Mitsubishi ASX Brake Discs: OEM Part Number

Genuinely important to know: rear disc kits sold specifically for the ASX have been explicitly documented as not compatible with the related Outlander PHEV, despite platform overlap between the two — worth double-checking any kit's specific compatibility notes rather than assuming shared-platform parts are automatically interchangeable.

Front discs, most petrol/diesel variants	294mm diameter, vented, 26mm thickness, 25mm minimum
Rear discs	302mm diameter, solid, 10mm thickness, 8mm minimum

Mitsubishi ASX Brake Discs: The Part That Pads Depend On

On the Mitsubishi ASX, discs and pads don't wear independently — neglect one and the other degrades faster too, which is exactly why what starts as a routine pad change frequently turns into a disc replacement as well.

Before you buy: disc size and design vary by trim, engine size and whether your car has the standard or "sport" brake package. Always confirm against your VIN before ordering.

Mitsubishi ASX 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 ASX typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.

A Genuinely Important Habit Worth Building: Checking for Open Recalls — Mitsubishi ASX Brake Discs

Mitsubishi has faced multiple confirmed recalls on related models specifically addressing corrosion in brake-related components, including parking brake shafts and caliper boots not being properly water-sealed, traced back to a UK dealer's original field report about rear brake disintegration. It's genuinely worth checking your specific VIN against Mitsubishi's official recall register directly, particularly on a used car where you can't be certain a previous owner had any relevant recall work completed.

Worth knowing this wasn't resolved by a single fix: the recall history on related models shows the initial anti-corrosion coating fix was later found not to have fully resolved the issue in service, leading to a further recall — worth checking your VIN against all relevant recall campaigns rather than assuming an earlier recall visit closes the matter.

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.
