Mitsubishi Outlander Brake Discs: Specs, Fitment & Wear Symptoms
Confirmed: a UK dealer's 2014 field report about rear brake disintegration led to a recall of over 170,000 vehicles — and critically, even the recall's own anti-corrosion fix later failed, requiring a third separate recall.

Mitsubishi Outlander Brake Discs: The Part That Pads Depend On
On the Mitsubishi Outlander, wear on one of this pair accelerates wear on the other, so a pad change booked as routine maintenance often turns up discs that have quietly deteriorated alongside them.
Mitsubishi Outlander Brake Discs: What They Do
Brake discs provide the surface the brake pads clamp against to slow the car, converting momentum into heat through friction. Larger, sportier trims of the Outlander typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.

Confirmed: A Genuine Recall Traced Back to a UK Dealer Report — Mitsubishi Outlander Brake Discs
This is genuinely worth knowing about the origin and scale of a confirmed safety recall: Mitsubishi received a field report from a UK dealer in October 2014 describing an instance of rear brake disintegration, which the company's own investigation traced to corrosion causing the parking brake shaft to stick. This led to a recall covering more than 170,000 vehicles across the 2013-2016 Outlander and Outlander Sport range, addressing parking brake shafts and rear brake caliper boots that weren't properly water-sealed, allowing moisture to cause extensive corrosion. Genuinely worth knowing: this wasn't a single, one-off fix — there have been three separate recalls addressing this same underlying concern, since the second attempted fix, an anti-corrosion coating applied to the affected parts, was later found not to have fully resolved the issue in service. It's genuinely worth checking your specific VIN against all three recall campaigns rather than assuming an earlier recall visit means the concern is definitively closed.
It's also genuinely worth knowing that a burning smell alongside noticeably hot wheels after releasing the parking brake can indicate a seized, corroded rear caliper rubbing against the disc — worth having this checked promptly given the genuine risk of further damage and reduced braking performance if left unaddressed.
