Inspect Your Brake Pads

Your brakes are the most important safety system on your car. Knowing how to inspect them yourself means you'll never be caught off guard by worn pads — and you'll never pay a shop to tell you something you could have checked yourself.

Step-by-step instructions

  1. 1

    The quick check (no tools needed)

    Look through the wheel spokes at the brake rotor (the shiny disc) and the caliper (the clamp around it). You can often see the brake pad squeezed between the caliper and rotor. If the pad looks thinner than a quarter-inch, it's time to replace them.

    This works best on cars with open-spoke wheels. If your wheels are solid, you'll need to remove them.

  2. 2

    Listen for warning signs

    A high-pitched squeal when braking is usually the wear indicator — a small metal tab designed to make noise when pads get low. Grinding means metal-on-metal contact, which means the pads are gone. Get to a shop immediately.

    Squealing that goes away after the first stop in the morning is usually just surface rust burning off — normal and harmless.

  3. 3

    Remove the wheel for a closer look (optional)

    If you want a precise measurement, safely jack up the car, remove the wheel, and look at the pad directly. New pads are about 10–12mm thick. Replace at 3mm or less.

    While the wheel is off, check the rotor surface too. Deep grooves or scoring mean the rotor may need resurfacing or replacement.

  4. 4

    Check all four wheels

    Front brakes wear faster than rear brakes because they do most of the stopping work. But check all four — uneven wear can indicate a stuck caliper or other issue.

    If one side is significantly more worn than the other, have a mechanic look at it.

  5. 5

    Know when to go to a shop

    Inspecting is a DIY skill. Replacing brake pads is also doable for beginners, but it requires more tools and confidence. If you're not ready to replace them yourself, take your inspection findings to a shop — you'll have a much better conversation knowing what you already know.

    A shop that respects you will show you the worn pads before replacing them. Ask to see them.

You did it.

You don't need to replace the pads yourself to benefit from this guide. Just knowing what to look for puts you in control.
