Parts for your 2013 Subaru Impreza-Brake pad wear indicator

2013 Subaru Impreza brake pad wear indicator

For the 2013 Subaru Impreza (GP/GJ), a brake pad wear indicator is very much relevant and fitted. Technical references from the Subaru Impreza 2012–2016 Service Manual (Brake/Disc Brake sections) specify a metal wear indicator tab on the inner disc brake pad, and Subaru Genuine Parts catalogues for MY2013 pad kits list a wear indicator (often called a “squealer”). There’s no electronic pad-wear warning light on the dash for this model, it uses the proven mechanical tab to alert the driver.

The little metal tab on the pad is designed to gently brush the rotor once the friction material nears its service limit, usually around a couple of millimetres. That contact creates a high-pitched chirp that tends to be more obvious at low speeds or light braking. It’s the Impreza’s built-in nudge to schedule a pad change before things wear too far and start scouring the rotors.

During servicing, a brake check should include measuring pad thickness, inspecting the rotor surface and making sure the wear indicator tab is intact and correctly positioned. On this Impreza, the indicator tab is installed on the inner pad as per Subaru’s service guidance. If the tab has been bent off, removed, or fitted to the wrong pad, the warning won’t work as intended.

When replacing pads, the indicator comes as part of the new inner pad—no need to buy it separately. It’s smart practice to replace pads in axle sets, inspect the rotors for minimum thickness or scoring, clean and lubricate the slide pins with high-temp brake grease, and bed-in the new pads as recommended by the pad maker. If the chirp has turned into a constant metallic scrape, stop driving and get the brakes checked—at that point the pad may be beyond the indicator and into the backing plate.

• Listen for a light, repeatable chirp that goes away when braking firmly—time to plan a pad replacement.
• Check pad thickness at each service (about every 10,000–15,000 km in typical AU/NZ use).
• Fit the inner pad with the indicator tab in the specified position, don’t bend or delete the tab.
• After pad replacement, bed them in and avoid heavy braking for the first few heat cycles.

Popular questions

Does a 2013 Subaru Impreza have a brake pad warning light?
No. This model uses a mechanical wear indicator tab on the pad (a squealer), not an electronic sensor or dash warning light. When you hear a consistent high-pitched chirp that eases with firm braking, it’s signalling the pads are due.

Which wheels on a 2013 Impreza have wear indicators?
The front disc pads are fitted with wear indicator tabs from the factory. Many AU/NZ variants with rear disc brakes also use tabs on the rear pads. If a particular trim has rear drum brakes, those don’t use a pad wear indicator.

Can the wear indicator be replaced on its own?
It’s integrated with the pad backing on this Impreza. If the tab is missing or damaged—or you’re hearing the chirp—the correct fix is to replace the brake pads on that axle and inspect the rotors and hardware at the same time.
