal feels soft or “spongy” and sinks almost to the floor, with minimal braking force.

How to Prevent Brake Fade

Keeping your braking system in optimal condition is critical for safety. Here’s what you should regularly check and replace:

1. Brake Pads

Check pad thickness regularly. If the brake pad is 3 mm or less, it should be replaced immediately.

2. Brake Discs

Replace discs if they are worn down to the minimum specified thickness. Overused thin discs lose heat dissipation ability and may crack.

3. Brake Fluid

Change the brake fluid every 2 years or 40,000 km, whichever comes first. Brake fluid absorbs moisture over time, which lowers its boiling point and increases the risk of fluid fade.

Brake fade is a serious risk that can compromise your safety. Regular inspection and maintenance of your brake pads, discs, and fluid are essential to ensure your vehicle can stop effectively — especially under heavy braking or tough driving conditions.
