some one was talking to me today about my ST and asked what the brakes were like, I replied "not to bad actually" his reply was, they should be,, the calipers are same as a sapph cosworth??? is this right?? I dont think so but could not say anything back as I was not 100%?

 

If its a Mark 2 then they are wrong. The brakes on the ST24/ST200 are atrocious and the best thing you can do with them is do a Mk3 upgrade like a lot of us have.

 

is a straight forward replacement?

 

Yep mk3 calipers and pads with 3mm spacers and ST170 discs. Upgrades from 278mm to 300mm, couple this with braided lines and you will suddenly see how crap the standard brakes really ae!!!!!!

 

You can fit ST24 pads in Escort cosworth calipers, no idea if they are the same caliper though.

 

when i changed the discs to drilled and groved on my v6 mondeo si , i had the calipers off a scorpio fitted to mine as when i got the two sets for the front the books said they were both a different shape so i took my old pad with me and matched it to the scopio caliper ,but since chaging them to drtilled and groved my brakes are a lot lot bettter than they was before so i was baffled with this one

 

Is it any mk 3 callipers I need to do the upgrade

 

all mk3 calipers are the same.
