Hi everyone. Without sounding like a numpty (which I am well aware I'll probably sound like). I've just noticed this gap on the front brakes of my Fabia MK4. Can someone tell me what/if anything is missing? It looks like something is meant to clip in?

If by "gap" you mean what I've marked in green on the image below, that is perfectly normal for the design of front disc-brake caliper commonly fitted to VW Group cars (my 2009 Skoda Roomster has a similar front-brake caliper design)

and what you can see through the 'gap' (arrowed in red) is the back of a disk pad and (I believe) an anti-rattle spring.

This photo is of a complete front-brake caliper removed from a Skoda Fabia Mk 4 and I've marked the 'gap' in yellow.

Ah perfect - thanks!

It's the first time I've noticed it to be honest and I've had the car for 2 years. It must've just been the way the alloys were positioned when I was cleaning the car yesterday which gave me more visibility than usual.

Thanks for the detailed reply too - much appreciated
