OEM Part Number: LR059122 (genuine front disc — confirm via VIN) — aftermarket front discs Brembo 09.A427.11 / TRW DF4850S

Accuracy note: Covers the Land Rover Discovery Sport (2014-) as listed in the UK aftermarket catalogues. Front brake discs are sold by diameter and thickness, and most models have two or three disc sizes depending on engine, brake size and trim — a 278 mm disc will not fit a car built with 300 mm brakes, so the caliper carrier and the disc must match. The references below are UK aftermarket catalogue listings for this generation, labelled by brand with diameter x thickness in mm; genuine numbers are shown only where a listing quotes one. Measure the old disc or check the brake size against your VIN before ordering, replace discs in pairs with new pads, and scrap any disc at or below its minimum thickness.

Land Rover Discovery Sport Brake Discs: The Part That Pads Depend On

On the Land Rover Discovery Sport, 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.

Land Rover Discovery Sport 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 Discovery Sport typically use bigger discs than standard versions to handle the additional heat generated by more aggressive braking.

A Genuinely Useful Piece of Context Worth Knowing About Brake Vibration — Land Rover Discovery Sport Brake Discs

If a vibration under braking has been diagnosed as warped discs, this is genuinely worth knowing: documented cases on related Land Rover models describe a persistent vibration actually traced to brake pads fitted backwards rather than genuinely warped discs, since pads are directional — worth confirming this before assuming the discs themselves are at fault.

A genuinely alarming, honest account worth knowing: documented cases describe discs warping repeatedly on relatively young cars, with dealers sometimes unable to explain why or guarantee it won't recur even after replacement.

It's also genuinely worth knowing a useful alternative cause worth checking: an axle seal leaking oil or grease directly onto the disc surface can produce vibration symptoms very similar to genuinely warped discs.
