As i sed b4 a while ago, i have sum sapph cossie calipers, but just wanted to ask all the experts out there just a few more Qs to put me mind at rest

I now know that I'd need a braided hose kit for a mk3 fiesta, and that the rear lines can b swapped over aswell BUT....

On reading up the info on brake conversions to cossie types, I know the hubs would need to be drilled out to 12mm, and then with sum washers the lot should go on fine.

Me uncle was saying today the servos would all need to be uprated and such like. Is this true? If i just had the setup fitted would the brakes work as they're supposed to?

Just the whole reason i'm uprating me brakes is for a 2 litre conversion in the future.

Any advice appreciated

My pedal went spongey when adding the RS2000 rear discs - but that's because of the extra capacity the braking system had. I then changed hte engine to a 1.9 and the sponge went!

Anyway - I'd say if you're keeping the rears the same (which I'd recommend anyway unless you're going for a milder setup like the RS2000 rear disc/drum setup) then the servo will be fine.

If you're really not happy with it then change the servo at the same time as the engine conversion. Seems to make sense to me.

Hub drilling is only necessary on ST170 brake conversions as my friend has just done his on his Escort. I'm not an expert as your car is a mk3.5 but I think they're the same as the mk3 and mine needed NO drilling of the hubs, merely a 5mm spacer to move the caliper out to the correct position for the Fiesta hubs (this is why it's such a common conversion - because it's really easy and not that daunting!).

My answers for anything else are the same as in the other post.

Cheers,

Andy

ah ok - would i definately need to use a spacer for the hubs? as i have 17s on it at the mo, and the alloy outer edge is pretty much level with the edge of the arch as it is - and if it goes past the arch, it'll fail an MOT

you need to use spacers to space the bracket out. But this will not space your wheel out. The wheels will actually be brought in a bit as the esc cos discs are for a diff offset and i found my wheels came in so are about a 1mm away from the suspension now and clear the arch easily so have actaully help elimate scrubbage at the front
