Brake pad wear indicator for the 2018 Mitsubishi ASX

On the 2018 Mitsubishi ASX, a brake-pad-wear indicator is indeed used — but it’s the simple, reliable mechanical type rather than an electrical sensor with a dash warning light. Mitsubishi’s factory workshop documentation for the ASX/Outlander Sport platform describes a spring-steel “wear indicator” tab on the brake pad, and the Mitsubishi ASA parts catalogue lists pad kits that include this indicator. Major aftermarket catalogues for ASX pads (e.g., Bendix, DBA, TRW) also specify pads supplied with an integrated squealer tab. The owner’s handbook guidance about a persistent high-pitched squeal prompting inspection aligns with this setup.

What does it do? The wear indicator tab is fixed to one of the pads (commonly the inboard front pad). As the friction material wears down, the tab eventually touches the rotor and creates a sharp, high-pitched squeal. That sound is the nudge to book a brake check before the pads run too thin. It’s designed to start making noise with a few millimetres of pad left — enough time to sort fresh pads without damaging the discs. There’s no wiring, no sensor to reset, and no warning light on the dash, the audible cue is the whole point.

Replacement and servicing are straightforward. The indicator is part of the pad, so once it squeals consistently under light braking, the pad set should be replaced. On the 2018 ASX, wear tabs are typically on the front axle, some rear pad sets may also include them depending on brand, so it pays to check both ends. During pad replacement, a good technician will measure rotor thickness and runout, clean and lubricate slide pins, fit new shims where required, and confirm pedal feel. After new pads are fitted, follow the supplier’s bedding-in procedure to ensure smooth, quiet braking and even wear.

Plan on having the pads visually inspected at each service or roughly every 10,000–15,000 kilometres, sooner if the vehicle tows, carries loads, or does lots of urban stop–start driving. A brief morning squeal in damp conditions can be normal, but a persistent, metallic screech under gentle braking is the classic wear-indicator sound. When in doubt, organise a professional inspection to keep the ASX braking sweet and your discs in good nick.

• Book a brake check if there’s a regular high-pitched squeal under light braking.
• Replace pads as a set on the axle, the wear tab comes built-in.
• Have rotor condition and slide pins checked at the same time.

FAQs

Does the 2018 Mitsubishi ASX have a brake pad warning light?
No. The ASX uses a mechanical wear indicator tab on the pad that makes a high-pitched squeal when the pads are nearing the end of their service life. There’s no electronic sensor or dash light to reset.

Which wheels on the 2018 ASX have wear indicators?
The front pads are typically fitted with the mechanical wear indicator. Some rear pad sets from certain brands also include a squealer tab, but not all do. Always inspect both axles during a brake service.

Can the wear indicator be replaced on its own?
No. The indicator tab is part of the brake pad assembly. When it starts squealing consistently, it’s time to replace the pad set on that axle. The new pads will include a fresh indicator tab.
