Removing clip (brake servo/pedal) RENAULT MASTER III Box (FV)

Based on your description, it sounds like you're dealing with a challenging pin removal issue on your Ford Transit MK3. Let me help you with this frustrating situation.

For Ford Transit vehicles, especially the MK3 model, there are several types of pins and fasteners that can be particularly difficult to remove. The "headless pin" you're describing is likely one of the plastic snap-fit pins commonly used in these vehicles.

These two-part plastic snap-fit pins require a specific technique to remove properly. First, you need to pull out the center pin (which serves as a locking mechanism) using a small flat screwdriver or wedge tool. This creates space for the outer part to contract when you're pulling it out of the hole in the body.

For the outer frame of the pin, try pulling on the thicker area rather than where the center-pin-removal-slot is located. You might need to insert a small flat screwdriver between the panel and the rim of the outer pin and carefully pry it until it pops out.

If you're dealing with pins that have tiny tangs on either side (common in Ford Transit electrical connections), pushing a small flat screwdriver into the plastic plug on either side of the pin should release it. This technique works particularly well for light socket pins.

For riveted components, you'll need to drill out the rivets carefully. As seen in some Transit modifications, removing riveted parts (like bulkheads) requires drilling out the rivets completely before the component can be freed.

If you're still having trouble after trying these methods, you might want to consider visiting a specialized garage that works on Ford Transit vehicles, as they would have the proper tools and experience to help with difficult fasteners without causing damage to your van.
