Land Rover Discovery Sport Brake Discs: Specs, Fitment & Wear Symptoms

On the Discovery Sport, a persistent vibration on related models has genuinely been traced to backwards-fitted pads rather than genuinely warped discs.

OEM Part Number: LR059122

Accuracy note: genuinely worth knowing — owners have directly reported confusion between two front disc sizes for this model (325mm and 349mm), depending specifically on engine power output, with the larger size fitted to higher-output petrol variants for extra stopping power. Measuring your actual disc is the reliable way to confirm which applies if you're unsure.

Front disc, standard/diesel variants	Land Rover OEM: LR059122 (also shared with Range Rover Evoque) — 325mm diameter
Front disc, higher-output petrol variants	349mm diameter, 30mm thickness — a genuinely different, larger specification
Rear disc, all variants	Land Rover OEM: LR161918 or LR161919 — 300mm diameter
Front brake disc and caliper assembly (2015+, various engines)	Land Rover OEM: LR161907

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 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

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.
