Has anyone put in a tandem brake system for a 140?
Yes I used a XJ master cylinder bolted on a Triumph brake booster.
But I have a automatic XK140 and no clutch pedal in the way.
Also I converted the front brakes to Disks.
There is also a conversion kit for this on the marked, that has a clutch pedal.
Nick Green makes a bolt-on kit specifically for XKs here in the UK:
According to the advert, the kit’s designed for 140 in most variants and 120 RHD OTS, giving dual circuit, optional servo and a proportioning valve. If anyone would like Nick’s email address let me know.
THAT is a nicely done bit of kit!
I would like his email address. Tried to reach you off line but messed up
Unfortunately, due to liability issues Nick Green does not sell his dual system on the US
