Westfield SE - Conversion from rear brake hub to Disk brake
Discussion
I've done this conversion on a previous car.
I used VW Polo Ali rear calipers, Sierra disc handbrake cable, Sierra rear discs.
Half shafts were then stripped down and the stud face machined flat, so that the disc will mount onto it true.
The axle has to come out and I used a rally parts specialist to make up the caliper mounts and weld to the axle, with the caliper mount offset measured using the disc centre and half shaft offset.
The whole thing was then re-assembled and some thin shims made up for the disc mounting and caliper mounts to ensure that the disc runs central to the caliper.
Finally the handbrake cable was modified to suit the VW caliper.

Burton power do conversion kits on page 123 of their catalogue. http://downloads.burtonpower.com/ecat2011/ecat.htm...
Not cheap though £500ish plus extra bits. Is it worth it? 80% braking is on the front so disks on rear shouldn't make that much difference I would have thought.

Drums are more than you will ever need for a Westfield. I believe the reason why they changed them to discs was just because of availability of bits and utilising sierra donor parts. My sierra calipers and discs just never bedded in on mine and that was with standard pads.
As said Rally design do kits, but £500 will get a pair of 4 pot alloy calipers fitted , which will do far more to braking that swopping out the drums. Remember you will have to reconfigure the handbrake cables and possibly the handbrake as well, as early SE had the escort handbrake and the sierra was on the late cars.
