The TRW Automotive AfterMarket DF2703 Brake Disc is a high‑performance, OEM‑grade replacement brake disc designed for rear applications on a wide range of Mazda and Ford vehicles. Manufactured by TRW, a leader in automotive braking systems, this disc delivers reliable stopping power, durability, and consistent performance under demanding driving conditions.

Key Features

• OEM Compatibility: Engineered to match the exact specifications of the original equipment brake discs for Mazda MX‑5 (NA & NB), Mazda 323 series (C IV, F IV, S IV), and Ford models that share the same rear braking architecture.
• High‑Quality Material: Made from a premium cast iron alloy with a hardened surface layer. This composition provides excellent heat dissipation, wear resistance, and long service life.
• Precision Machining: Each disc is machined to strict tolerances, ensuring perfect fitment on the hub, accurate rotor thickness, and optimal contact with brake pads.
• Full Disc Design: The disc features a solid construction without venting or perforations, which enhances heat transfer during heavy braking and reduces the risk of brake fade.
• Surface Finish: The outer surface is finished to a smooth profile that promotes even pad wear and consistent braking performance across the entire contact area.
• Corrosion Protection: A protective coating resists rust and corrosion, extending the disc’s lifespan in various climates and road conditions.

Vehicle Compatibility

The DF2703 is specifically designed for rear brake systems on the following models:

• Mazda MX‑5 (NA & NB)
• Mazda 323 series – C IV, F IV, S IV
• Mazda MX‑3 (EC)
• Ford vehicles that share the same rear brake architecture as the above Mazda models.

These discs are available in both single and dual configurations to accommodate various vehicle setups. The dimensions match OEM specifications, ensuring a seamless installation experience without the need for additional modifications.

Installation Guidelines

1. Remove Existing Disc: Carefully detach the current brake disc from the hub using appropriate tools and ensure no debris remains on the mounting surface.
2. Inspect Hub Surface: Clean the hub with a solvent to remove grease, rust, or old sealant. Verify that the hub is free of damage or warping.
3. Apply Anti‑Seize Compound: Apply a thin layer of anti‑seize compound on the hub surface to prevent future seizure and ease removal during maintenance.
4. Mount Disc: Align the new DF2703 disc with the hub, ensuring that it sits flush against the mounting flange. Use a torque wrench to tighten the mounting bolts to the manufacturer’s specified torque value.
5. Reinstall Brake Pads: Install compatible brake pads and adjust the caliper as necessary to achieve proper pad clearance.
6. Brake Fluid Check: Verify that the brake fluid level is correct and that there are no leaks in the system.
7. Test Drive: Perform a short test drive at low speed, gradually applying brakes to confirm smooth operation and adequate stopping power.

Performance Benefits

• Consistent Stopping Power: The solid construction and high‑quality material ensure reliable braking performance even under repeated heavy use.
• Heat Management: Excellent thermal conductivity helps dissipate heat quickly, reducing the risk of brake fade during spirited driving or long descents.
• Longevity: The hardened surface and corrosion protection extend the disc’s service life, providing value over many miles.
• Low Maintenance: Designed for minimal wear on pads and calipers, reducing overall maintenance costs.

Maintenance Tips

• Inspect brake discs regularly for signs of glazing, scoring, or uneven wear. Replace if any irregularities are detected.
• Keep the disc surface clean by wiping with a mild solvent during routine maintenance to prevent contamination that could affect braking performance.
• Avoid driving on wet roads at high speeds without proper brake pad contact; this can lead to premature disc wear.
