When to change your brake pads
“Take a look at the edge of the pad inside the caliper for an indication of how worn they are”
It’s important that your rear brake pads are examined whenever the car is serviced and replaced when necessary, for safe operation. Your car may have an electronic sensor and warning light for when the pad has worn down, or a metal tab that squeals, but many don't. The best way to know for sure is to jack up the car, remove a rear wheel and examine the pads directly. Always check the rest of the brake system when replacing the pads - if the discs/rotors are worn thin, grooved, or warped have them machined smooth or consider replacing them.
All cars are slightly different, so if it is time to change your brake pads, use our before you begin checklist, and find your car for specific instructions.
