Mk3 Focus TDCI Zetec S - Brake Disc sizes

[ColonelApeman]

Hello! 

I just wanted to see what the standard diameter of the front brake discs are. I’ve tried strolling through the forum but can only find mark 2 details. 

Ive got 18” alloys (optional extra w/ ford) I’ve tried having a rough measurement (using two straight edges and a tape measure) and think the 278mm ones would be a rough estimate. 

Any clarification would be awesome!

 

thanks

I'm fairly sure the mk3 Zetec S got 300mm discs front and disc rear even on the 1.6.  Measuring should guarantee it though, I don't see that you could be 20mm out?

I believe if you have rear discs it will be 300mm front, 270mm rear

Drums you will have 278mm at the front

Thanks for this, I’ve got discs at the back and all.
