Parts for your 2020 Subaru Impreza-Brake pad wear indicator

2020 Subaru Impreza brake-pad-wear-indicator

For the 2020 Subaru Impreza, a brake-pad-wear-indicator is absolutely used. Technical sources including the 2020 Impreza Owner’s Manual (Brakes section: brake pad wear indicators), Subaru Service Manual (Brake/BR section for the 2017–2021 platform), and OEM pad kit documentation all describe the factory pads having a mechanical wear indicator “squealer” tab. There isn’t an electronic dash warning on this model, instead, the tab makes a high-pitched squeal when pad material is nearing its service limit, prompting inspection and pad replacement.

What’s the point? The wear indicator is a simple, reliable way to let drivers know the pads are getting thin before they turn into metal-on-rotor drama. When the pad reaches a set thickness, the indicator lightly touches the rotor, creating that unmistakable squeal at low to moderate speeds. It’s a smart bit of insurance that helps avoid costly rotor damage and keeps stopping distances consistent across Aussie and Kiwi roads.

As part of routine servicing on a 2020 Impreza, technicians should check pad thickness at each service, confirm the indicator tab is intact and correctly oriented to the direction of rotation, and ensure the pad hardware moves freely. When pads are replaced, the wear indicator comes new with most pad sets, if the design uses a transfer tab, it must be moved to the new inner pad and positioned exactly as per the Subaru procedure. Don’t bend the tab out of the way to silence a squeal—that masks the warning and risks rotor damage. If a squeal is heard consistently (not just after washing the car or after a cold start), it’s time to book a brake inspection and likely a pad replacement.

Good practice in local conditions includes cleaning off coastal salt and red dust that can make indicators noisy, using quality pads that include the correct Subaru-style indicator, and bedding the new pads properly. Drivers can expect the indicator to make itself known earlier if the car does lots of city kilometres, hill work, or towing. Keep an ear out, and have the brakes measured rather than guessing—simple, safe, and it saves money in the long run.

• Listen for a persistent high-pitched squeal under light braking.
• Measure pad thickness at each service and replace pads before they’re fully worn.
• Ensure the indicator tab is fitted in the OEM-specified position on the inner pad.

Popular questions about 2020 Subaru Impreza brake-pad-wear-indicators

Does the 2020 Impreza have an electronic brake wear light?
No. The 2020 Impreza uses a mechanical wear indicator tab on the brake pad that squeals as the pad thins. There’s no dedicated dash lamp for pad wear on this model, so that audible cue is the sign to organise an inspection.

When should the wear indicator or pads be replaced?
If the squeal is consistent during light braking, the pads are near the end of their life. A technician should measure pad thickness and, if at or near the service limit, replace the pads (the new set will include a fresh indicator). Occasional noise right after washing or in heavy rain may be normal surface moisture and not a wear warning.

Can the indicator be bent back or removed to stop the noise?
Best not. Bending or removing the tab defeats its safety purpose and can lead to rotor damage once the pads wear further. Proper fix: inspect the brakes, replace worn pads, clean and lubricate the hardware, and ensure the new indicator is correctly positioned.
