RIDEX 402B0590 Rear Brake Pad Set

Replacement RIDEX rear brake-pad set for Mazda MX-5 Mk3/NC, Mk3.5/NC-FL, Mk3.75/NC-FL2 and Mk4/ND/RF models listed in the compatibility table.

The brake pads fit inside the rear brake calipers and clamp against the rear brake discs when hydraulic pressure is applied. The resulting friction converts vehicle movement into heat and slows the vehicle.

This is a complete axle set containing sufficient pads for both rear calipers. The pads include anti-squeak plates and an acoustic wear-warning feature.

Common reasons for replacement include reduced friction-material thickness, brake noise, uneven wear, scoring, contamination, corrosion, deterioration of the backing plates or replacement alongside worn rear brake discs.

Fitment advice: These pads are used across the listed Mazda MX-5 NC and ND/RF rear brake applications, together with related Fiat and Abarth 124 Spider systems. Match the original pad shape, 99.3 × 44.5 × 14.6 mm dimensions, WVA 24298 and OE reference before installation, particularly where the braking system has been modified.

Other items to consider: When replacing the rear pads, inspect the rear brake discs, caliper pistons, slider pins, dust boots, pad fitting hardware, flexible brake hoses and brake-fluid condition. Replace scored, corroded or undersized discs as an axle pair.

Useful tools / consumables: Vehicle lift or trolley jack and axle stands, wheel-removal tools, socket and spanner set, torque wrench, rear caliper piston wind-back tool, brake cleaner, slider-pin lubricant and suitable protective gloves and eyewear.

Difficulty guide: DIY Difficulty: Moderate. Rear pad replacement requires correct retraction or rotation of the parking-brake caliper pistons and careful inspection of the caliper sliders and brake discs.

Why RIDEX? RIDEX braking components provide a cost-effective aftermarket servicing option manufactured to application-specific dimensions. These pads include anti-squeak plates and an acoustic wear-warning feature to support consistent braking and service indication.

What’s in the box: One complete RIDEX rear brake-pad set for both rear calipers. Brake discs, caliper slider components, pad-retaining hardware and fitting consumables are not included unless physically present in the supplied package.

Installation notes: Support the vehicle securely and remove both rear wheels. Release the parking brake and confirm the correct procedure for retracting the rear caliper pistons. Remove the calipers and support them without allowing their weight to hang from the flexible hoses. Inspect the discs, slider pins, piston boots and pad-contact surfaces. Clean the caliper carriers and apply suitable brake lubricant only to the approved sliding and contact points, keeping all lubricant away from the friction material and disc surfaces. Retract or wind back the pistons using the appropriate tool, install the new pads in the correct orientation and refit the calipers using the applicable tightening specifications. Operate the brake pedal until firm, restore and test the parking brake, then bed in the pads according to the brake manufacturer’s instructions.
