These are pretty simple devices, really. Basically, they’re a little piece of metal embedded in your brake pads. When your pads wear down to a certain thickness, this indicator starts to rub against the brake rotor – that's the disc the brake pads squeeze. That rubbing creates a squealing or grinding noise, or sometimes lights up a warning light on your dash. It's a warning signal, telling you it’s time to get your brakes checked. Some vehicles use an electrical sensor instead of a physical indicator; that sends a signal to the dash when the pads get thin. Both do the same job, just different methods. Think of it as an early warning system for your brakes. It's not actually part of the braking process itself, it just monitors how much pad material you have left. It's there to prevent you from wearing your pads down to nothing, which would cause damage to the rotors – those are much more expensive to replace. It acts like a shield, alerting you before you get into a really bad situation. It’s hugely important for safety and preventing bigger repair bills down the road. Ignoring that squealing or warning light is asking for trouble. Worn – down pads mean longer stopping distances, and eventually, metal – on – metal contact which can seriously damage your rotors and calipers. You’ll notice if it's gone bad – it's that high – pitched squeal when you brake, especially at lower speeds. If you need a new one, you can find them pretty easily. Fixparts Online has a good selection, and it's usually a fairly straightforward replacement when you’re doing your brake pads. It’s just one of those little parts that saves you a lot of headaches if it works correctly. Drive with confidence: Wear Indicator (MPN 4.65090) is backed by a 12-month warranty!
