Wabco 12480021 Wear Indicator Pan

Description

The Wear Indicator Pan 17 is a critical component of the brake system, designed to indicate when brake pads have reached their minimum thickness. It's used in conjunction with brake pad wear sensors to provide a warning to the driver when brake pad replacement is needed, ensuring safe and reliable braking performance. This Wabco component, with MPN 12480021, helps maintain optimal braking efficiency and prevents damage to braking components. Its dimensions are 22 x 45 x 301 mm. This OE specification component provides accurate wear indication, contributing to vehicle safety and reduced maintenance costs.

Key Features & Benefits

Basically, it’s a pretty simple device. It’s a metal tab embedded in your brake pads. When your pads get worn down to a certain thickness, that tab makes contact with the brake rotor – that’s the disc the pads squeeze against. This contact creates a squealing noise, or sometimes lights up a warning light on your dash. It’s its job to tell you your brake pads are getting thin. Some systems are a bit more sophisticated, using electrical contacts to trigger the light directly, but the core idea is the same. It’s part of your braking system, obviously. But it doesn’t actually stop the car. It acts like a shield – a warning system, letting you know the parts that do stop the car—your pads—need attention. Without it, you might not realize your pads are dangerously thin until you’re hearing metal grinding on metal, which means you’re damaging your rotors and reducing your stopping power.

Symptoms, Risks & Replacements

It’s super important for safety and saving money down the road. Ignoring the warning—whether it’s the squeal or the light—can lead to severely damaged rotors, calipers, and even potential brake failure. Replacing worn pads when you get the signal from this little part is much cheaper than fixing all the damage that can occur if you wait too long. You’ll notice if it's gone bad because the warning won't happen, or it might be constant even with good pads. We stock these at Fixparts Online, and getting a new one is a small investment for a lot of peace of mind.
