Quinton Hazell BDC4747 Rear Brake Disc Pair

Replacement Quinton Hazell rear brake disc pair for Mazda MX-5 MK1/NA 1.8 and MK2/NB/NB-FL 1.6 and 1.8 petrol models listed in the compatibility table.

The rear brake discs provide the friction surfaces for the rear brake pads, allowing the braking system to slow the vehicle as the calipers clamp the pads against the rotating discs. BDC4747 is designed as an aftermarket replacement for the original components.

These are solid rear brake discs measuring 250 mm in diameter and 9 mm thick. Two discs are required per vehicle and this listing supplies a pair for the complete rear axle.

Replacement may be required if the existing discs are worn below minimum thickness, heavily corroded, scored, damaged or contributing to brake judder or uneven braking. Replacing both rear discs together helps maintain consistent braking performance across the axle.
