New large disc conversion

[dar...@siepka.me.uk]

I have worked out a large disc conversion for 2+2 and saloon using recent model parts.you need 15" or larger wheels to fit the 280mm discs!!

The conversion is very simple, needing only two modifications!.

Parts needed.
Discs
Adc1280/dsk3118 or ndb1906.
These are ford ecosport 1.5d 2013 on.

Or you can use nbd207,
these are ford sierra/escort cosworth 4x4, note must be 4x4 as they only fitted these to that model.

Calipers
I used
2007 volvo s40 300mm.
But these calipers are also fitted to volvo v70, s80, s60 and c70, also ford focus mk3(11-), some mk2(05-11) and cmax.

BUT they must be from the 300mm disc models!!!
Do NOT get 278mm calipers as they won't work. The caliper mounting has 300 cast into it for identification.

How to fit.
All that is needed is to drill out the holes in the hub to 12.2mm to clear the caliper bolts which are 12mm(the old fiesta are 10mm)
Thats it!hose fits as normal, discs go straight on and with the hole opened so do the calipers.
Note, if you use the cosworth disc you need a 5-6mm spacer between the caliper and hub lug to correct the disc offset.

As usual, use of this information comes with no warranties or liability.
Please check your wheels and other clearance beforehand.

Enjoy and stay safe

Surprising (or maybe not, due to parts OEM parts suppliers making parts as ‘stock’ as possible?). I treated our Ford Ka+ (5-door Ka made in India) to new discs/pads last year. Most of the parts on the car are ex-Fiesta, so when I enquired about replacement parts I was shocked to find Ka+ Pads at £150 a pair, discs similar price (even unknown brands from factors). Some online digging around found the parts were indeed the same dimensions as the fiesta ones, and Ferodo discs/pads at £68 total were used. I suspect the cost from Main dealer including fitting (which took me 45 mins) would be close to £800?

Thanks Darren, Useful info.
I used the Sierra Cosworth 4x4 discs on my 2+2 until i upgraded to Wilwood
setup.
But, i used Escort RS Turbo calipers and brackets and i had to weld up the 2
caliper carrier mounting holes and redrill them at a different spacing.
Was a bit dubious about the welding on the caliper so i had a proper
engineering company do it.

This sounds much easier.
My setup is now on my Saloon so i may swap out the calipers with the ones
you suggest.

Thanks again,

Jim

Great work Darren. How did you manage to work it out!

It took a fair few hours browsing the brake disc catalog and photos of hundreds of brake calipers to narrow it down .

I had a cosworth disc from years back laying about to measure up.

I have cougar V6 discs (also 280mm ) on my saloon but the caliper is a mix of xr4x4 and original fiesta as well as a adaptor plate. Those calipers are getting rare these days so I wanted a recent model solution which turned out fairly smart .

I will post the details of the new version of my rear disc conversion soon once I finalize the mounting plate for caliper and the cable fitting on the actuator( yes I am fitting electric handbrake too!)

I fitted the billet four pot kit from hispec last year. Quite pricey but excellent quality and very light compared to standard calipers

Well done Darren!

This looks like a brilliant solution. And easier than the Peugeot option you made earlier.

Thanks for that.

Rolf

Ps: how is the 2+2/4x4 getting on?

Hi Bob, A pair of hi spec calipers came with my saloon, i'm fitting this week, can i ask did you need to change the master cylinder and if so what size did you use?

Hi Russ,

Standard master cylinder. You need conversion brackets to fit the callipers and also bigger discs with 15” wheels as well as different flexi pipes. They all come in the XR2 kit From Hispec .
