Mini Countryman Brake Discs: Specs, Fitment & Wear Symptoms

On the Countryman, skimming discs while still fitted to the car is genuinely cheaper and often more accurate than full replacement.

Genuinely worth knowing: M Sport Brake (option code S2NHA) and standard brakes use genuinely different rear disc sizes on F60 JCW models — always confirm which option your specific car has before ordering, since electric parking brake models specifically use a 300mm rear disc.

F60 Cooper S (2016-2018), rear discs	259mm diameter, solid, 10mm thickness, 8.4mm minimum

The Part That Pads Depend On

Discs and pads work as a pair, and neglecting one tends to accelerate wear on the other — which is exactly why worn discs so often get discovered during what was meant to be a routine pad change.

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.

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

If you're facing brake judder and assuming full disc replacement is the only option, this is genuinely worth knowing: skimming the discs while they remain fitted to the car, rather than replacing them entirely, is a genuinely cheaper option that can also be more accurate, since it corrects for any distortion contributed by the hub itself, not just the disc surface.

A genuinely important diagnostic point worth knowing: if judder returns even after fitting genuinely new discs and pads, this points strongly toward a sticking or binding caliper rather than a problem with the new disc itself, since a caliper that isn't releasing properly keeps constant pressure and heat on the disc.

It's also genuinely worth knowing that not properly cleaning the caliper pistons before fitting new pads can push accumulated rust and grime into the caliper's seal, causing it to stick — worth cleaning this area thoroughly during any pad change. It's also worth knowing that the clearance between the pads and disc is designed to be extremely small, almost a light rub, rather than a generous gap.
