How to Tell When Brake Pads Are Worn Out? 5 Warning Signs You Shouldn't Ignore

Brake pads are a critical part of the brake system, creating friction against the brake disc to slow down and stop the car. If brake pads wear down too thin, braking efficiency drops, stopping distance increases, and damage to the brake disc may occur, along with an increased risk of accidents.

If your car shows any of the following symptoms, have your brake system checked as soon as possible.

1. A Loud Noise When Braking

Unusual noise is the most common warning sign.

• A squealing sound is usually caused by brake pads starting to wear thin, or the wear indicator contacting the brake disc
• A grinding sound like metal scraping means the brake pads may be completely worn, with metal now touching the brake disc. Replace the brake pads immediately to prevent damage to the brake disc

2. Pressing the Brake Pedal Deeper Than Usual

If you need to press the brake pedal deeper than usual, the car still rolls before stopping, or you need to pump the brakes several times to slow down, this may be a sign that the brake pads are wearing out or there's a problem with the brake system. Have it checked immediately.

3. A Brake Warning Light on the Dashboard

Many car models have sensors that monitor brake pad wear. When the brake pads become thin to a certain level, or brake fluid drops below the standard level, a warning light will appear on the dashboard. Don't ignore this signal.

4. Needing to Pull the Handbrake Higher Than Usual

If you need to pull the handbrake higher than before to keep the car stationary, it may be caused by worn brake pads or a worn brake system. Have an expert technician inspect it before further use.

5. Brake Fluid Level Dropping Abnormally

If the brake fluid level drops without any visible leak, it may be caused by worn, thinning brake pads, which cause the caliper piston to extend further and use more brake fluid. While this is normal to some extent, you should also check the thickness of the brake pads.

Don't Wait Until the Brake Pads Are Completely Worn Out

Replacing brake pads on schedule, along with regularly checking the brake disc and brake fluid, will help the brake system perform at full efficiency, increase safety on every drive, and reduce future repair costs from potential damage to the brake disc.

If you notice any of the warning signs above, you can bring your car in to have the brake pads, brake system, and brake fluid checked at any B-Quik branch, where our expert technicians provide advice and comprehensive service.

FAQ Section

Q: When should brake pads be replaced? A: Generally, they should be checked every 10,000–20,000 kilometers and replaced when they are thinner than standard or show abnormal symptoms.

Q: What sound do worn brake pads make? A: Usually a squealing sound when the pads start to thin, and once worn down to the metal backing plate, a grinding sound occurs, which requires immediate replacement.

Q: Can I keep driving with worn brake pads? A: No, you should not, as it will increase stopping distance, risk an accident, and may damage the brake disc, resulting in higher repair costs than before.

Q: Does a drop in brake fluid always mean the brake pads are worn out? A: Not always, but it is one of the signs that may indicate worn brake pads, so you should check both the brake fluid level and the thickness of the brake pads.
