Your brakes are arguably the most important safety system on your car. Knowing how to check your brake pads can help you catch wear early and avoid costly damage to your rotors.
What You Will Need
- A torch (flashlight)
- Your car parked on a flat surface
- About 5 minutes of your time
Step 1: Look Through the Wheel Spokes
Most modern alloy wheels have gaps between the spokes. Shine your torch through and look for the brake calliper — a metal clamp sitting over a shiny disc (the rotor). You should be able to see the brake pad material pressed against the rotor.
Step 2: Check the Pad Thickness
A new brake pad is typically around 12mm thick. If the pad material looks thinner than 3-4mm (about the thickness of two 20-cent coins stacked together), it is time to get them replaced.
Step 3: Listen for Warning Signs
Many brake pads have a built-in wear indicator — a small metal tab that contacts the rotor when pads are worn. This creates a high-pitched squealing sound, especially at low speeds. If you hear this consistently, book an inspection.
Step 4: Feel for Changes
When driving, pay attention to:
- Vibration through the brake pedal (warped rotor)
- Pulling to one side when braking (uneven wear)
- Spongy pedal (possible fluid issue)
- Grinding noise (metal on metal — pads completely worn)
When to See a Professional
If you notice any of the warning signs above, or you are unsure about what you see, bring your car into Heatherdale Automotive. A brake inspection takes about 15 minutes and can save you hundreds in the long run.
