Fabia X Reg 1.4 FSIII calliper pins

Hi.

Firstly - thank you to everyone who contributes as I have had so much help fixing my sons X reg Fabia 1.4.

A while ago, I replaced the front pads and discs, no real drames except that the threaded holes in the calliper carriers (all part of the hub) that the calliper pins bolt in to were a little worn.

I am getting ready to fit new front lower arms and bushes - using the guide on here - and want to use a thread kit to reapir the threads.

My question is, does anyone know what size the thread is on the calliper pins? The callipers are the FSIII type

Thanks in advance

Matthew
