Technical Specifications

Performance Highlights

The TRW DF7928 is engineered to maintain consistent braking performance even under high‑temperature scenarios. Its vented design facilitates rapid heat dissipation, reducing the risk of brake fade during aggressive driving or heavy load conditions. The graphite reinforcement ensures dimensional stability, preventing distortion that could compromise pad contact.

Installation Guide

1. Preparation: Ensure the vehicle is securely lifted and supported on jack stands. Remove the rear wheel to access the brake assembly.
2. Remove Existing Disc: Loosen and remove the caliper bolts, then carefully detach the caliper. Slide out the old disc from the hub.
3. Install New Disc: Place the TRW DF7928 onto the hub, aligning it with the mounting surface. Reattach the caliper, ensuring proper pad alignment.
4. Tightening Sequence: Tighten all bolts in a star pattern to the manufacturer’s torque specifications.
5. Final Checks: Verify that the disc is flush against the hub and that there are no obstructions. Reinstall the wheel, lower the vehicle, and perform a brake test at low speed.

Maintenance Tips

• Inspect the disc surface for cracks or uneven wear every 10,000 km.
• Replace brake pads when pad thickness falls below 3 mm to avoid metal‑to‑metal contact.
• Avoid driving on wet surfaces at high speeds until the brakes have cooled to prevent hydroplaning.
