Parts for your 2017 Mitsubishi Asx-Brake pad wear indicator

2017 Mitsubishi ASX brake pad wear indicator — what it does and how to look after it

Based on Mitsubishi’s factory literature and common parts listings, the 2017 Mitsubishi ASX is fitted with a mechanical brake pad wear indicator on the front brake pads. It’s the simple “squealer” tab that lightly touches the disc and makes a high-pitched noise when the friction material is nearly worn out. There’s no electronic sensor wire and no dedicated dash warning lamp for pad wear on this model.

• Mitsubishi Motors Service Manual (ASX/RVR/Outlander Sport, 2010–2017), Group 35A – Front Disc Brakes: notes a pad wear indicator plate that emits a warning sound when pad thickness is low.
• Mitsubishi Motors ASA/Global Electronic Parts Catalogue for 2017 ASX: front pad sets shown with a mechanical indicator tab, no pad wear sensor harness listed.
• Common aftermarket catalogues (e.g., Bendix, Bosch) for 2010–2019 ASX list front pads with a mechanical squeal indicator and no electrical lead.

On the 2017 ASX, the wear indicator’s job is dead simple: warn early, before metal-to-metal contact. When the tab begins to sing under light braking, the pads are due. Keep driving long enough and that squeal can turn to a grind, which usually means the pads are done and the rotors may be on the line too.

As part of routine servicing, it pays to have the pad thickness measured and the indicator tab’s position checked. Most ASX front pad sets have the indicator on one inner pad, it must be installed on the correct side and in the correct orientation so it meets the disc as the pad approaches the last couple of millimetres. If the tab’s missing or bent away, you lose that early warning.

When replacing pads, do both fronts together, clean and lubricate the slide pins with high-temp brake grease, and refit any shims correctly. Don’t try to reuse or “bend back” a tired indicator tab—fit quality pads that include a fresh tab. After refitting, bed the pads in with a series of gentle stops from suburban speeds to stabilise friction and avoid glazing. If the indicator has already been squealing, inspect rotor thickness and condition, replace or machine only if within the disc’s stamped minimum.

For everyday city runs and the odd weekend away, most ASX owners will see pad life vary with driving style—short trips, steep hills, towing, and stop–start traffic in Aussie and Kiwi cities can shorten the interval. A quick listen on light brake application is a handy tell: regular, sharp squeal that eases with firmer pedal pressure usually points to the wear tab doing its job.

• Does the 2017 ASX have a brake pad warning light?
  There’s no dedicated dash light for pad wear on the 2017 ASX. It uses a mechanical squeal tab on the pads to alert the driver audibly when the pads are nearly worn out. If a brake warning symbol appears, it relates to the hydraulic system or parking brake, not pad wear.
• Which wheels have the wear indicator on a 2017 ASX?
  Front pads are commonly supplied with a single mechanical wear tab on one inner pad. Rear pads on many trims don’t have a tab from factory. Always check the specific pad set being installed—some aftermarket rear pads may include a tab, but the car does not use an electrical sensor.
• Is it safe to drive when the wear indicator is squealing?
  Short distances are usually fine, but it’s a prompt to book a pad replacement soon. If the noise turns into a harsh grind or scraping under any braking, stop driving and have the brakes inspected—continuing can damage the rotors and push up repair costs.
