Genuine Mazda Front Brake Disc Dust Shield / Backing Plate – RH 270mm Sport • NC82-33-260A

Genuine Mazda NC82-33-260A Right-Hand Front Brake Disc Dust Shield / Backing Plate

Replacement Genuine Mazda right-hand front brake disc dust shield for Mazda MX-5 Mk2.5 NB-FL 1.8 Sport models fitted with the factory 270 mm front brake system.

This pressed-steel shield is fitted behind the right-hand front brake disc, between the front suspension upright and wheel-bearing assembly. It helps protect the brake disc, caliper, wheel bearing and surrounding components from stones, dirt, road debris and direct water spray.

The shield also separates the rotating brake disc from the surrounding upright and suspension components. Correct shape and alignment are important to maintain adequate clearance and prevent scraping or rubbing noises.

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

Important brake-size restriction: This shield is specifically designed for the factory larger-brake arrangement using 270 mm front discs. Standard-brake MX-5 NB and NB-FL models use different shields, so fitment should not be determined solely by model year or engine size.

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, allowing the shield to distort, loosen or contact the rotating brake disc.

Fitment advice: Confirm that the vehicle has the factory 270 mm front Sport brake arrangement before ordering. Standard-brake NB and NB-FL vehicles use different front shields. Measure the front brake-disc diameter or compare the original Mazda reference where the brake specification is uncertain.

Other items to consider: Inspect the left-hand dust shield, front brake discs, brake pads, calipers, wheel bearings, ABS sensor equipment and associated retaining hardware. Replace any 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, brake cleaner, wire brush and appropriate wheel-bearing removal and installation equipment.

Difficulty guide: DIY Difficulty: Advanced. The brake caliper and disc must be removed, and the shield is mounted behind the wheel-bearing assembly. Suitable bearing-removal equipment and careful handling of the ABS components are required.

Why Genuine Mazda? Genuine Mazda brake dust shields are formed to match the original front-upright mounting points, wheel-bearing centre and 270 mm brake-disc clearance. Correct dimensions help prevent contact with the rotating disc and maintain compatibility with the factory Sport brake assembly.

What’s in the box: One Genuine Mazda right-hand front brake disc dust shield / backing plate, part number NC82-33-260A.

Installation notes: Raise and support the vehicle safely, then remove the right-hand front brake caliper, carrier and brake disc in accordance with the applicable Mazda workshop procedure. Remove the wheel-bearing assembly carefully without damaging the upright or ABS equipment. Clean the mounting surfaces and fit the replacement shield in the original orientation. Reinstall the bearing and brake components to the applicable Mazda specifications, then rotate the hub and disc by hand to confirm that the shield does not contact the disc.
