TRW Automotive AfterMarket GCH2617 Hand Brake Cable

The TRW GCH2617 is a premium hand‑brake cable designed for rear parking brake systems in a wide range of vehicles, most notably the BMW 3 Series (E46) and its derivatives. Manufactured by TRW Automotive AfterMarket, this component delivers reliable performance, precise actuation, and long‑term durability.

Key Features

• High‑strength steel construction ensures consistent tension and resistance to wear over thousands of cycles.
• Corrosion‑resistant coating protects the cable from moisture, road salts, and environmental contaminants.
• Designed for rear disc brake systems, providing smooth engagement and release.
• Compatible with both left and right handbrake assemblies in dual‑cable configurations.
• Precision engineered to match the original equipment specifications of TRW OEM parts, guaranteeing a seamless fit.

Compatibility Overview

The GCH2617 is specifically tailored for:

• BMW 3 Series (E46) – Limousine, Coupe, Touring, and Convertible models equipped with rear disc brakes.
• Other vehicles that use the same rear parking brake cable geometry, including certain Moto GCH2617 systems.

When selecting a replacement, always verify the vehicle’s year, model, and brake type to ensure optimal performance. The cable is available in both left‑handed and right‑handed variants, allowing for full compatibility with dual‑cable setups commonly found in modern rear parking brake systems.

Installation Highlights

Installing the TRW GCH2617 involves:

1. Removal of the old cable – Carefully detach the existing handbrake cable from the lever and the rear brake assembly, noting any tension or alignment marks.
2. Preparation of the new cable – Inspect for straightness, ensure the protective coating is intact, and verify that the cable length matches the vehicle’s specifications.
3. Attachment to the handbrake lever – Secure the cable to the lever using the supplied hardware, maintaining proper tension as per manufacturer guidelines.
4. Routing through the chassis – Guide the cable along its designated path, avoiding sharp bends or excessive friction points that could compromise longevity.
5. Connection to the rear brake assembly – Attach the cable to the parking brake actuator on each rear wheel, ensuring a snug fit and correct alignment.
6. Tension adjustment – Fine‑tune the cable tension so that the handbrake lever operates smoothly while still engaging the rear brakes fully when pulled.
7. Functional testing – Verify that the handbrake engages and releases correctly, checking for any binding or excessive play.

Performance Benefits

The TRW GCH2617 delivers several advantages over generic aftermarket cables:

• Consistent braking force – The steel core maintains tension, ensuring that the parking brake applies uniform pressure across both rear wheels.
• Reduced maintenance – The corrosion‑resistant coating minimizes rust and wear, extending service intervals.
• Improved safety – Reliable actuation of the parking brake reduces the risk of unintended vehicle movement when parked.
• Compatibility with OEM systems – Matching the original design specifications guarantees that the cable functions exactly as intended by the vehicle manufacturer.

Maintenance Tips

To preserve optimal performance, consider the following routine checks:

• Inspect the cable for visible wear or fraying every 12–18 months.
• Check the tension settings after any major repair or when noticing a change in lever feel.
• Ensure that the cable routing remains free of debris and that no sharp edges are causing abrasion.
• Apply a light coat of lubricant to the cable’s internal surfaces if recommended by the vehicle manufacturer, but avoid over‑lubrication which can attract dirt.
