Genuine Mazda N067-26-261 Rear Brake Disc Dust Shield / Backing Plate
Replacement Genuine Mazda rear brake disc dust shield for Mazda MX-5 Mk2.5 NB-FL Sport and compatible larger-brake models.
This pressed-steel shield is installed behind the rear brake disc and wheel hub. It helps protect the brake disc, caliper, parking-brake components and surrounding rear hub assembly from stones, dirt, road debris and direct water spray.
The shield also separates the rotating brake disc from surrounding suspension and hub components. Correct shape and positioning are important to maintain adequate clearance and prevent scraping or rubbing noises.
This part is designed for the larger factory rear brake arrangement fitted to Mk2.5 Sport models. It is different from the rear shield used with the standard brake setup and should not be selected solely by vehicle generation.
The same component fits either the left- or right-hand rear side. There are two shields fitted per vehicle, and this listing supplies one Genuine Mazda shield. Select a quantity of two when replacing both sides.
Rear brake shields are continuously exposed to moisture, road salt, debris and repeated brake-temperature cycles. Over time, corrosion can weaken the outer edge or central mounting area, allowing the shield to distort, loosen or contact the rotating brake disc.

Important brake-system distinction: This shield is intended for the larger rear brake arrangement used on Sport-suspension models. Standard-brake Mk1 and Mk2/Mk2.5 vehicles generally use a different rear shield. Confirm the original brake-disc diameter and dust-shield arrangement before ordering.
Possible reasons for replacement:
- Heavy corrosion or perforation
- Outer edge rubbing against the brake disc
- Scraping or rattling from a rear wheel
- Shield bent during previous brake or hub work
- Central mounting area weakened by corrosion
- Damage during wheel-bearing or hub removal
- Restoration of the rear brake and hub assembly
Fitment advice: Confirm that the vehicle is fitted with the larger factory Sport rear brake arrangement before ordering. Do not identify this component solely by model year, because standard and Sport brake packages use different rear shields. Measure the rear brake disc or compare the original Mazda part number where the brake specification is uncertain.
Other items to consider: Inspect the shield on the opposite side, rear brake discs, pads, calipers, parking-brake components, wheel bearings, hubs and retaining hardware. Replace any component that is heavily corroded, damaged or unsuitable for reuse.
Useful tools / consumables: Suitable socket and spanner set, breaker bar, hub puller, hydraulic press or appropriate bearing equipment, circlip pliers, calibrated torque wrench, penetrating fluid, brake cleaner and corrosion protection for exposed surrounding metal.
Difficulty guide: DIY Difficulty: Advanced. The rear brake caliper and disc must be removed, and the wheel-hub and bearing assembly must normally be dismantled to access the shield. Suitable pressing and bearing-support equipment may be required.
Why Genuine Mazda? Genuine Mazda brake dust shields are pressed to match the original hub centre, brake-disc diameter, caliper clearance and rear-upright mounting arrangement. Correct dimensions help prevent contact with the rotating disc and maintain compatibility with the factory larger-brake assembly.
What’s in the box: One Genuine Mazda rear brake disc dust shield / backing plate, part number N067-26-261.
Installation notes: Raise and support the vehicle safely, then remove the applicable rear brake caliper, disc and hub assembly in accordance with the Mazda workshop procedure. Remove the original shield and clean the rear-upright mounting area thoroughly. Fit the replacement shield in the correct orientation and confirm that it sits squarely without distortion. Reinstall the hub and bearing using suitable equipment, replace any single-use retaining parts and tighten all hardware to the applicable Mazda specifications. Rotate the hub and disc before refitting the wheel to confirm that the shield does not contact the disc.
