Over time and many braking cycles, this type of pin can lose its secure fit due to heat, corrosion, wear or damage - especially in older vehicles which may have high mileage or have been exposed to the elements.
If the pin is worn, bent or missing, brake pad alignment or hand-brake performance may be compromised, which can lead to brake noise, uneven wear, or reduced pad life.
During any rear brake service, pad change, or brake assembly overhaul, replacing worn retaining/locking hardware is smart preventative maintenance and helps avoid bigger issues later.

When to replace it:
• Whenever you disassemble the rear disc brake caliper or hand-brake related components.
• At the time of pad replacement, hardware refresh, or when performing a restoration or full brake rebuild on a classic Porsche.
• If you notice symptoms such as pad movement, rattle, hand-brake dragging or uneven pad/disc wear at the rear.
• Especially on vintage Porsche models, maintaining original specification hardware like this helps preserve correct braking feel and authenticity.
