Here are the components required to convert your rear drums to discs.

If you have ABS, the sensors are identical & can be reused.

1142082 Spindle RH
1138520 Spindle LH
1138512 Hub assy x 2
1069295 Ring - ABS sensing
1060129 Shield LH
1060130 Shield RH
1075553 Caliper assy RH, not including pads
1075554 Caliper assy LH, not including pads
1323621 Rear disc - USE ONLY IN PAIRS
1009262 4 off splash shield rivets @ 9p each (not really needed)
1148270 brake hose 440mm x 2
1107698 brake pads
1253159 handbrake cable

If you use new parts from Ford, that list will come to over £800.

Most people buy second hand from a dismantler and/or use 'pattern' parts from a factors.



You can get a copy of the Ford general instructions on this conversion from here:
TSB 102/2003 - General Instructions for Converting Vehicles with Drum Rear Brakes to Disc Rear Brakes

Couple of points I can remember.

1) You don't really need to rivet the splash shields on. Just convenient instead of holding them as you bolt on the hub.

2) The hose support bracket can be difficult as (especialy on 'older' vehicles) the arm bolts are corroded into the bushes. Cable ties instead? but check every 3 months as they do age and break...
