To do the disc brake conversion you will need the following parts:
1x Left brake caliper complete.
1x Right brake caliper complete.
1x Brake pad kit.
2x Brake disc. For the 1.4 and 1.6 Duratec you will need 260 mm discs.
2x Brake caliper bracket.
2x Brake lines (hoses) for disc brakes.
1x Parking brake cable kit.
2x Guiding pin kit. This kits contains guiding pins and rubbers.
2x protection plate.
1 Liter of braking fluid.
In some countries like the Netherlands, Belgium and the UK the 1.4 and 1.6 Hatchback versions of the Focus MK2/MK2.5 are equipped with rear drum brakes. In other countries like Germany all Focus MK2/MK2.5 versions are equipped with rear disc brakes as standard. This means the conversion can be done easily using Original parts.
The braking system of the Focus MK2/MK2.5 is developed and produced by ATE (a company owned by Continental). Most of the needed parts are available from ATE as aftermarket replacement parts. These parts are identical to the OEM Ford parts and much less expensive.
Most of the parts I used where brand new. I only used new Original (ATE) parts and Brembo Brake discs and pads. Because new rear brake calipers and brackets were very expensive I decided to buy 2 rear brake calipers including the brake caliper brackets from a German scrapyard. After I sandblasted and rebuilded the brake calipers completely they where as good as new for a fraction of the price. The complete conversion costed me approximately €300,-. It took me about 3/4 of a day to do the conversion.
I wrote an English guide about converting the rear drum brakes to disc brakes. My guide can be downloaded from the following link:
