Brake Pad Wear Indicator for the 2020 Mitsubishi ASX

Based on Mitsubishi’s factory Service Manual for ASX/RVR/Outlander Sport (MY2020, Brake section) and the Mitsubishi ASA electronic parts catalogue, the 2020 Mitsubishi ASX uses a mechanical brake pad wear indicator tab integrated into the disc brake pads. There’s no electronic pad-wear light in the instrument cluster, instead, the metal “squeal” tab provides an audible warning as the pads approach end of life. Major aftermarket catalogues for the ASX also supply pads with built-in wear tabs, reinforcing that this vehicle relies on a mechanical indicator.

This wear indicator’s job is simple and effective: when the friction material is nearly done (typically around 2 mm remaining), the small metal tab lightly contacts the rotor and creates a high-pitched squeal during gentle braking. That sound is the cue to book the ASX in for pads before the rotor cops unnecessary damage. Because it’s a mechanical setup, you won’t see a dash warning—your ears do the alerting.

As part of regular servicing, the indicator doesn’t get replaced on its own. It’s built into the pad backing plate and comes as part of the new pad set. During each service or roughly every 10,000–15,000 km (or sooner if driving is mostly urban or hilly), a visual pad thickness check should be done. If the ASX starts squealing under light pedal pressure, especially at low speeds, that’s often the indicator tab talking. At roughly 2–3 mm pad thickness, plan a pad replacement to protect the rotors and keep braking performance crisp.

• Always replace pads in axle sets, the wear tab orientation matters—fit the tab to the correct leading/trailing edge per the service manual.
• Clean and lubricate caliper slide pins and pad abutments, avoid bending or trimming the wear tab.
• If a squeal persists immediately after a pad change, the indicator may be on the wrong side or touching the rotor—recheck fitment.

Timely pad replacement when the indicator sounds helps maintain safe stopping distances, avoids rotor machining or replacement, and keeps the ASX quiet and confidence-inspiring on Aussie and Kiwi roads.

Popular questions

Does the 2020 Mitsubishi ASX have a brake pad warning light?
No. The ASX uses a mechanical wear indicator tab on the pads. When the pads are low, the tab squeals against the rotor. There’s no electronic pad-wear signal sent to the dash on this model.

When should the pads be replaced after the indicator starts squealing?
Book the car in promptly. The squeal typically begins around 2 mm of friction material remaining, and continued driving risks rotor damage and longer stopping distances. A quick inspection will confirm thickness and whether rotors need attention.

Can the wear indicator be replaced by itself?
It’s part of the pad assembly, so the practical fix is to replace the pads. Some pads use clip-on tabs, but best practice is to fit a quality pad set with the correct built-in indicator and follow the ASX torque and fitment procedures.
