Parts for your 2019 Holden Colorado-Brake pad wear indicator

2019 Holden Colorado brake pad wear indicator – is it a thing?

Short answer: a discrete electronic brake pad wear indicator isn’t fitted to the 2019 Holden Colorado. Technical documentation such as the Holden RG Colorado (MY18–MY20) Service Manual – Brakes, the GM/ACDelco parts catalogue for RG Colorado, and common aftermarket pad listings (e.g., Bendix, Protex, DBA) all show no electrical pad-wear sensor circuit or dash warning for pad wear on this ute. The front brakes use mechanical “squeal” tabs built into the pads, and the rear brakes are drums, which don’t support electronic pad-wear sensing.

Why doesn’t it use an electronic indicator? The Colorado’s braking package is designed to be robust and easy to service for work and off-road use. Mechanical wear tabs are reliable in mud, water and dust, and they avoid extra wiring or connectors that could cop damage. It keeps costs down without sacrificing safety, so long as routine inspections are done.

• Front: Disc brakes with pads that have integral wear tabs (“squealers”) to give an audible chirp when the pad gets low.
• Rear: Drum brakes with inspection points, shoes are checked by removing the rubber plug and visually measuring lining thickness.

What owners can expect is no dash light for worn pads. Instead, servicing relies on scheduled inspections and the audible cue from the wear tab. Any Colorado that develops a continuous high-pitched squeal under light braking is signalling it’s time to check pad thickness.

Good servicing practice for a 2019 Colorado includes:

1. Inspect front pad thickness at every service (or around every 10,000–15,000 kilometres if driving is heavy-duty). Replace pads when they’re near the service limit specified in the manual, many techs change at roughly 3 mm remaining for safety.
2. Check rear drum shoes through the inspection port, and assess braking performance and handbrake operation.
3. Replace fitting hardware (shims/clips/springs) if worn, and clean/lubricate sliding surfaces to prevent uneven wear.
4. After pad/shoe replacement, bed-in the brakes per the pad manufacturer’s guidance, and keep brake fluid changes on a 2-year cycle.

If anyone sells an “electronic brake-pad-wear-indicator” for this model, it’s either universal add-on gear or mislabeled. For the RG Colorado, order quality front pads with built-in wear tabs and follow routine inspections—simple, tough and effective. As always, variants can differ by market or prior modifications, so a quick VIN-based parts check is smart.

Popular questions

How does a 2019 Holden Colorado tell you the front pads are worn?

There’s no dash warning. The front pads have mechanical wear tabs that chirp when the pad gets low. Technicians also measure pad thickness at service—if it’s near the limit, the pads are replaced before metal-to-metal contact occurs.

Can an electronic brake pad wear sensor be retrofitted to a 2019 Colorado?

Not practically. The Colorado doesn’t have a factory circuit or cluster warning for pad wear. Aftermarket “universal” kits exist but add complexity without integrating to the dash. Regular inspections and quality pads with wear tabs are the reliable approach.

What brake pads should be used on a 2019 Colorado—do they need special sensors?

Choose pads that suit the RG Colorado front calipers and include wear tabs (“squealers”). There’s no need for sensor wiring. For the rear, it runs drum shoes, so you’ll be selecting the correct shoe set rather than disc pads with sensors.
