Genuine Mazda Front Brake Disc Dust Cover / Backing Plate – Right Hand
Replacement Genuine Mazda right-hand front brake disc dust cover for all Mazda MX-5 Mk3, Mk3.5 and Mk3.75 NC models with 1.8- or 2.0-litre petrol engines.
The backing plate mounts behind the right-hand front brake disc, between the wheel bearing or hub assembly and the steering knuckle. It shields the inner braking surface and surrounding caliper area from direct exposure to road debris, standing water and contamination.
A heavily corroded or distorted plate can contact the rotating brake disc and produce scraping or metallic rubbing noises. Severe corrosion can also cause sections of the plate to break away from the mounting area.
One right-hand plate is fitted per vehicle, and this listing supplies one Genuine Mazda backing plate. The corresponding left-hand plate is supplied separately under Mazda reference NF47-33-271B.
Side identification: Right hand refers to the vehicle’s right side when seated in the vehicle facing forwards. On a UK right-hand-drive vehicle, this is the offside or driver’s side.

- Backing plate contacting the rotating brake disc

- Front wheel-bearing or hub replacement

Fitment advice: NF47-33-261B is the right-hand plate. Confirm the required side before ordering. The matching left-hand front backing plate uses Mazda reference NF47-33-271B.
Brake-package advice: The plate is listed across the complete MX-5 NC range, including 1.8, 2.0 and 2.0 Sport variants. No separate standard-brake or Sport-brake restriction was confirmed for this reference.
Replacement advice: Inspect the corresponding wheel bearing or hub, steering knuckle and mounting surfaces while dismantled. A new backing plate will not correct wheel-bearing play, a distorted knuckle or excessive brake-disc runout.
Brake inspection advice: Check the brake disc for scoring, corrosion and minimum thickness. Inspect the brake pads, caliper slider pins, piston dust boot, flexible brake hose and ABS sensor wiring while the assembly is accessible.
Other items to consider: Consider replacing the wheel bearing or hub assembly if it is noisy, rough or has measurable play. Inspect the corresponding left-hand backing plate, as both sides are commonly exposed to similar corrosion.
Useful tools / consumables: Vehicle lifting equipment, axle stands, socket set, breaker bar, calibrated torque wrench, hub-removal tools, penetrating fluid, wire brush and brake cleaner.
Difficulty guide: DIY Difficulty: Moderate to Advanced. Installation requires removal of the front brake components and wheel hub or bearing assembly to position the plate correctly against the steering knuckle.
Why Genuine Mazda? Genuine Mazda backing plates match the original mounting-hole positions, disc clearance, pressed profile and corrosion-resistant finish. Correct geometry helps prevent contact with the rotating disc while maintaining protection around the inner braking surface.
What’s in the box: One Genuine Mazda right-hand front brake disc dust cover / backing plate, part number NF47-33-261B.
Installation notes: Raise and support the vehicle safely, remove the front wheel, brake caliper and brake disc, then remove the wheel hub or bearing assembly following the applicable Mazda procedure. Remove the original backing plate and clean the steering-knuckle mounting face. Install the new plate in the correct orientation and ensure that it sits flat without contacting the brake disc. Refit the hub, brake components and wheel using the specified tightening procedures. Before driving, operate the brake pedal to restore normal pad position and confirm that the disc rotates without contacting the plate.
