RIDEX Rear Brake Pad Set – MX-5 Mk1 1.8 / Mk2 1.6 & 1.8 • 402B0405

RIDEX 402B0405 Rear Brake Pad Set – MX-5 Mk1 1.8 / Mk2 1.6 & 1.8

Replacement RIDEX rear brake-pad axle set for Mazda MX-5 Mk1/NA 1.8 and Mk2/NB / Mk2.5/NB-FL 1.6 or naturally aspirated 1.8 models.

The rear brake pads sit inside the rear brake calipers and clamp against the rotating brake discs when hydraulic pressure is applied. This friction slows the vehicle and also forms part of the rear braking system used in conjunction with the handbrake mechanism.

Important fitment restrictions: A different rear brake pad is required for Mk1/NA 1.6 models. MazSpec’s confirmed application data for this SKU covers naturally aspirated Mk2 1.6 and 1.8 variants up to 146 PS, so the Mk2.5 1.8 Turbo is excluded from this listing.

One set supplies the pads required for the complete rear axle. The pads incorporate acoustic wear-warning features and anti-squeak plates.

Fitment advice: MazSpec confirms this pad set for Mk1/NA 1.8 models and Mk2/NB / Mk2.5/NB-FL 1.6 and naturally aspirated 1.8 models. Compare the original pad profile, dimensions and relevant OE reference before installation, particularly on vehicles with non-standard or upgraded brake systems.

Common replacement reasons: Reduced friction-material thickness, uneven pad wear, squealing, grinding, vibration, contaminated friction material, corroded backing plates or replacement alongside worn rear brake discs.

Other items to consider: Inspect the rear brake discs, caliper slider pins, piston mechanisms, dust boots, handbrake operation, flexible brake hoses and brake-fluid condition. Rear discs should normally be replaced as an axle pair if worn below specification, heavily scored or badly corroded.

Useful tools / consumables: Trolley jack and axle stands or vehicle lift, wheel-removal tools, socket and spanner set, torque wrench, suitable rear-caliper piston retraction / wind-back tool, brake cleaner and approved brake lubricant for specified contact points.

Difficulty guide: DIY Difficulty: Moderate. Rear caliper piston retraction must be performed using the correct method, and the handbrake mechanism should be checked and adjusted as required after installation.

Why RIDEX? RIDEX brake components provide a cost-effective aftermarket servicing option manufactured to application-specific dimensions. This set is supplied as a complete rear-axle pad set with acoustic wear-warning and anti-squeak features.

What’s in the box: One complete RIDEX rear brake-pad axle set. Brake discs, calipers and installation consumables are not included unless physically present in the supplied package.

Installation notes: Support the vehicle securely and remove both rear wheels. Remove and support the rear calipers without allowing them to hang from the flexible brake hoses. Inspect the discs, pistons, sliders, dust boots and handbrake mechanism. Retract the rear caliper pistons using the correct tool and procedure, install the pads in the correct orientation and refit all components to the applicable tightening specifications. Operate the brake pedal until firm, check brake-fluid level and verify correct handbrake operation before driving. Bed the new pads in progressively.
