Genuine Mazda Front Brake Disc Dust Shield / Backing Plate – RH • N243-33-261

Genuine Mazda N243-33-261 Right-Hand Front Brake Disc Dust Shield / Backing Plate

Replacement Genuine Mazda right-hand front brake disc dust shield for Mazda MX-5 Mk4 ND and RF models.

This pressed-metal shield is positioned behind the right-hand front brake disc. It helps protect the disc, hub and surrounding braking components from stones, dirt, debris and direct road-water spray.

The shield also provides separation between the rotating brake disc and the surrounding hub and suspension components. Correct positioning and clearance are important to prevent the shield contacting the disc during wheel rotation.

Brake dust shields are continuously exposed to moisture, road salt, debris and repeated brake-temperature cycles. Over time, corrosion can weaken the outer edge or mounting area, causing the shield to distort, loosen or rub against the rotating brake disc.

This is a handed component for the right-hand front side only. One right-hand shield is fitted per vehicle, and this listing supplies one Genuine Mazda shield.

Fitment advice: This listing is for the right-hand front shield. Confirm the required side before ordering. The corresponding left-hand front shield is Mazda part number N243-33-271. Check the original hub, brake and upright arrangement where modified brakes or replacement suspension components have been installed.

Other items to consider: Inspect the left-hand shield, front brake discs, brake pads, calipers, wheel hubs, bearings and associated retaining hardware. Replace any fastener or component that is heavily corroded, damaged or unsuitable for reuse.

Useful tools / consumables: Suitable socket and spanner set, breaker bar, calibrated torque wrench, penetrating fluid, wire brush, brake cleaner and appropriate hub-removal equipment where required.

Difficulty guide: DIY Difficulty: Advanced. The brake caliper and disc must be removed, and access to the shield mounting points may require further hub disassembly. The vehicle must be raised and supported safely before work begins.

Why Genuine Mazda? Genuine Mazda brake dust shields are formed to match the original mounting points, hub centre, brake-disc clearance and surrounding suspension geometry. Correct dimensions help prevent contact with the rotating disc and maintain compatibility with the original brake and hub assembly.

Installation notes: Raise and support the vehicle safely, then remove the right-hand front brake caliper and disc in accordance with the applicable Mazda workshop procedure. Remove any additional hub components required for access without damaging the wheel bearing or ABS equipment. Clean the mounting area and fit the replacement shield in the original orientation. Confirm that it sits squarely and is not distorted. Reassemble all components to the applicable Mazda specifications, then rotate the hub and disc by hand to confirm that there is no contact with the shield.
