Hello,
Can you help? What size is the allen key used to split the front brake caliper of a Ford Fiesta MK3 ?

I may be wrong and thinking of something entirely different but I think it's
7mm. Not a standard size. If a 6 is too small and an 8 is too big then that'll tell you.I got mine from a bicycle repair shop when out in the middle of nowhere fixing a car for a friend.

Thanks for that. It is definitely not a 6mm size key, I have that size and it is too small.

The 7mm allen key is known as a "brake caliper" type. Almost all car brake calipers use this size, which is often only obtainable from car accessory places, as almost nothing other than brake calipers use this size.

A 7mm hex key is commonly known in engineering, as a non-preferred size, which is why it's usually not included in hex key sets. IME the easiest, and certain way to buy one is to get it from a small tool stockist. Yellow pages should find the nearest one. Mike.
