The EBC DP21452 is a GreenStuff front pad set, sized for the 2001–2003 Mazda MX-5 Miata 1.8 with sports suspension. EBC's GreenStuff pads are aimed at lightweight vehicles and hot hatches, with up to 15% improvement in braking over original pads and low dust. The nominal friction coefficient for the compound is 0.55. That makes it a street-first upgrade for a spirited NB Miata, not a track pad. Buyers searching for a 01-03 Miata 1.8 sport suspension front brake pad, a low-dust NB Miata street pad, or a quiet GreenStuff replacement will find this set matches those needs. The pads are ECE R90 approved, and the lowest dust formulation keeps wheels cleaner for longer. The pads are shimmed, chamfered, and slotted for quiet running.
Owners on user forums note that the NB's sport brake package was optional for 2001–02 and standard on 2003–05 US cars, so confirm your brake package before ordering. For installation, owners on user forums describe a straightforward front job: loosen the lug nuts while the car is still on the ground, jack the front from under the crossmember, and grease the backing plates before snapping on the wear indicators. A caliper spreader or C-clamp is needed to retract the piston, and an old pad helps protect the piston face. The Brake-In coating is designed to speed up the bed-in period. Bed the pads with progressive stops rather than hard stops to avoid glazing.
The manufacturer advises not to refit shims or insulators from original pads unless the pad packaging specifically instructs it.
Owners on user forums report that the sport brake package was optional for 2001–02 and standard on 2003–05 US cars, and the sport brake system uses different front hardware than standard. Because the catalog listing for this set specifies sports suspension trims, verify your brake package before ordering.
The manufacturer's Brake-In coating is intended to shorten the bed-in period. For EBC's noiseless pad range, the manufacturer indicates a break-in of roughly 200–500 miles, so expect some initial adjustment in feel and noise.
Front pad changes on the NB are a manageable weekend job for a home mechanic. Owners on user forums recommend cleaning the rotors and checking that the caliper slide pins and sliders move freely before assembly, and applying brake grease only to the slider pins and pad-ear contact points, not the pad faces or rotor. Keep the master cylinder cap in mind: as the piston is pushed back, fluid level rises, so check it before reinstalling the cap. Torque the wheel lugs to spec and re-check after the first few stops.
