You can check your brake pad thickness in five minutes with nothing but a flashlight. This simple inspection lets you know whether a mechanic's recommendation to replace your brakes is legitimate or whether you're being oversold.

What You Need
A flashlight, that's it. You don't need special tools, a jack, or mechanical knowledge. If you want to be more precise about thickness, you can buy a brake pad thickness gauge for $10-20, but it's not necessary for a basic visual inspection.
The 5-Minute Inspection Process
Step 1: Park on level ground and let the vehicle cool.
Find a safe, level place to park. If you just drove, let the brakes cool for at least 10 minutes. Hot brakes can give inaccurate readings and are uncomfortable to work around.
Step 2: Look through the wheel spokes at the brake caliper.
Stand at the front corner of your vehicle and look through the spokes of the wheel toward the brake assembly. You'll see a large metal component that looks like a clamp. This is the brake caliper. The brake pads are sandwiched between the caliper and the shiny metal rotor (the disc that spins with the wheel).
Step 3: Shine your flashlight on the edge of the brake pad.
You're looking at the side edge of the brake pad, not the face of the pad. You should see two distinct layers: a thick metal backing plate and the friction material (the darker material that does the actual braking). The friction material is what you're measuring.
Step 4: Estimate the thickness of the friction material.
You want to see at least 1/4 inch (6-7mm) of friction material. If the friction material is roughly the same thickness as the backing plate, your pads are at minimum thickness and need replacement soon. If the friction material looks thinner than two stacked pennies (about 3mm), your pads are dangerously thin and need replacement immediately.
Step 5: Check the other wheels.
Repeat this process on the rear wheels. Brake pads can wear unevenly. You might find that the front pads are thicker than the rear pads, or vice versa. Check all four wheels to get a complete picture.
What Good Brake Pads Look Like
Good brake pads have a visible gap between the friction material and the backing plate. You can see where the friction material ends and the metal begins. There's no confusion about where one layer ends and the other begins.
What Worn Brake Pads Look Like
Worn brake pads have friction material that's nearly the same thickness as the backing plate. The distinction between the two layers is minimal. At this point, you're at the end of the pad's service life. Replacement is needed soon, but you're not in immediate danger.
What Dangerously Worn Brake Pads Look Like
Dangerously worn brake pads have friction material that's thinner than a penny. The metal backing plate is nearly touching the rotor. At this point, metal-on-metal contact is imminent. Continuing to drive risks rotor damage. Replace pads immediately.
What Uneven Wear Means
If one pad is significantly thinner than the others, you have a problem beyond just worn pads. Uneven wear indicates a stuck caliper, a faulty brake hose, or a problem with the brake hardware. This needs professional diagnosis. Continuing to drive with uneven wear accelerates damage and can cause brake failure.
What to Look for on the Rotor
While you're inspecting the brake pads, take a look at the rotor. A healthy rotor has a smooth, shiny surface with no deep grooves or scoring. If you see deep grooves, the rotor is damaged and needs replacement. Damaged rotors usually result from driving on worn brake pads for too long, which is why catching pad wear early is important.
When to Stop Inspecting and Call a Professional
If you see any of these conditions, stop inspecting and call a professional:
Metal-on-metal contact between the pad backing plate and the rotor. The friction material is completely gone.
Uneven wear where one pad is significantly thinner than others. This indicates a caliper or hardware problem.
Fluid leaking from the brake caliper. This indicates a failed brake seal.
Cracks or chunks missing from the friction material. The pad is damaged and needs replacement.
Rust or corrosion on the rotor that won't wipe off. The rotor is damaged.
The DIY Inspection Advantage
Knowing how to inspect your own brake pads puts you in control. You can verify a mechanic's recommendation before you authorize work. If a shop tells you that you need new brakes and you've just inspected the pads and they look thick, you know something's wrong with that recommendation.
This doesn't mean mechanics are trying to rip you off. It means you know to make informed decisions about your vehicle's maintenance.
When Professional Inspection is Necessary
A DIY visual inspection tells you whether pads are thick or thin. It doesn't tell you everything. A professional inspection includes measuring pad thickness precisely with calipers, checking brake fluid condition and level, testing the ABS, inspecting brake lines for leaks, and performing a test drive to evaluate braking performance.
If you notice any warning signs (grinding noises, soft pedal, brake warning light), or if your DIY inspection shows pads are near minimum thickness, get a professional inspection. The cost is $50-100 and can prevent $600+ in rotor damage.
