Having fitted 265/75/16 tires to my Disco 1, I found that braking was not quite as good as I wanted and in particular I found that brake fade would set in much too quickly for my liking when pushing along mountain passes.
I knew that someone had fitted Defender ventilated discs and calipers to his car and decided to do likewise.
The calipers and discs bolt on without any mods needed.
All that is needed is a new hydraulic pipe from the flexible hose termination to the caliper.
No pics - it would look much the same as a Defender axle not so?
