Designed with precision machining and advanced material composition, this component delivers reliable stopping power while maintaining durability under demanding driving conditions.

Key Features

• Material Excellence: Constructed from a premium alloy that offers superior heat dissipation and resistance to brake fade. The disc’s composition ensures consistent performance even during prolonged braking sessions.
• Optimized Geometry: Features a 265mm diameter with a 10mm thickness, striking an ideal balance between weight, strength, and thermal capacity. The design includes a full disc (plein) configuration for uniform braking force distribution.
• Compatibility: Specifically engineered to fit the rear wheel assemblies of Renault Avantime, Espace III, and related models. The disc’s mounting interface aligns with standard hub dimensions, ensuring seamless installation.
• Surface Finish: Finished with a smooth, polished surface that promotes optimal brake pad contact. This finish reduces noise and vibration during operation while enhancing overall braking efficiency.
• Longevity: The robust construction resists corrosion and wear, extending the service life of the disc even in harsh environmental conditions.

Installation Overview

Installing the TRW DF4546 involves removing the existing rear brake assembly, aligning the new disc with the hub flange, and securing it with the supplied mounting hardware. The disc’s design allows for straightforward torque application, ensuring a secure fit without compromising wheel alignment.

Step‑by‑Step Guide

1. Lift the vehicle and support it securely on jack stands.
2. Remove the rear wheel and brake caliper assembly.
3. Detach any retaining clips or bolts that hold the current disc in place.
4. Position the new TRW DF4546 onto the hub flange, aligning the mounting holes precisely.
5. Screw in the mounting bolts to the specified torque setting.
6. Reinstall the brake caliper and wheel, then lower the vehicle.
7. Perform a brake test to confirm proper operation.
