The hand-brake expander bow is a small but vital component in the parking-brake system. When it becomes worn, bent or corroded, you may experience:
• Less holding force, vehicle may roll despite hand-brake applied
• Hand-brake shoes not fully engaging or fully releasing, leading to drag or overheating
• Uneven parking-brake performance between rear wheels
• Increased wear on cables, shoes, or other components due to mis-actuation
Replacing this bow restores correct geometry, smooth release and reliable holding - ensuring safety and preserving the value of your classic Porsche.
When to replace:
• Hand-brake lever needs excessive travel to hold the vehicle
• Original bow is bent, corroded or missing
• Parking-brake shoes were replaced or the mechanism was disassembled during service
• You’re restoring or maintaining a high-value classic and want all brake components to be correct specification
