Parts for your 2013 Subaru Outback-Brake pad wear indicator

2013 Subaru Outback Brake Pad Wear Indicator

Based on Subaru’s technical literature for the BR/BM Outback platform (2010–2014), the 2013 Subaru Outback is fitted with mechanical brake pad wear indicators (often called squeal tabs) on its disc brake pads. The factory Service Manual for the brake system lists a wear indicator plate on the pad assembly, and the Owner’s Manual advises that a high-pitched squeal when driving can be the pad wear indicator contacting the rotor, signalling it’s time for inspection. There is no dedicated electronic pad-wear warning light on the dash, the audible squeal is the built-in alert, while the brake warning lamp is for the parking brake/low fluid and not pad thickness.

What does the brake pad wear indicator do on a 2013 Outback? It’s a small metal tab fixed to the pad backing plate. As the friction material wears down, the tab eventually meets the rotor and makes a sharp, high-pitched squeal—especially under light braking—letting the driver know the pads are near their service limit. It’s a simple, reliable system that’s easy to check during routine servicing.

For ongoing care, a visual check of pad thickness at each service interval (or roughly every 10,000–15,000 km, depending on use) is smart. If the indicator has started to sing, plan a pad replacement soon to protect rotors. Pads should always be replaced in axle sets (both fronts or both rears together). When fitting new pads, ensure they include wear indicators and that the indicator tab is installed in the correct position (usually the inboard pad). Technicians should also measure rotor thickness and runout, replace or machine rotors if they’re below spec or scored, renew hardware/shims, and apply appropriate brake grease to contact points.

There’s no electronic reset because the Outback’s system is mechanical. Once new pads are in, bed them in with a series of moderate stops from suburban speeds to stabilise friction material and reduce the chance of squeal. If a replacement pad set doesn’t include a wear indicator tab, there may be no audible warning the next time around—so be extra diligent with scheduled inspections. And if the brake warning light on the dash comes on, that’s for the parking brake or fluid level, not pad wear—check fluid and get the system inspected under the bonnet promptly.

• Tell-tale signs: chirp or squeal under light braking, longer stopping distances, or visible pad material down to a few millimetres.
• Service tip: replace pads around 2–3 mm remaining thickness to avoid rotor damage and keep pedal feel consistent.

Popular questions

Does the 2013 Subaru Outback have an electronic pad wear light?
No. It uses a mechanical wear indicator (squeal tab) on the pads. The dash brake lamp is for the parking brake and/or low brake fluid, not pad thickness. If there’s squealing that comes and goes with light braking, that’s the wear tab doing its job.

Are wear indicators fitted on the front and rear pads?
From the factory, the Outback’s disc pads typically include wear indicator tabs—commonly on the inboard pad of each caliper. Some aftermarket pads may omit the tab on one axle, so it pays to check the kit contents when servicing.

When should the wear indicator (and pads) be replaced?
The indicator is part of the pad assembly, so it’s replaced with the pads. Plan pad replacement once the tab starts to squeal or when friction material approaches 2–3 mm. Always replace pads in axle pairs and inspect rotors at the same time.
